Percolation systems


Infiltration tunnels

Installations for the discharge of treated water when there is no suitable place nearby to remove them. You can insert a hassle free purified water into the ground through infiltration tunnels.

Percolation tunnel has been especially designed for use in private and rural areas. The system, consisting of one or more tunnel modules and two end plates, can be freely sized. It is laid on one level. The lightweight is very easy to lay at only 11 kg. In order to facilitate free design of the surface above, the system can be permanently loaded with approx. 3.5 t per sqm and thus, it is suitable for vehicle loading.

Suitable for vehicle loading The system has a permanent load-bearing capacity of 3.5 tons per sqm, which facilitates free design of the surface above and thus, it is suitable for vehicle loading.

High storage volume The percolation tunnel 300 can hold 3 times the volume of a conventional gravel ditch. 1 module (11 kg) replaces approx. 800 kg of gravel and 36 m of drainage pipe.

Easy to install Installing the module is easy, fast and variable. It can be installed without heavy equipment - a percolation tunnel weighs just 11 kg. The individual tunnel modules are simply put together in one row and are equipped with two end plates per row.

Infiltration blocks

A flexible and efficient system for infiltration units primarily for public and industrial facilities. Its high resistance to mechanical loads, thanks to the area above it just does not have the use of the limits.

The flexible, high-performance percolation bloc is ideal for use in public and industrial areas. The percolation bloc guarantees extreme load-bearing capacity thanks to its stable column structure. With an earth covering of 800 mm, the lorry-bearing design can take HGVs (SLW 60). There are no limits on the use and design of the surface over the plant. Whether it is a parking space, works entrance or storage area – everything is possible.

High-performance The lorry-bearing design guarantees extreme load capacity thanks to its stable column structure. The percolation module can bear 10 t per sqm (SLW 60 capacity possible for low traffic roads) with a covering of 800 cm of earth. The vehicle loading version can bear a long-term load of approx. 3.5 t per sqm. There are no limits on the use and design of the surface over the plant. Whether it is a parking space, works entrance or storage area – everything is possible.

High storage volume The GRAF percolation bloc 300 can hold 3 times the volume of a conventional gravel ditch. 1 module (15 kg) replaces approx. 800 kg of gravel and 36 m of drainage pipe.

Easy to install Installing the module is easy, fast and variable. It can be installed without heavy equipment – a percolation bloc weighs just 15 kg. The individual modules are connected using practical fast connectors.
