Kemmler Baustoffe in Freiburg has remodelled its existing building. The change of use required proof of flooding for a new water permit. Those responsible decided in favour of two retention systems made from GRAF EcoBloc Inspect smart modules. The construction pits were excavated and the two infiltration trenches installed in just eight days while the building materials trade continued to operate.
