2 WIN-WIN STRATEGY 1. Most shoreline development projects are actually zero-sum projects. Some get a luxurious mansion or a seashore dock for their yacht, while others lose a “wild beach” they used for many years to sunbathe, fish, or swim. Sounds like a clear example of social inequality and flashy consumerism. 2. Even projects aimed to create embankments or widen beaches are not liked by locals either, since the entire seashore will have to be crammed with cafés, rental shops, hotels, and sales points in order to cover the cost of such projects. What was once a tranquil and romantic beach now turns into a busy burger-selling, beer-pouring, money-making machine. 3. Civil discontent, eco-activists, protests - all that is common occurrence during any seashore construction. But is there a reasonable alternative? Or is the better option just to leave it all “as is”? 3.1 Most annoying factors for locals: * Restricted or paid access to the shoreline. * Impossibility to get into water in any place (like on a wild beach) because of support walls, tetrapods, embankments, balusters, and other obstructions. * No sand - the shore is paved or asphalted over. * Nowhere to swim (it’s too deep straightaway or there is a quay for small boats). * Dirty or stale water. * Noise, trash, and too many people. 3.2 Most desirable factors for investors: * A view of the sea * Extremely easy access to water [One Jump To Paradise]. * Possibility for comfortable seasonal living and/or seasonal berthing of small boats, water scooters and kayaks, or sailboats. * Availability of private zones. * Relative tranquility. * A promenade or a promenade area.

3 4. The best compromise that will satisfy everyone as much as possible is the concept of a Sea Village. It is a high-tech, contemporary interpretation of a “sea nomad village” - a settlement fully built above water 20-50 meter away from the shore and connected to it only via a long pier acting as an “umbilical” for public utilities. 4.1 This preserves the “wild beach” in its pristine form and ensures free access to it. 4.2 Cooperative construction makes it possible to considerably reduce the price for one square meter of palafitte and “parking space” for a boat. Such villages also allow to create developed public spaces and offer great recreational opportunities to the locals without taking anything from them in return. 4.3 A low cost of the water area and of the construction itself makes it possible to do away without any commercial space at all. In turn, this helps preserve privacy and tranquility. 4.4 What is more, building on bluff shores [without normal pedestrian access] or shallow banks allows for creation of an additional isolated artificial terraced beach. 4.5 The use of wet garages, groins, and fenced pools will help protect the village territory from sea waves without the need to create large water areas. 4.6 Widespread use of dry parking spaces (such as ramps or boat lifts) for water scooters, kayaks, and small boats will create a unique atmosphere of a marina but without any moles, and therefore without any damage to hydrobionts.

4 TYPES OF HYDRANTULA FITTINGS 1. Monofitting - a universal fitting that will be enough to assemble an entire structure (Y4, Y2, V3, K2, S3, S4, C7). 2. Bifittings - a set of 2 fittings sufficient to assemble an entire structure (B61+B62; L2+L1; R3 +R1; U45+M13). (!) There is often no clear distinction between bifittings and monofittings. For example, a full structure can be made not only from a combination of L2+L1, but also from L2 (without L1) or L1 (without L2) fittings only. The same is true with R3 (without R1) fittings and vice versa. Or B61 (without B62) or B62 (without B61). 3. Service fittings are fittings that ensure easy attachment of structures with concrete pumps - D2, J5 and D3. Generally, a fitting can be attached to a concrete pump with a standard concrete line (a flat ready-made cast-iron line or a hose). However, when building concrete structures far away from the shore, flushing and emptying the concrete line will be difficult. But using a disposable (sacrificial) concrete line from an HDPE pipe is a cheap and simple alternative. D1, D2 and D3 fittings make it possible to make a quick and inexpensive concrete line from a standard ∅125mm or ∅110mm HDPE pipe. 4. Functional fittings are fittings that perform the same function in different series of fittings. a) DS6 - alternating tread stairs for getting out of water; DS1 - a tread b) N2 - a hammock or decking bracket N7 - a hammock bracket N5 - a sun lounger c) M11, J11 - pipe manifolds d) X32 - frame top for a “pipe wall” e) D5 - a cantilever cap with attachments for mooring. 5. Standard structural shapes. In many cases, it makes more sense to use structural HDPE fittings (pipe bends, T-joints, adapter couplings) to assemble structures.

5 Terraced beach/ Seawall There are 4 different methods of coastal protection: * Seawall * Terraced beach * Groin * Gabions In the case with the Seawall, the goal is to find the most compact and inexpensive solution for preventing shore and seabed erosion by waves and create a smooth but sharp [> 45°] transition between “a flat high coast” and “a flat seabed”. Moreover, the protected bluff can be backfilled with fine rock fraction instead of select rubble. An easy access to the water may be ensured via a built-in staircase or not provided at all. A seawall is more preferable for marinas, moorage, breakwaters or when setting up wet garages, ramps, boat lifts or quays, i.e. anywhere where the pedestrian area is not intended for recreational use and where boats must be able to get as close to the shore as possible. The optimal solution for such tasks is to use seawalls based on U45/ Х32/M13 fittings. In cases when beaches are in use, easy access to water and aesthetics should be prioritized, which means it is more important to create pretty patterns from shorter steps [sand terraces] with creative shapes [zigzags, waves, or scales]. Hydrantula offers a tried-and-true solution based on Х31/X32/M13 fittings. Groins are constructed using Х11/Х32/M13 fittings. Gabions are constructed using the M5 fitting. Wet garage / Berth. A wet boat garage outside a marina (G1) is a seawall that goes down to the “seabed” and protects the “garage”

6 from three sides from waves and forms a base for a concrete wall frame. With proper gate orientation it will be possible to prevent accumulation of various deposits on the garage floor or waves hitting the boat shell. G1 structures are also suitable for cooperative storage of floating craft. Boatlift B61/B62 is a box-shaped construction form for assembling a boat lift with a canopy. A boat that’s lifted above water is safe from growth or corrosion and is unaffected by moderate sea. The box-shaped form can be covered with water-resistant materials. This shape also makes it possible to add a storage or a lounge room to the structure. It is also suitable for cooperative storage of floating craft. The V3 structure allows to winch a motorboat or a yacht on a metal skid or platform with rollers and supports on 4 or 6 angled rails. The V3 is multipurpose and can fit any contour. Boat ramp S3 / R3 - A lateral trolley ramp [S3] or a rail-gang with rollers [R3] make it possible to lift a boat [including a catamaran] out of water with a winch. A ramp attached to a moorage wall will allow to move the boat into a garage on the shore.

Wet Keelblock. There is a term called “navigation season”, which is applicable to almost all temperate and subpolar water areas. It may be defined by passage of commercial fish, seasonal storms, rainy seasons, or low water temperatures, when there is no practical reason to go out into the sea. During such periods, boats are often brought onto shores for repair or storage on skids. Hydrantula’s concrete skids allow to store floating craft on unequipped shores and even in shallow water, cutting costs and saving up marina space. Manifold. Unlike their plumbing analogues, Hydrantula’s manifolds are designed to allow for pipe passthrough through their housings; we also offer corner manifolds and even T-junction manifolds. Manifolds make it possible to construct large seamless “timbered” seawalls that can effectively dissipate wave energy. Auxiliary Fittings. Hydrantula also offers additional fittings for assembling cantilevers or concrete lines; attaching pontoons, setting up ladders into water, mooring PWC, etc. 7 PLUNGE POOL AND WAVE ENERGY. Most inexperienced builders of private embankments and quays think all a good structure needs is just a thick enough monolithic concrete wall - say, a meter thick. Just pour it in and your quay’s done! However, although such structure would be strong enough to withstand wave impacts, it does not guarantee long-term stability. Fast-forward to a couple years later, and our builders suddenly discover that their quay has eroded from below and is now either falling into the sea or “hangs from stilts”. Meanwhile, the shore behind the seawall is actively eroding and falling apart. Not only sandy or loamy soil can erode away, but even pebbles with the size of a fist. When sea waves monotonously hit the quay wall 24/7 all year round, all that energy has to go somewhere. Some of the energy (50%) turns into splashes and vertical spouts of water, some goes into abrasive wearing of the concrete. The other half, however, hits the seabed under the quay and erodes the soil

8 under the foundation. The effect remains strong until a depth of about 4 meters. Only quay walls that are at least 5 meters deep or more are generally not prone to plunge pool erosion. To slow down seabed erosion, it is important to either build a wide horizontal “seabed” shelf from a strong enough material (concrete, steel), or angle the quay wall “away from the sea” by about 30°-45° to help divert most of the wave energy away from the seabed and towards the top of the structure. Alternatively, it is also possible to replace the smooth wall with a more complex shape that will effectively dissipate wave energy. But the best approach is to use all three methods together. Or build the structure in such a way so that the plunge pool would naturally fill up with pebbles (boulders) from the gabion without a seabed or backfill of soil behind the wall. Hydrantula systems based on the U60 Jetty fitting have a timber-like wall with a 30° incline, which helps reduce the load on the seabed by about a half thanks to dissipation and diversion of wave energy upwards. Such wall can naturally fill up the plunge pool with backfilled pebbles and has a seabed shelf. Additionally, U60 structures have long back outriggers and a front shelf that act as skirts preventing the structure from toppling over into the sea with minimal backfill maintenance required. U60 systems also support attachment of berthing “tackles” for fixing small boats at a distance of up to 2 meters from the quay wall, outside the vertical stationary wave zone. X6 (Cribbs) and G4 (Sea Gabbio) fittings are modern versions of these structures that ensure stability thanks to effective wave energy dissipation “on the rocks” and automatically fill up the plunge pool with boulders comprising their own internal filling. Such systems can withstand breaking waves several times longer than standard quay walls in shallow waters. And thanks to their large mass, they are barely susceptible to freezing and ice drifts. These systems can also be used as breakwaters and underwater elements of walls for wet boat garages.

9 W2 concrete stationary skids by Hydrantula are perfect for storing floating craft above water when thereъs not much available dry space in the marina. Can also be used for Шpermanent mooringЧ of old yachts, motorboats and catamarans used as stationary houseboats. When combined with X6 or G4, they can be used to create whole communities in picturesque bays.

10 G4 gabions can be used as groins, breakwaters, coast- protecting structures or small moles. Lightweight when empty and tremendously heavy when filled with rock, the gabion is perfect for marine construction in remote bays.

13 The most expensive and the most useless port of a marina is the mole. Hydrantula technology can turn the mole into a marinaъs recreation center, its promenade through the breaking waves. U45 - A system of terraced support walls used to protect the mole at a depth of up to 12 meters, while also ensuring easy access to water and allowing to moor small boats. X11 - A groin system that allows to restore and maintain sandy beaches quickly and Шfor freeЧ or create artificial beaches at a depth of up to 3 meters.

14 System A is the foundation of life above water. It is designed for depths up to 5 m and can be used in tidal zones and areas prone to flooding. Reliable and frost-resistant, it is designed to last decades.

Y2 - a coastal structure for launching water scooters via rollers. Y4 - A deep-water structure with a longitudinal cradle for launching small sailboats and water scooters. Installation depth up to 3 meters. R3 - a structure for catamarans and centerboard-equipped boats. 15

An ideal sea cruise often doesnъt need any gasoline. Some marbled meat, a bottle of cognac, and the boys is more than enough. What youъll definitely need, though, is an unsinkable yacht with couches and a fire-pit. G1 - a system for 1-2 wet garages that in good hands can be seamlessly expanded with mess-rooms, bunks, and galleys. V3 - a system for 1-2 heavy berthing lifts, which can sometimes be turned into an entire floating villa. 16

Global warming and sea level rise [SLR] put up to 25% of coasts in the US and Japan at risk of erosion. Current coast protection methods are generally prohibitively expensive and fully strip coasts of any recreational potential. U45 - A system of terraced support walls used at a depth of up to 12 meter. Ensures easy access to water and allows to moor small boats. X11 - A groin system that allows to restore and maintain sandy beaches quickly and “for free” or create artificial beaches [up to 3 meters]. 17

Most clients start their journey in marine construction with the pier. The L1/L2 and C7 light pier systems are simple and reliable solutions for your first marine project. 18

A terraced beach is the easiest way to bring white sands where they have never been before. X32, X31 - a unique beach in the “fish scale” or “rhombus” style. 19

What can be better than stretching in a hammock on the beach? A big hammock above the waves! P41/ P42/P43 Series - hammocks right above breaking waves! 20

B61/B62 - a series of deep- water fittings suitable for building marine foundations for palafittes and boat lifts. May also be used on plots of land with regular floods. A boat lift is the best way to protect your boat from growth, osmosis, damage, and corrosion. 21

A marina at home with maximum comfort. If you live near water and have a shingle beach, the G1+M13 system will be perfect for a Шwet boat garageЧ: 24/7 access, wave protection, a dedicated space for storage and recreation. No more riding to the port - the sea is right here. 22

S3 and S4 are lateral cradle ramps for launching large motorboats and yachts. Can be installed as a duplex or triplex, including away from the shore. Maximum depth - 5 meters. Ice-resistant. Can be equipped with service rooms, sea ladders, and hammocks. 23

Combine separate marine construction structures into whole sea villages with our marine terraces and footways. L1/L2 - a light marine terrace system with built-in hammocks (for depths up to 2.5 m). C7 - marine footway system. K2 - shallow water footways (for depths up to 1 m). 24

Global warming and sea level rise [SLR] put up to 25% of coasts in the US and Japan at risk of erosion. Current coast protection methods are prohibitively expensive for private clients and rarely last long. U45 - A system of terraced support walls. M6 - A system of gabions. 25

27 Optimal and allowable SDR

28 LIGHTWEIGHT / 3D STIFFNESS. Hydrantula’s key advantage is that our ready- made structures have extremely low density - about 30 kg/m3, - while retaining great elasticity of the construction material and high volumetric stiffness of the welded plastic 3D form. This makes it possible to assemble on land, lift up with cranes, and install into water large monolithic structures, whose weight will then increase by 8-10 times after pouring in concrete. No other competing technology (except for Cribbs and Sheetpile backfill) show such a drastic weight difference. Their installation requires very heavy construction equipment and good access to the shore. SEAMLESS TECHNOLOGY. Even before Hydrantula, there were as many types of marine structures as there were “unique” methods of building them. Just like Hydrantula, each of these methods compete for attention from construction teams or larger contractors (B2B). However, few builders employ the entire specter of solutions available to them. As a result, a basically unified market of private marine construction has ended up divided into multiple artificial segments: * A market of sheet pilers and stilt drivers * A market of aluminum prefab assemblers (piers, boat lifts, ramps, rail gangs). * A market for wooden marine construction (piers, pontoons, terraces, boathouses). * A market for gravity support walls and Rip Rap. * A market for marina construction, concrete pontoons, and mole banking. * A market for coastal protection and preservation (tetrapods, groins). From the consumer’s perspective, this means contacting several contractors (and deal with various conflicts, such as “who should’ve done this” or “who should be responsible for that”) in order to fulfil a complex marine construction projects, or hire a general contractor and pay for its services.

29 Meanwhile, any so-called “optimizations” from various technological solutions are cancelled out by high capital intensity of such businesses, high costs of logistics, and high rates of various niche specialists who operate in dangerous conditions and in bad weather. From the builders’ perspective, instead of a big and “juicy” unified market, they are part of only one of its smaller segments. Covering the entire market as a whole is impossible either due to high capital costs of construction machinery and equipment or due to lack of workers with proper qualifications. Hydrantula is the only technology that can “fill” all segments of the private marine construction market based on unified technological solutions, one material supplier and one contractor. Besides, the contractor will only require one set of inexpensive tools and one team of all-rounders. 1. Competing technologies: 1.1 Floating concrete pontoons 1.2 Pile fields (steel, concrete, bored, wooden) 1.3. SheetPile Larssen (Larssen sheet piling) WHY HYDRANTULA IS A DISRUPTIVE INNOVATION ? 4.1 The private marine construction market is still dominated by technologies used in Ancient Greece and Medieval Venice: stilts hammered [vibropiled] into soft sea ground and embankments, and foundations from large log crates filled with big rocks (essentially gabions). Obviously, it is impossible to create a stylish brand around hammering wooden or steel stilts. Besides, neither the raw materials (logs), nor the technology employed for this leave any space for patents, know-hows, or price edge. 4.2 One of the more recent technologies of note is steel or PVC Larssen sheet piling. However, even Larssen sheet piling was invented in 1906. Technically, it is just sheets with indentations and locks that can be put together into a seawall. In many cases, it is still cheaper to simply hammer in (or wash) a row of wooden stilts put close together.

30 4.3 The main characteristics of modern private marine construction are: * Primitive materials (logs or steel pipes). * Structure costs very commonly including machine hours of heavy machinery (that must work continuously for weeks) and qualified labor of excavator operators, crane operators, flatbed drivers, or barge captains. * Large business entry investments (up to $200,000 per team.) * Duration of work being highly dependent on the weather. 95% of all “wet” work is done on-site and above water only. * A lot of raw-material waste due to bottom geology and the impossibility to cut the material perfectly * 50% of water areas having prominent seasonality, rendering winter work impossible. * Construction teams being able to work only within 100-150 km radius from their base. As a result, neighbors will be suffering through unbearable noise and diesel fumes, and the structure will have a short service life and will soon require repairs. 4.4 All these factors make business scaling ineffective, as there is practically no opportunity to save on the size and nothing for the extra workers to do in winter. 4.5 This is how Hydrantula’s technology revolutionizes the workflow for private marine construction: * At least 50% of all operations (and sometimes even up to 90%) are done in a shop. Shops also make it possible to produce semi- manufactured products during winter for storage. * Semi-manufactured and ready-made products can be transported on lowbed trucks across thousands of kilometers. * Most workers can be trained from scratch within a week. They will not need prior heavy machinery certification. * Involvement of heavy machinery is reduced to 1-2 days (or by 5-7 times). * Initial tool investments can be brought down to $5,000 for the team (dealer). * Work at the installation site generate practically no noise. * Service life of Hydrantula structures is up to 60 years. * Wasted material is no more than 10%.

32 3 LAYER OF INNOVATION 1. Hydrantula is a leader in the underwater concrete and private marine construction market and the maker of a series of innovative products and groundbreaking ways of their use. Hydrantula’s innovations can be divided as follows: 1.1 Unprecedently wide range of products, including products that are not offered anywhere else in the market. 1.2 Innovations at individual product level, designed to ensure high stiffness and low weight of the structure at a low price. Simple logistics of components. Compatibility with standard pipes and valves, as well as with concrete pumps. 1.3 Innovations at structure level designed with scalability, versatility, easy and fast assembly, easy installation, and minimal construction equipment and barge rentals in mind. Dry work (mostly in shops) regardless of weather conditions. Possibility to install Hydrantula structures in “wild” conditions in the field. 1.4 Innovations at water village or boat cooperative level. 2. Innovations in fittings: 2.1 Camlock / Groove Lock - semi-sealed connector on Hydrantula fittings for pumping in concrete under pressure into Hydrantula structures down from the 2.2 Anti-Bell - a collar shape on a fitting with a characteristic narrow lip at the end. Allows to edge weld (to the narrow end of the collar) a pipe top that is mechanically compatible with GrooveLock and Camlock standards.

33 with the same exact diameter or fix it in a much wider flaring by welding the seam with a hand extruder. The flaring is then drilled out with a drill bit for easier removal of the collar end. This product ensures the most reliable installation of a pipe beam between to anti-bell-type collars. 2.3 Binary socket is a patented design for attaching pipes to Hydrantula fittings characterized by arbitrary elevation and bearing angles relative to the fitting’s equator plane (during plastic molding) with a possibility to “include” a pipeline at the installation site by drilling it out with a drilling bit. 2.4 Side Offset applies to offsetting sideways the axes of aligned collars or binary sockets relative to the geometric center of the 3D form’s lattice point in order to ensure straight-through joining of the whole pipe beam and making the fitting more compact. 2.5 Welded joints - the use of standard methods for installing HDPE plumbing pipes for welding, which doesn’t require developing special tools or teaching workers specific skills. Standard equipment ensures great durability and appearance of the seam at minimum cost and with minimum time. 2.6 Composite/Cable pull-up - pipelines for installing rods from “raw” composite 16-40mm rebar rebar (not in concrete) that act only for stretching (as anchor lines). Structurally, they are similar to binary sockets for pipes.They ensure high volume stiffness of the structure with minimum added weight and cost. Cable pull-ups are innovative nodes for attaching anchor lines made of 3-5mm stainless steel cable to ensure required stiffness of the empty formwork during its transportation and installation at the given site in the water area.

34 3. Structure innovation: 3.1 Node-Beam 3D frame is a method for creating formwork for concrete 3D farms using standard plumbing pipes as beams and fittings with 5-16 sockets and patented design as the forms node elements. 3.2 Skewer-tube / Co-axial socket 3.3 Buildability - The design of Hydrantula structures prioritizes easy installation of the 3D form made of fittings with over 5 non-axial sockets (and sometimes up to 16 sockets). This is definitely unachievable with just traditional methods of installing PE-based or plumbing systems. 3.4 Wet casting - a method for casting concrete into the submerged framework by pushing water from the bottom upwards. 3.5 Built-in pontoon - a method for delivering and/or installing Hydrantula structures on-site on account of the 3D forms guaranteed buoyancy achieved through blue 217L barrels attached to it with special F200 holders. 3.6 Hose concrete conductor - the use of high-pressure hoses (up to 18 bar) 150mm in diameter and up to 40 meters in length as disposable underwater concrete lines. 3.7 Pressurized sewage/DC power/Potable water supply 3.8 Framed stacked wall - a method for constructing an underwater wall from a bunch of horizontal HDPE pipes (= hoses) tightly fixed in several frames of the 3D structure. This makes it possible to use pipes in long stock lengths even for relatively short marine terraces. 3.9 Manifold - fittings for “centralized” concrete casting of several horizontal pipes in a bunch (in a seawall). Also ensure sealing of pipe ends and are used to create

35 right angles in walls. 3.10 FitFitting System - an innovative method for creating 3D forms from pipes with circular sections and diameters over 5”. Replacing “pipe-pipe” connections to “pipe- fitting” connections in a structure fully eliminates the need for labor-intensive forming of pipe edges and significantly reduces the accuracy required for cutting them lengthwise. 4. Innovative formats: 4.1 DUNE - a method of coastal protection and restoration of sandy beaches using terraced seawalls. 4.2 Zero Line - a method for setting up mooring spaces for small boats and resort communities in shallow waters without any moles, which helps retain free access to the coastline and normal water circulation in the bay. 4.3 SeaVillage - a compact settlement designed for recreational and athletic purposes at the zero line and combined with camping and collective parking space for small bots [a mix of dry and wet berths]. 4.4 BoatCondo - structures designed for dry storage of two and more boats above water. This collective storage helps save up on up to 30-50% of the fittings and pipes (common wall effect) and at the same reduce the occupied water area. 5. In addition to other traditional products for the sector, our product line also includes: 5.1 Terraced support walls. 5.2 Terraced beaches 5.3 Gabions 5.4 Sea causeways 5.5 Boat condos 5.6 Wet garages 5.7 Deep-water boat ramps 5.8 Sea camping 5.9 Wheeled lifts

36 VALUE OF HYDRANTULAS TECHNOLOGY FOR CONSUMERS AND SOCIETY 7.1 In most countries (except for Finland, the East Coast of the US, and some Persian Gulf countries and insular nations in Oceania),the shoreline and the seashore are considered a scarce resource that must be developed only in the interest of society and for some common good rather than in pursuit of solely private interest. Having enough money does not mean being able to develop the shoreline however you wish. And most historically developed coves and marinas regularly become targets of criticism and revisionism from political and environmental activists. 7.2 The value of Hydrantula’s technology is in its ability to double the recreational potential of water areas by preserving the coast in its pristine condition and moving marine structures 25-70 meters further into the sea, including into areas too deep to be suitable for swimming. At the same time, our structures do not hinder normal water circulation and do not cause waterlogging. 7.3 They also make it possible to terraform coves without wide natural sand beaches into terraced beaches and seafronts. 7.4 Hydrantula allows to create marina moles that are perfect for recreation and retail and aren’t just obstacle courses from tetrapods. They are also ideal for collective (cooperative) secure quays for small boats that do not require a special mole (with ramps and ship lifts). 7.5 Additionally, Hydrantula marine structures are easy to dismantle and can be constructed without generating any noise.

37 7.6 One of the main challenges of shallow water construction is preserving the balance of bottom deposits. Construction of pretty much any continuous structure leads either to the formation (or wash-over) of sand or pebble dunes, or to bottom erosion, which is the exact opposite (and often to both at the same time). As a result, the structure will slowly sink into bottom deposits or its foundation will be exposed and suspended without touching any solid ground. But we managed to find a perfect balance. All this makes Hydrantula a very attractive and socially and environmentally responsible technology for marine construction. VALUE FOR DEALERS, CONTRACTORS, DISTRIBUTORS, ARCHITECTS, AND STORE CHAINS: 8.1 Unlike most alternatives, our products have a bright and memorable design that is one-of-a-kind. A colorful palette reminiscent of M&Ms or LEGO sets us apart from the mass of monochrome (black or white) construction materials, giving us an advantage. 8.2 Unlike the alternatives, most of which were developed in the early to mid-20th century, our technology is brand new and is protected with international patents. 8.3 Unlike most other known methods of marine construction, our structures can be assembled or semi- manufactured up to 60-70% readiness in a shop environment

38 all year round and transported over long distances. Better yet, weather conditions or availability of amenities at the installation site is almost never a problem for us. 8.4 Our formwork has multiple competitive advantages compared to traditional technologies and expands the realms of possibility for private marine construction on a budget. 8.5 A whole range of products in H2, H5, and H6 series simply cannot be implemented with currently existing technologies. 8.6 Our technology does not pollute water with zinc or heavy metal ions, toxic treatment agents, or carcinogenic antifouling solutions. UNEVEN SEABED. HYDRANTULA systems are truly very simple to assemble. The hardest part is actually finding or making a flat enough seabed to install them. Since all Hydrantula systems are 3D forms with regular shapes, they need a flat seabed to be level. 1. If you own a quite large water area, we recommend finding a relatively flat spot which can be perfected with a water cannon. Sometimes all that is needed is to inspect a part of the water area that is 3-5 meters farther from the shore line, where the seabed is generally much flatter 2. If the entire water area sits on a noticeable uniform slope, this can be balanced out by installing vertical columns directly below the deck or at the very bottom (below the form’s lowest section). 3. If you have the ability to rent a barge with seabed clamps or an excavator with a long arm, you can simply dig out a perfectly flat area right before installing the structure. The area will inevitably be covered over by storms, but the structure will remain flat. 4. Sometimes, one or two large boulders on the seabed can worsen the situation. These can be “fished out” with a crane or a bulldozer with a stainless- steel cable seine net and removed beyond the construction site boundaries or even drag onto the shore. 5. Columns that are suspended in air (sags) can be fixed using screw piles screwed inside Hydrantula structural columns. 6. Small sags can be fixed by putting stone pavement slabs under the structural columns. 7. To sum up: in most cases, seabed defects can be fixed,

39 or you can use an initially good part of the seabed. However, there are seabed areas that are clearly not the best for installing Hydrantula structures, and in this case it is better to consider other options. That’s why we recommend forming at least a very rough understanding of how your seabed looks before purchasing a Hydrantula structure. APPLICABILITY. In Hydrantula brochures, various fittings have predetermined “functions” for piers, terraced embankments, or boat lifts. However, with enough ingenuity, they can undoubtedly be used for any other purpose, such as for agricultural structures, footbridges, swings, or smaller architectural objects. Note: Hydrantula does not offer any advice or give any guarantees regarding any possibility of alternative use. We absolutely cannot guarantee the safety and rationality of such experiments or the possible consequences for the property, health and wellbeing of their builders or users. Perhaps if you have an engineering degree and enough experience in building with cast concrete, then you might (and even that is not a given!) correctly foresee all the possible consequences of your actions, but in any other case it’s better not to take any risks. We designed our products based on temperate water areas, such as ice-free saltwater bays or a freezing lake. Our structures were not tested or designed for use in the Arctic or in areas with frequent icebergs, storms, tsunamis, or tornadoes. They are also not intended for use in water areas with very high waves, strong currents, or the abundance of large floating debris. While reinforced marine concrete is a durable and long-lasting material when cast properly, it is still possible that our structures may be useless, insufficiently durable, or even dangerous to use in water areas with extreme water or ice conditions. When considering to purchase a Hydrantula structure, use your best judgement, the experience of your neighbors near your water area, sufficiently accurate engineering calculations, and recommendations from Hydrantula specialists.
