Abstract (en)
[origin: EP1589149A2] An open profile concrete block for green support surfaces especially for supporting vehicles on a grassed area, has a two layer construction. The upper layer is made of porous concrete extending to two thirds or three quarters of the thickness of the block and with a finer pored stronger concrete as the bottom support layer. The open profiles have a tapering cross section wider at the top, with the grasses area about 60 percent of the area of each block. The porous upper layer holds moisture and provides a grip for grass roots.
