Construction of a slope with vegetated facing is made easy with the use of TenCate Polyfelt® PEC high strength composite geotextile and erosion control geosynthetics. Suitable for slope angles up to about 60° and multiple berm heights, this construction method uses TenCate Polyfelt® PEC as the reinforcement in the soil backfill and erosion control geosynthetics placed on the surface of the slope. The system also allows the use of on-site soil backfills (usually with poor drainage properties) as the composite geotextile enables in-plane drainage.
The wide range of erosion control geosynthetics available from TenCate such as TenCate Polyfelt® Polymat EM and TenCate Polyfelt® Envirofelt CF are ideal for promoting vegetation growth. They retain topsoil and provide optimum conditions for seed germination that result in rapid vegetation coverage on the slope surface, protecting it against long term soil erosion.
This proven system is a preferred choice for designers and contractors alike because of the easy and rapid construction technique, and its cost effectiveness.
