STORMWATER MANAGEMENT
FM Environmental Stormwater Management
Stormwater is the phrase used to describe the excess rainwater that flows from rooftops, roads, car parks and other buildings. This water can contain many pollutants picked up from roofs and highways. In extreme weather conditions sudden heavy downpours of rain can cause major environmental disasters. Using our range of products; storm water cannot only be safely removed, but it can be stored and recycled for commercial and domestic use.

The newly developed GRAF Percolation Bloc, which was specially developed for retaining or percolating rainwater, is particularly advantageous. The Percolation Block has been awarded with the “Product of the Year 2002” prize.

It facilitates quick installation without heavy equipment and without gravel. Thanks to its good stability it can also bear heavy lorries. Can be installed anywhere. Percolation Blocs can be arranged next to or on top of one another as desired. As the Percolation Bloc can store 95 % of its volume of rainwater, only a 1/3 of the volume needed for a gravel trench is required. This means less space is needed and installation costs are lower.
