Because of the multifaceted strain of underground drinking water pipes, which consist of cast iron, steel or asbestos cement, a periodic testing and regular maintenance are necessary.

But even optimal repair can’t avoid corrosion, incrustation and pitting, so that water pollution and deficits of the capacity will be the consequences. In addition the danger of pipe burst and the operational costs will rise.

The laying of new pipes can correct clear these problems, but this solution is mostly expensive and definitely costly in terms of time and place.

The pipe rehabilitation with the method of cemet mortar lining is a multisided, efficient and inexpensive method, which is the worldwide state of the technology.

The Berkel Rohrtechnik GmbH owns a machinery to do cement mortar lining for pipes with nominal diameter from 80 mm up to pipes with several meters.
