Abstract (en)
[origin: WO2013181685A1] The invention relates to a drainage system for draining away liquid from a surface including a base installed below the surface and a first and second wall. The first and second wall each extend from the base at an acute angle towards one another, defining an opening. In use the base, first wall and second wall form a conduit and liquid can drain into the drainage system through the opening and drain away along the conduit. The configuration of the drainage system assists to maintain the drainage system in place in the surface and acts against deformation from downward forces. The invention also relates to a mesh, grate or other covering for the base, first wall and second wall.
