Bituminous Waterproofing

A bituminous waterproofing membrane is used for reinforced concrete roof waterproofing. This waterproofing membrane comes on-site in the form of rolls manufactured and packed in the factory properly sealed.
The specifications and safety manuals of this membrane provided by the manufacturer should be read before installation. Fire safety and prevention are the most important aspects of using this membrane.
All flammable materials from roofs are to be removed and good roofing practices should be followed.

The bituminous waterproofing membranes are unfolded on the site and laid firmly on the surface with tar-based adhesives using blowtorches.
A layer of bituminous waterproof membrane is laid over the structural roof which acts as a shield against the seepage of water onto the roof. Roof tiles & membranes are applied over the filler material laid to slope to pass the flow of water into drains. A proper slope is necessary to allow the water to flow steadily to drains.

These membranes have 2 to 4 mm thick waterproof materials. The membrane should be flexible with an elongation of 150 % to cover any small cracks, strong, chemical & UV-resistant, and flexible enough to take any shape over which it is laid.
