Graf - Stormwater Management

Product Knowledge

The flexible and high-performing Percolation Bloc 300 is particularly suitable for the application in public and industrial areas. It can be used for the drainage of roofs, squares, roads and industrial real estates. Thanks to its solid column design, the Percolation Bloc 300 even bears extreme loads. It is lorry-bearing with 80 cm (31.5 inches) earth covering and offers therefore unlimited possibilities of use for the surface beyond: for example, the Percolation Bloc 300 can be built in below parking areas (SLW 60-compatible) and storage spaces.
