Abstract
A layered architectural water pervious concrete is provided. The concrete assembly includes a first layer of water pervious concrete preferably having 15%-25% void space capable of channeling water to the ground and underlying water table. Poured upon the pervious concrete layer, is a non-pervious concrete layer. Joints are formed through the non-pervious concrete layer, which preferably penetrates into the pervious concrete layer at least ¼ inch. Water flows from the top surface of the concrete assembly through the joints and into the porous concrete layer for distribution to the ground below.
Claims9
A method of producing a layered architectural pervious concrete, the method comprising the steps of:
- (a) preparing a subgrade for receipt of a poured concrete mixture;
- (b) pouring a pervious concrete mixture upon the subgrade to form a layer of pervious concrete and create a pervious concrete surface;
- (c) after the pervious concrete mixture has been poured upon the prepared subgrade, pouring an impervious concrete mixture upon the pervious concrete surface to form a layer of impervious concrete and create an exposed impervious concrete surface, and wherein the pouring of the impervious concrete mixture upon the pervious concrete surface is conducted while the pervious layer of concrete is still in a plastic state;
- and
- (d) forming one or more joints into the layer of impervious concrete with the one or more joints extending at least from the exposed impervious concrete surface to the pervious concrete surface.
