<p>The mattress has a layer made of a geological substrate and provided between outer layers, which are made of geo-plastic. An upper layer has a rough three dimensional structure such as wire of non-plastic filaments. An outer side of an upper barrier layer exhibits a spatial structure and a high-low structure in a type of hump or combs. The geological substrate is made of gravel, stones and bricks and displaced with a biogenic material such as dead wood, bark pieces, cones, moss and part of clay pellet. The mattress is divided into longitudinal compartments (1). An independent claim is also included for a method for horizontal filling of an erosion protection mattress.</p> |
