Drainage system with porous flexible material paths - has paths linearly connected to form mat containing tubes filled with fluid resistant bodies

摘要

The drainage system has two porous and flexible material paths (1, 1a), in a network. these may be intersecting chemical fibres or metal fibres, resistant to salts, acids and similar components in the soil. these paths, at the manufacturing point, are linearly connected to form a mat (6). This mat has tubes (2) which extend in a parallel fashion in the transverse or longitudinal direction of the paths. The tubes are filled with fluid-resistant bodies which have a many times greater minimum cross-section than the pores of the tubes. The mat (6) is arranged vertically along a house foundation (9) with vertical tubes. the bottom part of the mat covers a soil filling (12), such as macadam.
