Uses of torch on waterproof membranes


Building waterproofing solutions like torch-on membrane waterproofing are made of bitumen and other modified polymers. When used on a structure’s surface, it stops moisture and fluids from penetrating, which, if disregarded, may eventually harm a building’s structural integrity.

This kind of waterproofing in building construction is a sheet membrane system that provides a very efficient waterproofing solution for roofing and other surfaces that suffer ponding (when water gathers on a flat surface), since it neither gets damaged nor allows seepage to occur.

Torch-on waterproof membranes come in two different varieties:

Polypropylene Actif Plastic modified asphalt (APP) is the ideal material for anyone searching for improved sun and UV radiation protection since it is made of elastic plastic that can withstand high temperatures. In comparison to SBS sheets, APP melts more quickly when heated with a torch.


Butadiene Styrene Styrene, often known as SBS, is constructed of asphalt that has been rubberized, making it more elastic than APP. It is more adaptable in colder climates and does well with changing weather, temperature, and even stressors from contraction and expansion.

Consult with a knowledgeable building waterproofing service provider to verify that the waterproof membrane will endure the test of time if you are unclear which is ideal (there are undoubtedly benefits to picking the appropriate one).

Can torch-on waterproofing membranes be applied anywhere?

It is feasible to employ a torch-on membrane system for industrial, commercial, and residential purposes. Flat roofs, balconies, and even planter boxes, where water collects often, are particularly waterproofed with it. Additionally, they are beneficial for below-grade and basement applications because they provide an impermeable, high-quality, long-lasting, waterproof barrier that seals off these often uncontrolled places. They are therefore ideal for low-maintenance, challenging-to-access areas like your subterranean rooms and basements.

In Australia, torch-on membranes are often used to the following:

  • Basements, tanks and tank linings, underground parking garages, flat roofs, terraces and balconies, slabs and foundations for buildings
  • Below-grade buildings’ walls and connections
  • Used as a sealant to patch up holes in roofs, fissures, and other structural problems.

Why select torch-on membranes for waterproofing?

For a structure to last a long time and be safe, it must be waterproof. After all, moisture has the potential to seriously harm a building. In terms of health, leakage may result in the growth of mould and germs, which is dangerous for anybody working or living inside a building.

Depending on where the leak is, it may also damage interior areas or electrical components. Corrosion brought on by moisture over time may endanger a building’s structural integrity and safety.

Several advantages of torch-on membrane waterproofing technologies include:

They may be utilized completely submerged, and if properly installed, there should be no leakage problems at all. Additionally, they may be used to seal flower boxes and gutters. Torch-on membranes are among the most durable waterproofing options now offered, according to qualified building waterproofing engineers.

Torch-on membranes work well as insulation. For example, their presence on the roof provides another layer of the sheet that will aid in controlling a building’s temperature. In addition, they (especially APP) aid in shielding the surface from the sun’s damaging rays.

Waterproof membranes that are torch-on are a sustainable option for roofing. They not only shield the roof from the impacts of rain and cold weather, but they also lessen the carbon footprint of a structure.

They are popular among contractors because they endure a long time and often adhere to international waterproofing requirements. Think of them as a wise investment that will result in a structure that is more durable and sustainable.

Who can you trust with the installation of torch-on membranes?

Torch-on membranes can only be installed by experts. A novice builder won’t lay them straight or permit the necessary turnups or overlaps to provide a tightly bonded and waterproof solution.

If you’re searching for a team to assist you with your waterproofing requirements, go with a business that has experience in designing, installing, and repairing torch-on membranes.
