Water edge protection
When geomembranes are used to protect retention ponds or lined impounding reservoirs, they need to be protected against UV and mechanical damage, usually by a layer of soil. At, above and below the waterline this soil can be subject to erosion and sliding. On steep and long-length banks, the geomembrane itself may be subject to high forces induced by the covering layer of soil.
Coverage of geomembranes with a layer of soil can also be desirable for aesthetic reasons. However, the friction between a smooth geomembrane and soil is often too low, allowing the soil to slide off. In these cases, Enkamat provides stability and support for vegetative growth.
Geomembranes are highly vulnerable to mechanical damage and constant stress. High loads and longterm creep failure may be avoided by the use of Enkamat W or Enkamat R. The installation of these geocomposites at the intersection of the membrane and soil cover will prevent these failures thanks to their defined tensile strengths. The three-dimensional structure of the mats provide the necessary friction with the soil and enable them to act as griplayer. Enkamat is anchored in a trench at the top of the slope.
Additionally, Enka-Tex installed under a geomembrane will provide protection against mechanical damage.
In general, densily vegetated banks are important to protect wet slopes from eroding. Enkamat and pre-filled Enkamat A20 allow vegetation to grow, offer micro stability at ground level, help seeds to germinate in a protected environment and stop erosion at, below and above the waterline of retention ponds and drinking water reservoirs. The flexibility and ease of installation make these products very suitable to protect the area around culverts. Enkamat A20 offers immediate protection against turbulent water flows around the inlets and outlets of retention ponds.
To avoid sliding of the cover soil on top of geomembrane slopes, the cover soil needs to be deeply rooted by vegetation. Enkamat helps to reinforce this particular zone.
