APPLICATION OF BONDED MEMBRANE TO CYLINDRICAL COLUMNS

A client approached Stonbury to complete a routine flood test as a part of a flood test and cleaning programme. The flood test was carried out over five days due to the roof’s size - approximately 12500M2. The flood test revealed points of ingress and internal coatings that had failed.
