PM 20 is a high-performance drainage membrane and represents the ideal solution for the drainage of rising water, seepage water and backwater. It offers the drainage capacity of conventional dimpled membranes many times over.
The dimple height of 20 mm offers an enormous drainage capacity of approx. 9 l/s·m.
The pressure resistance of approx. 180 kN/m² ensures a high level of security and corresponds to a compressive strength of 18 t per m2.
Accumulated water can then already be drained in the shell construction phase.
This way, any water that accumulates as the groundwater level rises is securely discharged into the drainage line, where it can be pumped out.
