The GRAF Rain Block is specifically designed for rainwater soak-off in large industrial areas and public places such as car parks. Immersible blocks can be used to create very large reservoirs below ground level while maintaining good soil bearing capacity.
Immersion blocks can be installed in the soil in rows or in layers. A maximum of five layers can be stacked, but the final number will depend on the ground, the application and the expected capacity.
Weighing just 15 kilograms per block, it is easy and convenient to install. The blocks are connected to each other by means of quick fasteners.
