Porous concrete offers an environmentally friendly alternative to light traffic pavement applications. Porous concrete is generally used as an initial drainage system to absorb most, if not all, of a catchment runoff. This relieves the pressure on storm water drains and can reduce the need for kerbing and expansive storm water systems which can help to reduce stormwater infrastructure costs. Porous concrete also helps filter stormwater runoff by capturing all pollutants and filtering them through the sub-base and soil instead of pollutants flowing to downstream water bodies. By filtering the runoff this recharges underground water tables and recharges local vegetation water supplies by allowing the water to be soaked up in the immediate catchment area. Porous concrete is used for light traffic applications such as foot paths, traffic islands, driveways and car parks. Porous concrete drains standing water increasing safety whilst driving by reducing aqua planning and light glare.
