How it works
The drainage pipes that run along the ground, so-called vacuums, are installed with a slight slope. They transport the rain water to the collectors running alongside the ground. The collectors transport the water to a sewer, drainage or central infiltration ditch.
Installation
The drainage trenches are cut into the ground with a slight slope by means of a laser-controlled trencher. Then the drainage pipe is put into the trench. Afterwards the trench is filled up with filter stable gravel up to the lower edge of the drainage layer.
We use a special-purpose machine built by ourselves for filling up the drainage trenches which ensures that the drainage pipe is located in the middle of the trench, therefore entirely surrounded by filter stable material.
In the last step, the trench is compacted to avoid settlement later on. In order to avoid silting, we only use gravel that was tested for filter stability.
WHY WE ARE AHEAD
Technology
All components of our total system are optimized and adjusted to one another so we can guarantee our customers long-time quality of their sports facilities. Especially regarding foundation and drainage we enjoy a big advantage regarding quality compared to many of our competitors who are not in a position to operate as system providers.
Slopes & elevations
The exact elevation and the exact slope of the drainage system are decisive for water drainage. Three factors influence precision: The trencher, the laser control and the precision exercised during work.
Selected materials
The drain materials used are tested for sufficient water permeability to avoid insufficient water drainage and silting of the drainage.
Compaction
Sufficient compaction of the drainage branches is crucial for the quality of the sports ground as settlement would lead to unevenness.
