HYDROTEX® Fabric Formed Concrete Solutions

Synthetex’s HYDROTEX Fabric Formed Concrete solutions are used to construct a wide range of systems that provide outstanding performance in erosion control, scour protection and repair, foundation, environmental and marine construction applications. HYDROTEX linings are installed by positioning fabric forms over the areas to be protected and then pumping high-strength, fine aggregate concrete (structural grout) into the forms. The concrete lining can be placed either underwater or in-the-dry. The high-strength, fine aggregate concrete is used in place of conventional concrete because of its pumpability, strength, density, and absorption resistance.

HYDROTEX Products

Filter Point (FP)

Filter Point Linings with filtering points (drains) provide erosion resistant, permeable concrete linings. Filter Point Linings have a cobbled surface and a relatively high coefficient of hydraulic friction in order to achieve lower flow velocities and to reduce wave run-up. The filter points provide for the relief of hydrostatic uplift pressures, increasing the system's stability. (learn more)

Articulating Block (AB)

Articulating Block Mats form cable-reinforced concrete block mattresses that resist erosive forces. They are often constructed where a revetment is exposed to frontal attack by wave action. AB Mats are typically used to protect coastlines, canals, rivers, lakes, reservoirs, underwater pipelines, bridge piers, and other marine structures from propeller wash, ship wakes, wind waves, currents, and high velocity flows. They are also used in environmental construction for landfill caps, down chutes, and collector channels. (learn more)

Uniform Section (US)

Uniform Section Linings are similar to traditional concrete slope paving. They create a solid, high-quality concrete lining with a relatively low hydraulic resistance and uniform cross section. These linings are used to reduce the infiltration or exfiltration of aggressive waste and chemical fluids into or out of open channels and basins. They are also used to reduce exfiltration in arid regions where open channels and basins require watertight linings. (learn more)

Filter Band® (FB)

Filter Band Linings are similar to Filter Point, providing an effective and highly permeable concrete lining that resists erosive forces. Filter Band differs from Filter Point in that the form creates interconnected, tubular concrete elements that are separated by large, interwoven filter bands. (learn more)

Enviromat® (EM)

Enviromat Concrete Linings are installed to provide protection against periodic high flows. After installation, vegetation can be planted within the open structure of the lining to create a more natural appearance. Enviromat Concrete Linings are used in drainage ditches and on the upper slopes of channels, canals, lakes, reservoirs, rivers, and other water courses as well as for embankments subject to heavy run-off. (learn more)

HYDROCAST® (HC)

HYDROCAST fabric formworks provide a low cost in situ concrete alternative to natural rock and precast concrete where they are not possible or practical, cast in-place, concrete armor units and structures eliminate the need for cranes. (learn more)

Pile Guards (PG)

HYDROTEX Pile Guard Fabric Formed Concrete systems are available in lengths and diameters designed to armor your steel, concrete or timber piles with custom solutions and not be restricted to the standard diameters. (learn more)

Grout (Concrete) Bags (GB)

HYDROTEX fabric forms provide an effective forming system for casting large concrete armor units in place, underwater or in-the-dry. Fabric formed concrete armor units meet the requirements for a reliable and economical cast-in-place alternative to heavy quarry stone (rip-rap) or large precast concrete blocks. They are used for the construction and repair of erosion control structures such as dam scour aprons, breakwaters, dikes, seawalls, groins, and jetties as well as other hydraulic and marine structures.

Subsea Formworks (SF) (PG)

Fabric formed concrete supports, mattresses, covers, sleeves and shells are used to prevent pipeline damage and scour, and support pipeline freespans. Jack-up supports can be used to raise a pipeline or structure. The flexible, high-strength synthetic woven fabric bags are cost effective to make and are easy to deploy by ROV or diver. (learn more)
