Kaiserslautern, March 2021
In Legnica, Poland, Inspol employees rehabilitated a 32 m long stretch of defective concrete pipes with a diameter of 400 mm. The extremely flexible BRAWOLINER® 3D 300-400 and the BRAWO®TC epoxy resin were used.
The challenge of this installation was mainly the long stretch across 32 metres and the fact that the temperatures were quite high at the time of the rehabilitation. This requires a fast and precise procedure, as the resin reacts faster at higher temperatures. The liner therefore had to be impregnated and installed quickly – with such a long stretch, this requires experienced, professional installers who have enough experience and know about the risks. The BRAWO® TC was cured with hot water. In just eight hours, the four Inspol employees were able to declare the construction site finished again.
