Abstract

The membrane is made of a fibrous material and of a binder consisting of an emulsion of sulphur particles in a bitumen. The fibrous material is made of a lap or of a set of laps of nonwoven fabric or of woven fabric or of a woven/nonwoven composite, either as continuous filaments or as short fibres of a chemical compound defined in each case. The binder used allows the impregnation to be carried out at a temperature close to 130-140 DEG C, that is to say without any risk of damage to the fibrous material, and the progressive crosslinking of the binder as a result of the partial crystallisation of the sulphur prevents a migration of the binder and provides a high cohesion for the membrane. This membrane is intended to provide total watertightness in civil engineering and building works.
