Torch-on bitumen is a relatively common form of bituminous membrane for waterproofing, but not an easy installation for the uninitiated.
We take a look at what’s involved, when torch-on bituminous membrane is most suitable and why it is an optimum choice for long-term and effective waterproofing solutions.
What is torch-on membrane?
Torch-on is a flexible membrane containing bitumen and a variety of polymers. It contains asphalt in one of two forms: Styrene Butadiene Styrene (SBS), a rubber modified asphalt, or Atactic Polypropylene Plastic (APP), a plastic modified asphalt.
Torch-on bitumen, as its name suggests, is a heat-activated bituminous waterproofing membrane that’s applied to the surface using a blow torch. We then add a layer of polymer to enhance structural integrity. Membrane edges are also bonded with heat, giving us the flexibility to cut and shape it to fit any space.
APP is quicker to install but less flexible and hardwearing than the SBS type of torch-on. SBS requires a longer installation process as it takes longer to heat. It is very flexible however and has a very long life span. Both types of torch-on installation are non-toxic and non-carcinogenic.
Torch-on benefits and best applications
Torch-on bitumen waterproofing membranes are robust and durable, with UV and heat-reflective properties. Additional benefits include guaranteed membrane thickness, double thickness, long-term durability, vapour distribution base sheets and root-resistance.
Torch-on membranes are also non-water soluble so suitable for very damp or submerged areas such as basements, tanks and swimming pools.
At Danrae Group, we frequently recommend torch-on membranes for projects ranging from luxury apartment blocks to watertight planter boxes. And we find they can be a good option for flat roofs, which are more susceptible to storm damage, extreme weather and blockages, that impact adequate drainage.
