Abstract

Combination of a three dimensional mesh or coarse undulating fabric and a layer of plain fabric is claimed for use for sub-soil drainage. The plain fabric acts as a filter and the interstices of the coarse layer provide the water channels. More versatile than porous pipes, etc., the semi-flexible sheet drain can cover wide areas, follow ground contours and is less susceptible to choking. Pref. the mesh is made of a plastics (PVC or polypropylene) material, e.g. in the form of crossed arrays of rods linked by posts or strips or as a coarse undulating fabric shaped by continuous thermoforming. Pref. the filter layer comprises a non-woven fabric made from continuous synthetic polyolefin or polyester filaments. Opt. the opposite face of the drain may be covered with a flexible plastics film. Drainage mat can be stored rolled prior to use for agriculture, buildings, roads, civil engineering, etc.
