Torch on Membrane

Torch-on membrane waterproofing is a specialized method used to create a durable and effective waterproof barrier on various surfaces, such as roofs, decks, and basements. It involves the application of a waterproofing membrane composed of modified bitumen, a type of asphalt mixed with polymers or other additives to enhance its properties.

The process begins with the preparation of the surface, which typically involves cleaning and priming to ensure proper adhesion. Next, the torch-on membrane is rolled out onto the surface and carefully heated using a propane torch or other heat source. As the membrane is heated, it softens and adheres to the surface, forming a seamless and watertight seal.

The torch-on membrane consists of multiple layers, usually referred to as plies. These plies are applied one on top of the other, with each layer overlapping the previous one, to create a robust and continuous waterproofing system. The number of plies used depends on the specific requirements and desired level of waterproofing.

Once the membrane is applied, it forms a flexible and resilient barrier that is resistant to water, moisture, and various environmental elements. This method of waterproofing offers several advantages, such as excellent durability, UV resistance, and the ability to withstand thermal expansion and contraction without compromising its effectiveness.

Torch-on membrane waterproofing is commonly used in both residential and commercial construction projects. It is particularly well-suited for flat or low-slope roofs, where proper drainage is essential to prevent water pooling and potential leaks. Additionally, it can be applied to vertical surfaces, providing reliable waterproofing for below-grade areas or exterior walls.

It is important to note that torch-on membrane waterproofing requires skilled and experienced professionals to ensure proper installation and adherence to safety procedures. The use of open flames and heat sources during the application process necessitates caution and adherence to fire safety guidelines.
