Torch-On Membrane Waterproofing Solution
Torch-on membrane provides durable, long-lasting waterproofing for flat roofs, exposed decks, and other surfaces. Made from high-quality modified bitumen reinforced with a polyester core, it offers flexibility, UV resistance, and protection against cracks, leaks, and surface wear.
This seamless waterproof layer enhances structural durability, withstands harsh weather, and reduces maintenance, delivering reliable protection for years to come.
What is Torch-On Membrane
A torch-on membrane (also known as a torch-applied membrane) is a durable and time-tested waterproofing system that belongs to the bituminous membrane family. It is applied using controlled heat from a propane gas torch, which melts the underside of the membrane and allows it to bond securely to the surface, hence the name “torch-on.”
Our torch-on membranes are made from high-quality modified bitumen, reinforced with a strong polyester core for extra strength and flexibility. This advanced material formulation makes the membrane highly resistant to UV rays, heat, and environmental stress, ensuring long-term stability even under harsh weather conditions. Ideal for flat roofs, exposed decks, and warm climates, the system forms a seamless waterproof layer that protects against water ingress, cracking, and surface wear.
By combining proven bituminous technology with expert installation, we deliver a reliable, weatherproof solution that extends the lifespan of your structure and reduces maintenance needs over time.
Key Benefits of Torch-On Membrane
Our torch-on membrane offer superior durability, UV resistance, and mechanical strength, ensuring a watertight barrier that stands up to heat, heavy use, and years of weather exposure. Ideal for commercial and residential projects that demand proven, low-maintenance protection.
Durable
Forms a thick, multi-layer sheet that resists wear. Lifespan of 20–30 years with our experience installation.
Resistant
Flexible and elastic, able to withstands mechanical stress, UV, and temperature extremes.
Repairable
Damaged areas can be easily to patch by re-torching locally, no need to re-coat entire area.
Torch-On Membrane Application Method
Let’s take a layer-by-layer deep dive into the method of applying a torch-on membrane waterproofing system, breaking down each stage from the substrate to the final protective layer, with clear steps, technical details, and practical considerations.
-
First Layer: Surface Preparation
To clean and ready the substrate so it is smooth, dry, and free of contaminants, ensuring proper adhesion of all following layers. -
Second Layer: Apply Bitumen Primer
To seal the substrate and create a tacky, uniform base that improves adhesion between the surface and the torch-on membrane. The primer also helps reduce moisture diffusion from the substrate, ensuring optimal performance of the torch-on membrane. -
Third Layer: Installation of Torch-On Membrane
To provide the main waterproofing barrier, forming a durable, seamless layer that prevents water penetration.
