The number of extreme downpours is increasing in our country. To prevent flooding and overloading of the combined sewer by the release of clean rainwater, decoupling rainwater drainage from the sewer is becoming increasingly common. This is possible using the Rockflow infiltration system alongside or beneath roads. Thanks to the high load-bearing capacity of the innovative infiltration system, it can be installed relatively close beneath the surface of a road. This means it can also be used in areas with a high groundwater level. Another significant benefit of this infiltration system is its long life. For example, did you know that stone wool has already been used successfully for more than forty years beneath train tracks and it is still working? Furthermore, stone wool is easy to process and adapt. Will it be necessary in the future to install extra cables or pipes, for example due to the decoupling of natural gas? If so, the stone wool elements can simply be sawn or drilled through, without any loss of functionality. This makes the system totally future-proof: a significant benefit for highways authorities.
When rainwater falls on unpaved surfaces, it can usually soak into the ground. But if the rainwater falls on paved surfaces such as roads, it also has to go somewhere, which can cause serious overloading.
