Percolation block
GRAF

* Specially developed percolation shaft for stormwater management or rainwater harvesting, for controlled draining of rainwater into the groundwater
* There are no limits on the use and design of the surface above the system thanks to its extreme loadcapacity
* Whether it is a parking space, works entrance or storage area – everything is possible
* It is already completely prefitted and only has to be installed in the tried and tested Rain bloc system.
* Lorry-bearing with 50 - 275 cm of earth covering
* It facilitates SLW 60-bearability with an 50 cm (19.7 inches) earth covering
* Max. installation depth 500 cm to the lower edge of the Rain Bloc

Rain Bloc inspect:

* The unique inspect rim facilitates flexible laying of inspection channels within your Rain bloc ditches
