HYDROTEX fabric-formed concrete is the top solution for lining trapezoidal channels in any facility or industry.

Looking for the best channel lining product? HYDROTEX fabric-formed concrete requires less manpower than gabions, HDPE liners, brick, PVC, soil cement, and limestone riprap. Both versatile and permanent, HYDROTEX can also be used for erosion control in canals, ditches, and open drains.

How is HYDROTEX used in concrete channel lining projects?

The Problem

An unlined channel or river is subject to bank erosion, causing the channel to encroach upon the adjacent roadway, infrastructure, or valuable property. This can result in potential collapse, costing millions in repair costs.

An unlined storm water management or irrigation channel will also allow vegetation growth, increasing waterlogging, reducing waterflow, and resulting in inefficiency of the components.

The Solution: HYDROTEX Fabric Forms for the In-Situ Casting of Concrete

Cast a concrete liner with HYDROTEX fabric forms for the in-situ casting of concrete, creating a permanent mattress that protects against bank erosion and provides protection of valuable adjacent structures or property.

With a HYDROTEX fabric-formed concrete mattress, you can manage the efficiency of water flow. You have a myriad of choices when you purchase HYDROTEX: you can line the channel with a product that can accommodate hydrostatic pressure relief, accommodate revegetation, or prevent vegetation (Uniform Section).

Best HYDROTEX Fabric Forms for Lining Channels with Concrete

HYDROTEX Filter Point

HYDROTEX® Filter Point


HYDROTEX Filter Point is one of the most popular products to cast concrete linings in channels. When pumped with fine aggregate concrete, this fabric form creates a mattress with filter points that allow the water to filter through, relieving hydrostatic pressure. Easy to install underwater and a cheaper-to-transport alternative to precast concrete block mats.


HYDROTEX Filter Band

HYDROTEX® Filter Band® Concrete Mattress


An alternative to Filter Point, HYDROTEX Filter Band also relieves hydrostatic pressure while achieving a greater reduction of flow velocity and wave run-up due to a higher Manning’s n value. Great choice for channels where a greater control of flow is required.


HYDROTEX Uniform Section

HYDROTEX® Uniform Section


Looking for a concrete slope paving alternative for your channel lining project? HYDROTEX Uniform Section fabric forms are the product for you. When pumped with fine aggregate concrete, our Uniform Section fabric forms create a rigid mattress with minimal permeability.


HYDROTEX® Enviromat®


For an aesthetic channel lining solution that will allow vegetation, prevent erosion, and help the environment, choose our Enviromat concrete linings. The fabric formwork’s revolutionary open design allows vegetation to grow in between the concrete blocks.


All HYDROTEX Products


Though these are the most oft-used fabric formworks for casting a concrete lining at channels, you can choose any other HYDROTEX product—or you can let us recommend one based on the project specifications.

Forget Traditional Concrete Lining

Concrete channel lining is the most popular erosion control method for rivers and channels.

HYDROTEX is superior to traditional concrete channel lining alternatives. Not only is HYDROTEX designed to be installed both on land and underwater, the material is cheaper to transport and the installation often requires less manpower than other labor-intensive alternatives.

What kinds of channels can HYDROTEX protect?

Roadside drainage, stormwater, irrigation, and surface water channels can be protected by a HYDROTEX fabric-formed concrete mattress.

We would recommend Enviromat, Enviromat FX, Filter Point, Filter Band, and Uniform Section for these applications, but will work with you to manufacture the best concrete mattress for your project.

Why choose us?

We are the only manufacturer of HYDROTEX permanent erosion control systems.

You’re partnering with the manufacturer, not a third-party seller or a middleman.

With Synthetex at your side, you won’t have to guess during any stage. You’ll have our support from the very beginning up until the last fabric-formed concrete mattress is pumped in place. From on-site support to design assistance, you will have invaluable resources at your disposal with us at your side.

Who is Synthetex?

We are the manufacturer of HYDROTEX® geosynthetic fabric formwork used for the in-situ casting of concrete.

We are not an engineering firm, subcontractor, concrete supplier, or fabriform installer. We are a manufacturer.

As your manufacturer, we work with each of those entities to deliver cost-effective solutions at every stage of your project. Our team will also assist with cost analyses, train installation teams, provide technical assistance, and assist with design and hydraulics.

We’re not just a one-time supplier—we’re your strategic partner for your current project and beyond.

Enviromat®

Enviromat® (EM) Concrete Linings


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.

Enviromat Linings are comprised of concrete-filled elements and unfilled areas that allow for the establishment of vegetation.  Once the concrete sets, the defined unfilled and interwoven areas are opened by cutting the fabric and are planted or are filled with topsoil and seeded.  Within a growing season a vegetated cover will normally extend over the lining, resulting in an erosion control system with the hydraulic, ecological and aesthetic features desired.

HYDROTEX® FilterBand®

FilterBand® (FB) Concrete Linings


FilterBand® (FB) Concrete Linings are similar to Filter Point, providing an effective and highly permeable concrete lining that resists erosive forces. FilterBand® differs from Filter Point in that the form creates interconnected, tubular concrete elements that are separated by large, interwoven filtration bands.  The filtration bands provide for greater reduction of uplift pressures than Filter Point Linings.  Also, the biaxial alignment of the tubular elements creates two directionally determined coefficients of hydraulic friction. As a result, FilterBand® achieves greater reduction of flow velocity or wave energy than Filter Point.

FilterBand® concrete linings are specified in situations similar to those for which Filter Point might be specified, which also require greater relief of uplift pressures, higher reduction of flow velocities, or greater reduction of wave run-up.

HYDROTEX® Uniform Section

Uniform Section (US) Concrete Linings

Uniform Section (US) Concrete Linings


Uniform Section (US) Concrete 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.  Uniform Section 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.

Uniform Section Concrete Linings are resistant to leachate and most chemicals.  They protect geosynthetic liners from mechanical damage, exposure to UV light, and freeze-thaw cycles.  These self-supporting, high-strength linings permit construction on steep side slopes and replace the conventional use of clay or sand as liner protection. Placement of the forms and concrete filling can be performed without the use of equipment on the liner.  The tensile strength and abrasion resistance of the fabric protect the liner from the pumped concrete.

HYDROTEX® Filter Point

Filter Point (FP) Concrete Linings

Filter Point (FP) Concrete Linings


Filter Point Concrete Linings with filtration points (drains) provide erosion-resistant, permeable concrete linings for ditches, channels, canals, streams, rivers, ponds, lakes, reservoirs, marinas, and protected port and harbor areas.

Filter Point Concrete 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 filtration points provide for the relief of hydrostatic uplift pressures, increasing the system’s stability.

Filter Point Concrete Linings were the first type of fabric formed concrete system developed. In 1965, a Dutch patent was issued for “fabric formed slope paving.” The form suggested by this patent was later refined to create the first “filter point” lining.
