Time-saving mortars for drain & sewer rehabilitation
Wastewater systems have been constructed since the middle of the 19th century. Many now need rehabilitating after some 50 to 100 years of use. Some of these wastewater systems or parts of systems – pipes, manhole shafts, water purification plants, catchment basins, aeration tanks, oil and fat separators, digestion tanks and sludge settlement tanks – had suffered serious damage after only a short period of time. Since 1982 the ERGELIT dry mortars described below have been developed specifically for the repair of such types of damage. High resistance to aggressive substances is the hallmark of all of these ERGELIT products. On-site technical difficulties, such as pipes that are not man-accessible, limited working space and special operating conditions, have always been a major consideration in the development of these ERGELIT mortars.
