FilterPave® is an environmentally sound, highly stable surface cover made from recycled glass gravel.

Due to its open-pore structure, FilterPave® is able to filter precipitation water on its way into the soil. Pollutants such as motor oil, fuel residues or hydrocarbons are absorbed in the recycled glass layer and thus cannot contaminate the groundwater any longer.

Tests have revealed that up to 15 kg of oily substance can be bound per cubic metre of FilterPave® (research by the University of Wisconsin).
