Product Details

Rain Bloc:

Specially developed percolation shaft for stormwater management or rainwater harvesting, for controlled draining of rainwater into the groundwater.
The unique inspect rim facilitate flexible laying of inspection channels within your percolation bloc ditches.
It is already completely prefitted and only has to be installed in the tried and tested percolation block system.
The percolation blocs can be inspected easily with a push-rod camera through the opening of diameter DN 150.

The Graf Rain Bloc is a system which has been particularly designed for the rainwater infiltration and retention respectively. The structure of the modules enables a space-saving installation with minimum earth covering. The surface beyond the Rain Bloc can even be used by traffic.

The flexible, high-performance Rain Bloc is ideal for use in public and industrial areas. There are no limits on the use and design of the surface above the system thanks to its extreme load-capacity. Whether it is a parking space, works entrance or storage area – everything is possible.

The lorry-bearing design guarantees extreme load capacity thanks to its stable column structure. The vehicle loading design can bear a long term load of approx. 3.5t per m2. There are not limits on the use and design of the surface over the system.

The Rain Bloc can be installed in rows or block form, with 1 to a maximum of 10 layers, depending on the local conditions and desired storage capacity. Installing the module is easy, fast and variable. It can be installed without heavy equipment – a Rain Bloc weighs just 15Kg. The individual modules are connected using practical fast connectors.

The special construction of the Graf Rain Bloc guarantees lasting, high infiltration performance.
