Problem: This RO Water Bund had been protected with flexible membrane sheets only 5 years previously. These thick sheets had been ineffective due to the footings and frames in this bund. Reverse Osmosis is a highly deionised form of water that is very reactive to concrete. The membrane had disbonded in several areas with one of the blisters being over 1m wide. The areas beneath this bund were highly sensitive rooms and so the client wanted to avoid disruptive preparation techniques such as grinding. Adhesion trials were performed to prove the adhesion of the Belzona system.
