Abstract: A support fabric for bulk goods which contains synthetic warp yarns interwoven with weft yarns, said warp yarns being form from straight warp yarns and from binding warp yarns, each of the straight warp yarns having a higher strength than the binding warp yarns and the construction being such that on exposure of the fabric to a tensile force in the warp direction the straight warp yarns absorb a significantly higher propor- tion of the tensile force than the binding warp yarns, wherein according to the invention a sufficiently large proportion at least of the straight warp yarns consists of polyester, a sufficiently large proportion at least of the straight warp yarns consists of at least one other polymer, the breaking elongation. of the straight warp yarns made of polyester is significantly less than that of the straight warp yarn made of another polymer, and the long-term stability of the straight warp yarns made of another polymer to highly concentrated acids or alkalis at 35°C is significantly higher than that of the straight warp yarns made of polyester, an which is preferably used for supporting waste material such as domestic waste, industrial waste, sludges and the like on old landfills or similarly soft ground.
