APP Membrane Waterproofing
At Converge Constructive, we specialize in APP (Atactic Polypropylene) Membrane Waterproofing, one of the most trusted solutions for protecting structures against water leakage and weathering. APP membranes are made from modified bitumen and reinforced with polyester, making them flexible, durable, and resistant to UV rays and extreme temperatures.
This waterproofing method is highly effective for rooftops, terraces, podiums, basements, water tanks, and industrial structures, ensuring a long-lasting barrier against seepage and cracks. With our expert installation, your property gets reliable protection and extended structural life.

Our PU Coating Waterproofing Process
1
We clean the surface thoroughly, removing dust, loose particles, and debris. Any cracks or uneven areas are repaired for a smooth base.
2
A bitumen-based primer is applied to improve adhesion between the surface and the APP membrane.
3
High-quality APP sheets are rolled out and carefully aligned. They are then bonded to the surface using a torch-on method, ensuring strong adhesion.
4
All overlaps and joints are sealed with precision to form a continuous, seamless waterproofing layer.
5
If required, a protective screed or insulation layer is added over the membrane to prevent mechanical damage and increase durability.
6
We carry out a detailed check to ensure there are no gaps, weak points, or imperfections in the membrane installation..
