Drainage mats (also drainage mats, drainage systems, surface drains) have the task of reliably draining excess water to the corresponding drainage systems and thus avoiding waterlogging within the components. Drainage systems are used in flat roof systems with and without green roof structures, façade structures as well as in the area of terraces and balconies and the foundation.
Drainage (also drainage / drainage) are measures and systems that collect water on and around buildings and drain it away in a targeted manner. They are available in the form of drainage mats, pipes and entire systems.

Stratified water and stagnant leachate exposed to stratified water and floor slabs in contact with the ground must be protected with a drainage system in accordance with DIN 4095.
For buildings with a floor area of more than 200m², additional drainage pipes are required, which must be connected to the ring drainage and drained.
