Like their open equivalents, Enkamat flatback has a flexible three-dimensional structure of monofilaments fused together where they cross. The difference lies in the flat back produced from monofilaments in an irregular, two-dimensional structure, integrally bonded to the three-dimensional structure.

Enkamat's artificial root system provides the foundations for natural erosion protection. Enkamat flatback can have up to 2,700 m filaments per m² of mat, depending on the product type. Using this artificial root system makes it possible to safeguard many bank side areas which could otherwise not be planted.

Within flood area, and below the waterline, Enkamat flatback should always be filled with stone chippings increasing the level of erosion protection, while above the flood waterline, topsoil is sufficient. Stone chippings are retained in the mat by the filament core and the flatback structure and give a protection for medium velocity streams and rivers or on reservoir banks. When vegetation has established within the Enkamat flatback, higher velocity flow rates may be withstood.

To choose the right Enkamat flatback to suit the specific needs of your project, a design method is available, prepared by an independent body.

Enkamat will not degrade, making these anti-erosion mats the system of choice to protect slopes against erosion permanently.

Enkamat flatback comes in 1.0 m, 1.95 m, 3.85 m and 5.75 m wide rolls.
