Abstract (en)
[origin: WO9500569A1] The mouldings proposed include a duromeric polyurethane as a binder for finely particulate material. They have a pore volume of 30 to 50 % by vol. and a high, controllable permeability to water, the water being unchanged or only insignificantly changed after a contact time of 7 days. The mouldings preferably have the same dimensions as prior art structural panels or slabs made of solid or porous material. They are particularly suitable for use in paving paths and other outdoor areas in order to allow rainwater to drain directly into the surface.
