PCT No. PCT/EP94/02907 Sec. 371 Date Oct. 6, 1995 Sec. 102(e) Date Oct. 6, 1995 PCT Filed Sep. 1, 1994 PCT Pub. No. WO95/06783 PCT Pub. Date Mar. 9, 1995A construction element, such as a supporting element for a retaining wall, has a casing which is at least partially permeable. The casing contains a block-shaped, granulated, bulk or porous filling material. The casing has two layers including a relatively rigid grating part (GT) for strength and a relatively flexible, finer meshed netting part (NT) for containment of filling material. The casing is designed as a closed hollow body which is coupled to the filling (FL) so as to form a substantially self-supporting construction element which is completely prefabricated. |
