Geotessile per il controllo erosione
TERRAM NP TERRAM

Natural vegetation can provide a certain level of erosion protection, it is often inadequate on steep slopes or areas prone to wave run-up or intermittent high velocity flows. This can occur in coastal areas, rivers, lakes, reservoirs, drainage ditches, flood bunds and overspill ponds.

River and canal banks are subject to wave action creating reverse flow conditions, it is this dynamic erosive force that undermines bank stability and affects channel flow and navigability.

The hydraulic and filtration properties of Terram Geotextiles allows them to be highly effectively when used in place of traditional filter layers. Typically, a single layer of geotextile fabric can replace a succession of stone filter layers. A single bedding layer of stone is laid on the geotextile, to carry the rock armour that resists erosion caused by variable hydraulic forces.
