Technical Data Sheets
The use PVC-P geomembranes as a waterproofing for dams is a sophisticated and safe technology to avoid important water losses due to cracks and failures in the basic construction.
Dams are constructed for different purposes, but all of them have the target to store water. In countries with sufficient water the gained water is used to produce electric energy, in dry countries the water serves as drinking water or for irrigation of agricultural areas. Loss of water always means a reduction of productivity and may even endanger the base of existence of the population.
Only earth dams had received a watertight core but a great number of concrete dams are loosing water through cracks. There are different technologies to repair the concrete face of the dam but one of the most reliable and economical is the application of a waterproofing geomembrane. The choice of geomembrane and the way of fixation for the waterproofing system is a very important issue to receive a long living water tightness of the dam.
