Waterproofing with Sealing Membrane PRONIL PROMEM

Water ingress in buildings can cause significant impact on structural and safety issues. The source can be external, such as rainwater, leaky roof water tanks, groundwater, external drainages or internal, such as internal tanks and sumps, water leakages from defective toilets, bathrooms etc. The water ingress not only affects the living conditions of the occupants but also the structural integrity of the building itself. Hence it becomes imperative to ensure the building structure is well protected to prevent the entry of water into the buildings.

To avoid water ingress, and to keep your building protected, waterproofing with a sealing membrane is important. The challenge is to find a product that delivers durable waterproof protection which can be applied in different structural parts of buildings. One such product is PRONIL PROMEM. It is a sealing membrane made of polyethylene foil, two-sided polypropylene and non-woven laminated.
