(FR) DISPOSITIF DE SUPPORT DANS LE SOL POUR ANCRAGE DE RACINES
Abstract: front page image
(EN)In the support device in the ground (16) for turfen surfaces of flat or inclined roofs, a tridimensional hooking layer (20) comprised of interwoven fibers or hanks is solidly fixed on an anchoring mat (18) resistant to the traction at least in certain areas. The hooking layer (20) receiving and stabilizing planted grounds and grass roots has a large free volume and is preferably comprised of entangled simple plastic yarns. The anchoring mat (18) is formed as to retain the ground and is preferably water permeable, and possibly it is a moisture accumulating filtering mat. For the formation of a draining, a hooking layer (22) similar to the upper hooking layer (20) is preferably fixed to the lower surface of the anchoring mat (18).
