A bituminous waterproofing membrane is used for reinforced concrete roof waterproofing. This waterproofing membrane comes on site in the form of rolls manufactures and packed in the factory properly sealed.
The specifications and safety manuals of this membranes provided by manufacturer should be read before installation process.
Fire safety and prevention is the most important while using this membrane. All inflammable materials from roofs to be removed and good roofing practices should be followed. The bituminous waterproofing membranes are unfolded on the site and laid firmly on surface with tar-based adhesives using blowtorches.
A layer of bituminous water proof membrane is laid over the structural roof which acts as a shield against the seepage of water onto the roof. Roof tiles & membrane is 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 water proof materials. Membrane should be flexible with elongation to cover any small cracks, strong, chemical & UV resistant, flexible enough to take any shape over which it is laid.
Cold bitumen emulsion is a type of asphalt product that consists of bitumen (a byproduct of petroleum refining) and water that are combined with an emulsifying agent. The emulsifying agent helps to stabilize the mixture and prevent the separation of the bitumen and water, which makes it easier to handle and apply.
