SERIAL ASSEMBLING & INSTALLING BASICS EN

HYDRANTULA BATCH ASSEMBLY: THE BASICS 1. LOCATION OF ASSEMBLY PLANT 1.1 When choosing a location for your assembly plant, prioritize locations near large bodies of water, or in close proximity to them if they allow for launching and transportation of oversized cargo up to the shore line. 1.2 If the assembly plant cannot be located near water, prioritize locations near multilane highways with easy access for large lowbed semi-trailers (up to 20 m). 1.3 Locations near HDPE pipe manufacturing facilities are also highly preferable. 1.4 The minimum temperature for polyethylene assembly is +10℃. Use a warm shop when operating in colder climates, or perform assembly seasonally. 2

2. ASSEMBLY SLAB (CANOPY). 2.1 Assembly should be done on a perfectly ﬂat, horizontal concrete slab (berth) with the following dimensions: * Slab width: 200-250% of the structure’s max. required width. * Slab length: may be less under 200% of the structure’s length (but no less than 150%) provided there is a sufﬁciently ﬂat area always available near the concrete slab that is approximately level with it and has at least 100% of the structure’s max. length (for installing long bars during assembly). When assembling in a cold climate, the length of the warm shop must be 220% of the structure’s maximum length. However, 50% of its area may have ceilings 3-4 m in height and without telpher coverage. 2.2 When assembling in a windy, rainy, or hot climate, assemble the structure under a canopy or in a cold shop rather than out in the open. Canopy height must be 250$ of the structure’s maximum width and height (depending on which is higher). The canopy must be equipped with an electric telpher on a ﬁxed rail at the center of the canopy. The telpher (hoist) must have a bearing load 180-230% of the structure’s max. weight. (Recommended bearing load: 8-10 t). It is also recommended to have a second hoist on a movable beam with a bearing load of 3-5 t. 2.3 Based on the above, the optimal canopy size for most applications is 24x12 m with a height of 10-12 m to the upper telpher level. When assembling in an open area, ensure regular access to a mobile crane or a crane truck. 2.4 The slab must have mounting rings with at least 4 t of bearing load and 180-250 cm orthogonal increment embedded ﬂush into it. These rings are used for mounting hoists and locking HYDRANTULA ﬁttings during assembly. The berth should have at least four 220V 20-25A double sockets and possibly three-pin sockets (if 380V tools are used). They should also be equipped with ﬂoodlights for 3

work during nighttime. 2.5 The site or the canopy must have structural concrete columns at least 80 cm high with several rings (at 20 cm increments) suitable for mounting hoists horizontally. All mounts must have a bearing load of at least 5-6 t. The columns must be installed at 2-3 m increments from one long and one short edge of the slab or canopy and must not obstruct access for lowbed semi-trailers and cranes or hinder transportation of the assembled structure. It is recommended to install supports on the outer side of the columns to organize storage of bars and pipes with long stock length. 2.6 The slab may be marked out in squares with 1 m increments for convenience’s sake. 3. GENERAL PROCESS STEPS: OFFICE: 3.1 Measure the bottom. 3.2 Design the individual structure as a 3D object in STEP or GLB format, or choose a standard structure from the catalog. 3.3 Prepare estimates (BIM), 3D mock-ups and color samples for the customer, purchasers, and shop personnel. 3.4 Draw up blueprints and measure out pipes and ﬁttings for shop personnel. Personnel: 1 person WAREHOUSE: 3.5 Provide the shop with pipes, rebar, and ﬁttings from contractors or from your own warehouse. 3.6 Label the ﬁttings and pipes with a white marker. Personnel: 1 person. SHOP: 3.7 Assemble reinforcement cages from rings and rebar. Personnel: 2 people. It is recommended to use composite or stainless-steel rebar cages tied with wire. For form pipes placed in freshwater above the waterline, (epoxied or galvanized) steel rebar may be used. Standard steel rebar or welded rebar stacks will shorten the structure’s 4

service life. 3.8 Prepare ﬁttings (drill pipelines) and weld the edges of structural columns. Also weld expendable concrete wire. Personnel: 2 people 3.9 Assemble the structure planes onto bars and weld the edges. Personnel: 2 people To be performed on the main or smaller berth. The smaller berth should be used if the main berth is under heavy load. The smaller berth must be 200% of the structure’s max width and 150% of the structure’s max height. Also ensure that the berth has a solid, clean and ﬂat surface area for “storing” the planes 3.10 Install the 3D structure onto the bars and butter them with an extruder. To be performed on the main berth. Personnel: 3 people. 3.11 Transport or tow the structure to the customer. Personnel: 1-2 people. 5

3.12 Shop capacity is approximately 1 structure per 3-4 days with fully paralleled production (personnel: 11-12 people) Production time of an individual structure is 9-12 days from delivery of all the materials to the shop and approval of the 3D mock-up. 3.13 With a minimum-sized team of 4 people, shop capacity is 1 structure per 20 days, production time is 20 days. 4. DELIVERY OPTIONS FROM HYDRANTULA: 4.1 HYDRANTULA offers delivery of ﬁttings, colored columns and colored cross bracings, as well as composite rings on demand (BIM) by shipping companies in returnable 90x90x160cm or 100x100x150cm big bags in quantities corresponding to the big bag’s volume. 4.2 L bars are shipped as oversized cargo (stock length). 4.3 We do not ship bars (or any pipes longer than 220cm) or composite rebar in stock length or in rolls. 6

1. TOOLS 1.1 For assembling HYDRANTULA structures, you will need a butt welding machine with a maximum working diameter for HDPE pipes of 280mm [250mm for H2] Exception: HYDRANTULA Series H3 and H6, which use pipes with a diameter of no more than 160mm. 1.2 In addition, you will need a drill and a set of hole saws [125; 140; 160; 205; 220; or 250mm] or spade bits [16; 24] For sockets and cuffs, as well as binary nozzles, you will need a hole saw with a diameter equal to the pipe’s outer diameter [OD]. For cuffs intended for butt welding, the hole saw diam- eter should be equal to or slightly smaller than the pipe’s inner diameter [ID]. As a rule, this is the nominal OD minus 16–25mm. A purely mechanical pipe-to-socket or pipe-to-cuff connec- tion can be replaced with socket/butt welding. In this case, the hole saw diameters are determined by the geometry of the welding machine’s heating element. For small-diameter holes [16, 24, 40mm], the hole saw can be replaced with a spade bit. 1.3 Temporary ﬁxing of pipes in cuffs, sockets, and binary nozzles can be done with rivets or self-tapping screws (if you are unsure about the correct positioning of the ﬁtting/pipe). Permanent ﬁxing is only done with a manual extruder! 1.4 For cutting pipes “to size,” you will need a miter saw or a large-diameter pipe cutter. Single cuts can be made with a reciprocating saw or an angle grinder. 1.5 For cutting windows in skewers (for monolithic concret- ing) – an electric jigsaw or reciprocating saw. 1.6 You will also need markers, tape measures, levels, step ladders, or scaffolding. 2. INSTALLATION OF BEAMS AND LOAD- 8

BEARING COLUMNS 2.1 As load-bearing columns in Hydrantula, HDPE pipes of the following diameters are used: 280mm (Axx, B61/B62, C7, S4, DS6), 250mm (S3, R3), 225mm (L2, L1, V3, K2), and 200mm (Y4). Installation of these load-bearing columns is carried out only by butt welding and cutting an opening in the end of the cuff with a hole saw. 2.2 In some ﬁttings (L2, V3, U45), sockets are used, which can be welded with a manual extruder. 2.3 Installation of beam pipes. HDPE pipes of 160mm (S3, S4, R3, Y4, Y2, C7, L2, U45, X31, X11, G1, X32, K2, V3) and 140mm (Axx, B6x, U45, P4x, P5, G1, S3, DS1) are used as beam pipes. Installation of beam pipes is carried out in various ways: butt welding, socket welding, and manual extruder welding. 2.4 Installation using electrofusion couplers is severely limited by the signiﬁcant tolerance in ﬁtting cuff diameters (up to 2–3mm) and the difference in melting temperatures between HDPE (pipe) and MDPE (ﬁtting). Mounting holes for butt or socket welding are cut out with a hole saw. 3. Installation of Wall Bundles HDPE pipes of 125mm (M13, M5, X31, U45, G1, X32, X11) and 110mm (X11) are used as pipes for wall bundles. The main installation method is manual extruder welding and, where possible, butt welding. 4. Installation of Special Concreting Fittings (D2, D3) This is carried out by butt welding. 5. Installation of Composite Tie Rods This is carried out with a manual extruder or using aluminum compression couplers. 9

6. FEATURES OF CUFF ASSEMBLY 6.1 Cuffs can be connected to pipes by socket welding or butt welding, or welded with a manual extruder. 6.2 A continuous (monolithic) pipe (with a window inside the ﬁtting) can also be connected to through (coaxial) cuffs [skew- ers]. 6.3 Similarly, the rebar package can be split (up to the ﬁtting) or continuous (through the entire skewer). 6.4 For successful socket welding, a hole is cut in the end of the cuff that is 5–6 mm smaller than the pipe’s outer diameter (and 2+ mm smaller than the welding “male” insert from the socket welding kit). This ensures contact melting of the ﬁtting material. 6.5 Preparation for welding: The pipe end and the hole in the ﬁtting cuff must be clean and dry. If necessary, the pipe end is machined to create a smooth edge. 6.6 The required insertion depth of the pipe into the cuff is measured and marked with a marker – approximately 10–12 mm is recommended. The pipe end and the hole are cleaned of the oxide layer im- mediately before welding, as it reduces joint quality. 6.7 A heating tool (soldering iron) is selected with a power rating corresponding to the pipe diameter and wall thickness. The hot “female” sleeve of the soldering iron is placed over the pipe end. The heated “male” insert is inserted into the hole in the ﬁtting and held for the time required to heat the PE to melting temperature. Heating time depends on the diameter and wall thickness of the pipe, as well as the material type. 10

6.8 Joining. The heated pipe end and the hole in the ﬁtting are quickly removed from the soldering iron attachments and forcefully inserted into each other until they stop. The parts must not be rotated relative to each other. 6.9 The joint cools naturally, without bending or movement. Cooling time also depends on the pipe diameter and thick- ness. 6.10 Quality control. After cooling, the weld is inspected for defects and misalign- ment. It is necessary to ensure that the joint is secure and leak-tight. Improper welding can lead to reduced joint strength. 6.11 The heating temperature must be appropriate for the pipe material (for example, for polyethylene – approximately 200–230°C). 6.12 Work with hot polyethylene parts should be carried out with gloves. 7. CANTILEVERS 7.1 Pipe-beam sections located beyond the outermost ﬁtting, outside the truss (cantilever), are the simplest way to increase the usable area of the structure. Fitting N2 can be used in- stead of a pipe. 7.2 Cantilevers must have seamless internal reinforcement with internal beam pipes. 7.3 The unsecured (free) end of the cantilever is closed off with a welded cap or a special D5 ﬁtting. 11

CONCRETE RECIPE FOR HYDRANTULA STRUCTURES The concrete recipe for Hydrantula structures depends on the type of water body (freshwater, marine); the climatic zone (freezing or non-freezing water body); and the rheo- logical requirements for the fresh concrete. It also depends on the availability of raw materials (pozzolans, alumina ce- ment). The most universal recipe: Cement content: from 450 to 600 kg/m³ Water-to-cement ratio: from 0.35 to 0.46 Sand-to-aggregate ratio: from 0.42 to 0.5 Fines content (sand+): from 360 to 500 kg/m³ Maximum nominal aggregate size: from 10 to 19 mm Silica fume: from 0 to 6% Limestone powder: from 0 to 20% of cement content Superplasticizer: 0.05... 2.65% Anti-washout admixtures: up to 0.26% • The content of cementitious materials in the range of 450 to 600 kg/m³ • Water-to-powder ratio from 0.35 to 0.46. • Sand-to-aggregate ratio between 0.42 to 0.5 • Fines content (360 to 500 kg/m³) • Water-to-ﬁnes ratio (0.85 to 1.0 by volume) • Nominal maximum size aggregates (10 to 19 mm) • Silica fume (0 to 6%) • Limestone powder (0 to 20% of cement content) • Superplasticizers are usually employed in the mixture with 12

a dosage of 0.05%–2.65% to increase ﬂuidity and allow for the reduction of the water-to-cement ratio and thus, higher strength. • There is a risk that concrete cast underwater may segre- gate and wash out. That is why a special type of admixture called “anti-washout admixture” is added to the mix to en- hance its yield value and viscosity, with a dosage between 0.005% and 0.265%. In terms of concrete properties, underwater concrete: • is highly ﬂowable concrete that can ﬂow and spread only under its own weight; • can achieve good compaction without the need for vibra- tion; • has high strength; • sets and hardens rapidly; • has a low tendency to segregation and bleeding; • maintains stability of its properties. This makes it perfect for special applications such as self-compacting concrete, underwater concrete, shotcrete, and cement grouts; • has better cohesion when placed underwater and thus less risk of washout or segregation by surrounding water. Increasing the dosage of anti-washout admixture decreases the dispersion rate of concrete, which is a beneﬁt for under- water concrete. Limitations of Using Anti-Washout Admixtures Some limitations exist for certain types of anti-washout ad- ditives, which are: • Lower strength and modulus of elasticity, which can reach only 80% of the values obtained for concrete without an- ti-washout admixtures. • The above point may lead to slightly higher amounts of steel reinforcement. 13

Flow-rate columns: ΔP = 1.5 bar = 150 000 Pa, L = 10 m. Pressure-drop columns: Q = 50 L/min = 8.333×10⁻⁴ m³/s, L = 10 m. B30 S5: μ = 50 Pa·s (high-slump, very pumpable). B30 S4: μ = 100 Pa·s (medium-high slump — ap- prox. double S5 viscosity; Q(S4) = Q(S5)/2 for equal ΔP). Re < 10 for all cases conﬁrming laminar regime. max = calculated ﬂow rate exceeds 300 L/min — pipe bore is oversized relative to typical pump output; pump capacity becomes the limiting factor. Practical note: at 1.5 bar, S4 mix reaches 300 L/min threshold one pipe size later than S5 (∅225 vs ∅180), re- ﬂecting its higher viscosity. For ∅90 mm the ΔP values at 50 L/min (5.8 bar for S5, 11.6 bar for S4) exceed typical small-pump ratings — this diameter is at or beyond its practical limit for pumpable concrete at that ﬂow rate. 14

1. WATER AREA SURVEY 1.1 First, it is necessary to survey the boundaries of the water area, in which marine construction is allowed. These boundaries are generally deﬁned by the boundaries of a seafront lot or in a waterbody lease agreement. 1.2 Then determine minimum distances from the water area’s boundaries for various types of hydrotechnical structures to establish a construction footprint. 1.3 Measure the depth and bottom slope within the selected part of the water area. 1.4 Also collect data on the bottom soil to ﬁnd its approximate bearing capacity and erodibility. Also determine the size of large “random” rocks that may hinder installation. 1.5 Study the possibility of ice drift in case the body of water freezes in winter.. 2. DETERMINE THE TYPE OF THE HYDROTECHNICAL STRUCTURE YOU WISH TO BUILD AND ITS ADDITIONAL FUNCTIONS AND RECREATIONAL CAPABILITIES. 2.1 Find a local contractor, handyman, or a construction team for DIY work. 2.2 Find a HYDRANTULA dealer. 2.3 Consult with the dealer and choose the ﬁtting models you wish to build. 3. ORDER THE MODELS FROM THE HYDRANTULA DEALER DIRECTLY OR VIA A CONTRACTOR AND DECIDE ON REBAR AND PLASTIC PIPE SHIPMENTS. 17

HYDRANTULA MATERIALS The non-removable HYDRANTULA formwork is made from HDPE and MDPE - two types of food grade polyethylene. Although plastic may not sound like a very green material at ﬁrst, in this case it is the safest and most environmentally friendly option. 1. Unlike wood, HYDRANTULA does not need toxic treatment for a longer service life in water. Untreated wood will rot away in freshwater in 10-15 years. And in seawater, it will be destroyed by shipworms in 5-8 years. Only rare and expensive types of tropical wood (teak, ipe) are relatively resistant. As a result, wood is increasingly treated with agents containing heavy metals, organic toxins or hazardous petroleum residues. 2. HYDRANTULA does not emit ions of heavy metals (Zn, Mn, Cu, Cr) into water, unlike galvanized steel or marine grade aluminum alloys. These ions make water undrinkable and reduce the biological productivity of many organisms. 3. HYDRANTULA structures are not a major source of microplastics. Over 88% of all microplastics in the ocean comes from plastic wraps and synthetic ﬁbers (propylene rope, discarded ﬁshing nets, synthetic fabrics and nonwoven materials, such as wet wipes). Another 10% comes from plastic bottles and disposable tableware. In general, about 99% of all microplastics in the ocean is generated by domestic waste, composite materials, and ﬁshing nets. Massive plastic structures degrade a hundred times slower and do not pollute water as much with microplastics. 18

X-DAY So, your structure is assembled and is near the installation site. It may stand on the beach or in water. If it has been transported on a lowbed truck or a ﬂatbed with a loader crane, or fully assembled on the beach, all you will need to do is submerge it into water: 1. Lower it into water with a crane right into its ﬁnal place. To do so, you will need a powerful crane with a long boom at the shore line (in other words, the crane must drive onto the beach or the embankment). This will require a prepared “last mile” of the rode. Alternatively, place the structure in water near the required installation site in such a way so that it ﬂoats and does not topple over. The structure’s total internal volume is generally 4-5 times larger than its weight, so it will barely submerge (less than 25% of it will be underwater) and will not be stable enough if it is fully sealed. Pouring concrete into a fully sealed and ﬂoating form will be very difﬁcult; the structure will very likely topple over. As such, forms are generally made with many holes so that they could better submerge. HYDRANTULA structures have near-zero buoyancy when ﬁlled (they are slightly lighter or slightly heavier than water). As a result, the natural immersion level of such structure is deﬁnitely higher than its design installation depth. Because of the higher immersion level, they will be impossible to tow to the installation site. Submerged structures require several pontoon to keep the immersion level moderate (knowingly less than their installation depth). 3. HYDRANTULA has a special F200 ﬁtting for precise mounting of blue plastic barrels with 217 L of volume to the structure’s beams as 19

removable pontoons. Several of such barrels placed properly at the required height will ensure sufﬁcient immersion and stability of the entire structure. 217L barrels have bung holes with special valves that allow to slowly “bleed” the air out of them and ensure gradual “immersion” of the structure to the bottom. Barrels without any air will have minimum buoyancy and can be easily removed from the F200 ﬁtting hoop and dragged onto the beach. 4. In calm water areas, the assembled form with 217L barrels installed above the structure’s midpoint (height wise) can be towed by a motorboat or a jet ski to a sufﬁcient distance, which helps avoid coordinating transportation of oversized cargo on public roads. 5. In case of installation on the sea, the structure can be transported on top of a barge (incl. with heavy construction equipment), or towed in semi-submerged state as described in above in item 4. 6. The structure can be unloaded from the barge with a built-in crane or an excavator with a sufﬁciently far bucket outreach. Alternatively, you can use a mo- bile crane on the shore or drop the structure by tying it to the shore and sending the barge astern. 7. Warning! Dropping the barge can be dangerous and may lead to the form toppling over or cause injury to the personnel involved in the operation. It is recommended to use trolley jacks or wheeled carts to make it easier to drag the structure overboard. Keep in mind that the jacks or carts may be damaged or lost (sunk) as a result of this. 20

8. For all installation methods except for precise installation into the site with a crane, it is recommended to weld the F200 ﬁtting to the structure beforehand so that it could be moved in case the ﬁrst attempt to install the structure is unsuccessful. 9. Once the structure is installed in its ﬁnal position, it is strongly recommended to have snorkel or scuba divers perform a total check of the structure for signs of any mechanical damage, deformation, bent pipes, large rocks hitting the structure’s horizontal beams or struts, or the structure’s spans being suspended without touching the bottom. Make sure there is no excessive tilting or buckling of any of the form’s elements. Also pay attention to any loose parts, ruptured weld seams, fallen out composite rods or unlocked concrete wire clamps. 10. Proceed to pouring in concrete only once you are absolutely sure the formwork is technically sealed (has acceptable expected volume of fresh concrete leakage) and can withstand the weight of fresh concrete without destruction, toppling over, or excessive deformation. 11. For systems with height adjustable struts, adjust them to the bottom features. 12. If concrete cannot be poured in immediately, it is recommended to add ballast to the structure (with a total weight of 200-300% of the structure’s own weight in air) to avoid it being dragged across the bottom, toppled over, or caried away by a wave into open sea during a storm. 21

13. The part of the concrete line to be submerged when pouring concrete must be mounted on the shore in advance. 14. HYDRANTULA structures are compatible with standard cast-iron concrete lines, high- durability rubber hoses, and single-use concrete lines with special HYDRANTULA D2, D3 ﬁttings and a plastic HDPE pipe or ∅150 ﬁre hoses and a J5 ﬁtting. Hybrid concrete lines with sections of various types may also be used. 15. All basic HYDRANTULA ﬁttings (except for R3) have ﬂanges compatible with Groovelock 5½ or 4½. Some of the ﬁttings are also equipped with a Camlock 75 interface. 16. When installing structures in areas where high-slump concrete cannot be delivered (the nearest batch plant is over 90-120 min away) or local batch plants do not provide concrete of a sufﬁcient enough quality, make concrete on-site from previously brought-in materials using your own portable mixers. 17. The concrete mix proportions depend on water salinity, climate, required lon- gevity of the structure, the reinforcement quality of the formwork’s cavities, and the concrete pump’s speciﬁcations. 22

PRECAUTION 1. When drilling out binary nozzles and cuffs in Hydrantula ﬁt- tings, large-diameter hole saws from 125 to 250mm are wide- ly used. If the hole saw bites, the entire torque of the drill is transmitted to the worker’s hands, which can lead to disloca- tions and other injuries. It is recommended to use high-quality, sharp hole saws; avoid tilting. Limit the feed force to minimize the likelihood of the hole saw biting. If stationary drill presses or drill stands are available, be sure to use them. 2. When working with composite rebar, and especially when unrolling coils and cutting lengths to size, it is strongly rec- ommended to protect your hands and eyes from ﬂying glass ﬁbers and small offcuts. Contact with composite rebar leads to splinters and small, slow-healing scratches on the skin. 3. Butt welding machines, heat guns, and manual PE extruders have hot surfaces with temperatures of approximately 300°C. Unlike metal welding, hot surfaces and hot polyethylene are not distinguishable “by eye” from cold ones. Always use leath- er welder’s gloves, safety glasses, and closed clothing to avoid serious burns. 4. When assembling Hydrantula, hand-held power tools (re- ciprocating saws, jigsaws, pipe cutters, angle grinders) are widely used and are often left lying on the ground. Immedi- ately unplug power tools after use or when changing blades, drill bits, or cutting discs. 23

Do not place tools on the ground – only in special boxes or on racks. Do not use the same tool simultaneously (in turns). Do not use it in the rain! Swapping tools haphazardly, lack of personal protective equip- ment, and crowded work conditions provoke injuries! 5. When using winches, jacks, hoists, or during loading opera- tions, all “extra” workers must immediately leave the slipway. Those involved in the work must use hard hats, gloves, and safety glasses. Do not stand under a load or near loaded cables, slings, or chains! 6. It is strongly recommended not to work in poor lighting. When working in the dark, wearing high-visibility vests is mandatory. 7. When working over water or on quay walls or barges, all workers must be equipped with life jackets and water rescue equipment. 8. When using open ﬂames (gas heating torches), simultane- ous work with lubricants, solvents, degreasers, or other ﬂam- mable liquids is prohibited. 9. It is forbidden to work with unsecured (merely standing) parts of structures weighing more than 150 kg. 24

ANNIVERSARY OF UNICORN ANNIVERSARY OF UNICORN 44TH TH 11 Why HYDRANTULA Why HYDRANTULA Is a Breakthrough — Is a Breakthrough — and and Why It’s Only Appearing Now? Why It’s Only Appearing Now? HYDRANTULA permanent formwork competes directly with multiple established shoreline and marine construction methods—piles, retaining walls, sheet piling, concrete pontoons, and aluminum deck structures. What makes it diﬀerent? HYDRANTULA dramatically lowers the cost and complexity of building 3D marine concrete frames, bringing them out of the realm of oil & gas megaprojects and into reach for mid-sized developers, marinas, and residential coastal construction. So why hasn’t this «obvious» solution been around for decades? Because it wasn’t obvious—until now. Let’s ﬁgure it out. 1 1 FAQ FAQ H ydrantula is the only low-cost 3D marine concrete frame technology. Unlike piles, up to 35% of all work can be done inside workshop. And about 90% of the total work is dry. And are carried out on shore without involving heavy machinery or barges. Hydrantula installation is virtually silent and less susceptible to the vagaries of the weather. Hydrantula is almost insensitive to the type of bottom soil. 1. What are we selling? HYDRANTULA develops, manufactures and sells permanent [non-removable] formwork for casting concrete underwater or in the tide zone. The ready-to-cast concrete formwork consists of original connecting elements [ﬁttings or nodes] and beams made of regular HDPE plumbing pipes. 2. What exactly are you selling and what will need to buy separately? *We sell technology. In a narrow sense, we only sell ﬁttings = connecting nodes of the 3D frame. Beams are made from standard plumbing pipes; sea concrete, rebar and microﬁber are also widely available mass products and purchased locally HYDRANTULA FITTING CATALOGUE 2025 WHERE DOES HYDRANTULA HAVE NO ANY PRACTICAL ALTERNATIVES?
