How it works
The drainage layer is to absorb and distribute rain and to lead it to the drains. As this layer in the sports ground is located directly below the turf-bearing layer, the drainage layer is not to be built from slag or other materials that are hostile to vegetation.
Nowadays the grain size in the drainage layer is adjusted to the grain size of the turf-bearing layer. The maximum grain size should not exceed 32mm. As for the filling of the drainage, equal grain distribution and therefore appropriate stability and filter quality are of great importance. Every material our company uses is tested by our certified laboratory partners before use.
The drainage layer is installed with a tracked vehicle that operates backwards. Only tracked vehicles are to drive on the drainage layer during installation. We use tracked vehicles with chains for soft ground and completely automatic laser control to keep ground pressure to a minimum. Completely automatic laser control ensures that the roof pitch is exactly 0.8 % on the entire sports turf area.
Why we are ahead
The installation of drainage layers is just another part of the entire product for us as a system provider. Experience, technology, good suppliers and regular laboratory tests foster our competitive lead regarding the foundation of sports facilities.
Evenness, layer thickness & slope
The laser-controlled installation of the drainage layer ensures that the layer thickness is ensured at constant slope. Furthermore, laser control reliably avoids unevenness.
Consistent compaction of the drainage layer is crucial for guaranteeing water permeability. Therefore we only install drainage systems with tracked vehicles.
Water permeability & Frost resistance
We check for every individual case that water permeability according to DIN 18035-5 and resistance against freeze-thaw according to DIN EN 1367-1 is guaranteed.
The working speed that we are famous for is achieved through advance planning, optimised processes and cutting-edge technology.
We only use tested material for our drainage layers to avoid any problems whatsoever.
Our laboratory partners support us in assuring material quality. Therefore, the decisive parameters are checked for every individual project to ensure that we achieve the highest quality possible for every individual component.
