THE PROBLEM
Five vacuum pot chambers were experiencing water ingress around pipe penetrations. This was causing the system to be overwhelmed damaging equipment and wasting energy.
SOLUTION
We proposed a multi stage waterproofing solution. Initially resin injection packers were carefully installed to penetrate through the chamber walls. These were drilled and installed perpendicular to the wall rather than at 45 degrees to the leak in order to remove any chance of drilling into the plastic pipes.
These packers were then injected using Normet Tampur 125. This fast acting polyurethane injection resin rapidly seals off active leaks. As can be seen in the photos and video there was a clear pathway for water to ingress when the water table is high.
Once sealed the area surrounding the pipes was prepared by method of vacuum controlled diamond grinding. This was followed by the application of Remmers Kiesol and Remmers Sulfatex grout to ensure good adhesion to the damp substrates.
Following cure of the Sulfatex the pipes were abraded using papers prior to the application of Remmers MB2K. Remmers MB2K is quite unique in that it will bond to plastic pipes if they are abraded. The material also remains flexible and can withstand a negative water pressure, making it ideal for this application.
Remmers MB2K was applied in three coats incorporating a reinforcing bandage at the pipe/wall interface for additional strength.
These waterproofing works resolved the water ingress into the vacuum pot chambers, protecting our clients equipment and saving them energy.
