Product range
All products are of exceptionally high quality, stability and are extremely flexible for many applications, are TüV certified and have a 50-year lifetime warranty.
Buildings with the associated paved surface are increasing, making it difficult for rainwater to find its way. More and more water ends up in the sewage system. To prevent the sewers and water treatment plants from being overloaded, rainwater must be collected separately. The infiltration crate protects the sewer from rainwater.
The rainwater ends up in the infiltration crate via the infiltration system. The infiltration crate must be mounted with the top at least 30 centimeters below the ground.

Calculating infiltration crates
At HTW Treerootsystems you can order various infiltration crates from the IT Plus brand. The correct number of crates of a certain size that you should use depends on the number of square meters of paved surface and the amount of precipitation in millimeters that you have to store. You can then calculate the number of infiltration crates.
We show you an example of a calculation: Approximately 20 liters of rainwater fall per square meter of paved surface. If you have a paved surface of 100 m², you need a capacity of 100 m² x 20 liters = 2000 liters. You can then opt for packed crates of 200,600 and 1000 litres. Or you can put them together yourself and pack them with geotextiles.
