Drainage pipe

The seepage pipe (also land drainage or drainage line ) takes seepage water from the ground and passes it off. Catching and draining off the water can be necessary if buildings or traffic routes are to be protected from constant moisture . Both groundwater and seeping rainwater contribute to soil moisture . Drainage pipes are made of plastics such as PVC and PE as well as fiber cement and stoneware . Slotted on all sides ( fully perforated pipe, type designation: TP / totally perforated pipe ) as well as slotted top (2/3 slotted) ( partial drainage pipe, type designation: LP / locally perforated pipe ) and 1/3 slotted ( multi-purpose pipe, type designation: MP / multipurpose pipe ) Differentiated drainage lines.

functionality

The pipe wall of the seepage line is smooth or corrugated and has slots or holes through which the seepage water can enter the pipe. Around the drainpipe there is a drainage layer made of soil-stable filter material that cannot be washed out by the drainage water. If this seepage layer is dispensed with, the finest particles of seepage water carried along will gradually block the slots and holes in the seepage line and the drainage effect is lost. The line is installed with a gradient of 0.5% to max. 1% installed and leads the water either to the local drainage system or a drainage shaft . It is important to ensure that the drainage pipe is installed correctly, as errors can only be eliminated later with great expense and effort. In addition, drainage lines must be flushed out at regular intervals with appropriate devices.

Application area

Drainage pipes are used wherever drainage occurs and needs to be drained off. The use of drainage lines extends to building drainage, underground traffic area drainage and the drainage of landfill areas.
