Waterproofing

Waterproofing is the process of making an object or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths.

The APP membrane, short for Atactic Polypropylene Membrane, is a special waterproofing material that is manufactured from Bitumen. With proper workmanship, the APP membrane is a very efficient and durable waterproofing material used in most constructions. It is a waterproofing material used on concrete flat roofs (which are still roofs) or roofs with low pitch. Apart from concrete roofs and low pitched roofs, other areas of application are concrete gutters, basements and retaining walls
