Abstract (en)
[origin: EP0307541A2] A drainage mat comprising a three-dimensional openwork covered on at least a major surface with a water permeable fabric (1), said fabric having a permittivity from 0.2 sec-<1> to 2.0 sec<-><1> and exhibiting a dynamic permeability after 10<6> loadings of at least 10<-><4> cm per second. Preferably the mat is elongate, bendable and has a rectangular transverse cross section, and comprises a polymeric core (2) enveloped by the water permeable fabric (1), said core having a plurality of substantially rigid fingers (4) extending from one side of a layer (3).
