Abstract (en)
[origin: EP0952257A2] The module (10) comprises: a mass (11) of loose, relatively small and light solid objects, such as to define a body with drainage properties comparable to or better than gravel, a fibre layer (15) covering the mass of objects and possessing filtering properties such as to enable water to pass but to retain earth particles, and a metal mesh cage (21) able to retain the mass of loose objects together and to give the module a constant determined geometrical shape. <IMAGE>
