Flat Roof Waterproofing

Leaking flat roofs are a dire problem in South Africa, where professionals and contractors are faced with the dilemma of leaking flat roofs or low sloped roofs due to pooling of water and ineffective waterproofing.


Balconies are one of the most common sources of water leaks which can lead to structural damage. The biggest problem being most waterproofing products can't withstand movement and cracks in the substrate.
