Torch on bitumen waterproofing has been a waterproofing membrane in Australia since 1940. Known today as "Torch on", this waterproofing membrane is highly effective and extremely durable for our Australian climate.
In essence, a waterproofing membrane is applied to flat, smooth surfaces. This membrane is made out of extremely sticky and viscous organic liquids, with bitumen as the key ingredient. The surface must be sound, primed and completely clean before application.
The membrane is then applied by being “torched on” or heat-fused to the underlying surface. This creates a powerful watertight seal.
This technique is often used on flat roofs to prevent water leaks, but it can be used for a variety of applications in both residential and commercial buildings, such as roof slabs, planter boxes, balconies and patios and foundation or retaining walls.
Torch on waterproofing is a flexible membrane containing bitumen and a variety of polymers.
It can contain asphalt in one of two forms:
The bituminous membrane does not absorb any water at all, making it a resilient barrier to water and damp.
The membrane is reinforced with polyester or fiberglass and is available in several thicknesses. The material itself lasts for a long time.
All structures experience some level of movement and the membrane is flexible enough to adjust to this.
A number of mineral finishes allow you to adapt the appearance of the waterproofing to your structure’s style.
To top it off, it’s non-harmful to the environment. Bitumen is a non-toxic, organic hydrocarbon (created from crude oil) and it does not generate greenhouse gasses.
Remseal have been using the environmentally friendly torch method of waterproofing for the past 35 years. To enjoy the full potential of this technique, it is crucial to have the right team who will use the best materials and prep surfaces correctly for seamless adhesion.
