Initially the house was facing water leakage issues at several locations: ceiling below the R.C. flat roof, surroundings of PVC rainwater discharge pipe and electrical conduits. It was a clear sign of a failed/worn-out waterproofing system. After our team of professionals conducted a thorough inspection, we proposed to the house owner to re-do the waterproofing system. In certain cases whereby, the old waterproofing system has failed to a huge extent, the best way to repair the leakage issues is to re-do the waterproofing.

After we have completed the waterproofing works, we carried out a 4-hour water ponding test to check against the quality of our finished waterproofing system. The water leakage issue has completed stopped.
