Torch on Waterproofing
Bituminous products are perfect for the waterproofing of roofs on buildings, they move with the structure and they are not too rigid and do not absorb water. Waterproofing membranes systems are designed to protect both residential and commercial buildings through a mixed substance made up of organic liquids that are highly sticky and viscous. Bitumen is a hydrocarbon and is created naturally from crude oil, it is a useful carbon store and does not generate greenhouse gases.
Torch-on membrane is a bitumen-based waterproofing product which is heat-fused to underlying substrates. It is sold in a variety of thicknesses with single or dual re-inforcement with polyester or fibre glass.
Typical uses are:
- Concrete roofs are not watertight on their own. The conventional waterproofing system with membrane is not the answer to your leaking concrete roof. The only way to do proper waterproofing on your concrete roof is to do the Torch on waterproofing.
- Torch-on is applied to flat smooth surfaces. A flat roof can be made out of a number of different materials, but the most popular include corrugated or IBR sheeting, a solid concrete slab and wood. One thing all three types of roofs have in common is that they all need to have a slight slope from back to front, or vice versa, so that rainwater can run off. However, unlike normal angled roofs, flat roofs tend to be susceptible to leaks and therefore need to be waterproofed and well-maintained to avoid this weakness
