Erosion control and separation for hydraulic works
Tidal fluctuations and wave action can cause major damage to coastlines and off-shore construction projects. Nonwoven and specialty woven geotextiles can be used as a filter under layer beneath stone/ rock armour. Also riprap or synthetic erosion control mats are used to control erosion by disallowing the sub grade soil particles to erode. The geotextiles prevent erosion carried off by runoff water or other erosive waters, such as waves, stream flow, etc.
The geotextile maintains the integrity of the erosion control or shoreline protection system. Typically are GeoMatt NP, TerraMatt W and TerraMatt FW used in these applications.
