One of the most common issues in waterproofing that keep recurring is the angle fillet. The angle fillet often occurs in toilet and bathroom waterproofing, besides balcony waterproofing.
Most of the contractor facing this issue may not be able to rectify the cause of the waterproofing. However, these contractors would just apply temporary surface waterproofing. As time passes, water seepage occurs through the angle fillet, thus causing the problem to recur.
If you encounter an angle fillet issue, it is best to engage your waterproofing specialist to fix the issue permanently. Most people may only do surface treatment. They do not fix the underlying deficiency in the cross section of the angle fillet. Hence, it usually recur, resulting in additional time and money spent to rectify this issue.
