Embankment of rock granulations for dissipating and draining of precipitation water on flat roofs and at splash-water bases has rock granulation bound to laminar main body with organic binder only through contact surfaces

摘要

Embankment of rock granulations on flat roofs and at splash-water bases has rock granulation bound to a laminar main body with an organic binder only through the contact surfaces. The grain size amounts 8 mm - 2000 mm, preferably of 16 mm - 200 mm. The individual grains are interconnected via organic binder e.g. polyurethane, epoxy, acrylate, polyester or latex.
