Flexamat Permanent Erosion Control

Flexamat is a permanent erosion control mat used for stabilizing slopes, channels, low water crossings, inlet/outlet protection and shorelines. 6.5" x 6.5" blocks, locked together with 1.5" spacing give the mat flexibility and allows for optional vegetation growth.

Flexamat Applications



Flexamat consists of concrete shapes, locked together with a high strength, polypropylene geogrid. There are openings around each concrete block that give Flexamat the flexibility and enable it to be packaged in rolls. The openings also allow vegetation to grow through the mat. Eventually, vegetation will completely cover Flexamat. It can be manufactured with various backings such as non-woven fabric to stop vegetation growth or a TRM (turf re-enforcement mat) depending on the soil conditions and other factors.

There's a wide range of applications where Flexamat is utilized, but it is most commonly used for erosion control. Flexamat is used to control erosion in channels, outlet protection, on slopes, for shoreline protection and many other applications.

Departments of Transportation

Using Flexamat for erosion control along roadways improves safety. Safe shoulders are protected from becoming
steep drop-offs dangerous to motorists, cyclists, and pedestrians. Unlike rock rip rap, Flexamat may be safely driven
across. Rocks cannot be thrown into traffic. Flexamat can be safely walked by both pedestrians and wildlife.


Inlet & Outlet Erosion Protection

Flexamat is the best solution for inlet and outlet protection at storm water pipes. Flexamat is an excellent replacement for RIP RAP because it is safe for pedestrians, will not damage mowers or other maintenance equipment, blocks cannot be dislodged or thrown like stone. Additionally litter cleanup is considerably easier and safer than RIP RAP or concrete channels.

Energy Erosion Protection

At solar sites, Flexamat provides locked in place protection for drainage around the solar panels. At oil and gas drilling pad sites, Flexamat is used for armoring perimeter ditches, letdown structures, spillways, and as perimeter runoff dissipation.
Pipelines are susceptible to exposure caused by erosion. Flexamat is utilized as a permanent armor providing
erosion protection for high pressure pipelines.


Mat Width & Length: Manufactured in standard widths of 4', 5.5', 8', 10', 12, & 16'. Lengths can be cut to order per project requirements. Stocked lengths are 30', 40', & 50'. 4' x 4' mats stacked on pallets are also available.

Underlayment Options: Standard Flexamat is manufactured with Curlex II underlayment backing. It may also be manufactured with Recyclex® TRM or non-woven filter fabrics. Onsite conditions and project requirements determine the appropriate underlayment material. 

Weight per Square Foot: 10 lbs per square foot.

Block Size: The concrete blocks are 6.5" x 6.5" x 2.25". There is 1.5" spacing between the blocks.

Limiting Shear: 24+ PSF (non vegetated)

Limiting Velocity: 19+ft./second (non vegetated)
