Torch On Membrane Waterproofing

services-big

Torch-on membrane waterproofing is a popular and effective method for waterproofing flat or low-slope roofs and other surfaces. This technique involves the application of a specialized waterproofing membrane that is made from modified bitumen, also known as modified asphalt. The term "torch-on" comes from the process of heating the membrane's underside with an open flame torch to adhere it to the substrate.

Torch-on membranes are typically made from a combination of bitumen and various polymers, such as SBS (Styrene-Butadiene-Styrene) or APP (Atactic Polypropylene). These additives enhance the membrane's flexibility, durability, and resistance to temperature fluctuations.

Steps for Torch-on membrane waterproofing:

  • Safety Precautions: Before starting any work, ensure all safety precautions are in place. This includes wearing appropriate personal protective equipment (PPE), such as fire-resistant clothing, safety goggles, and gloves.
  • Surface Preparation: Clean the substrate (roof deck) thoroughly to remove dirt, dust, debris, and any loose materials. Ensure the surface is dry and smooth.
  • Installation of Base Sheet: Roll out and mechanically fasten or adhere a base sheet to the prepared substrate. The base sheet provides additional reinforcement and stability to the roofing system.
  • Layout and Planning: Plan the layout of the torch-on membrane rolls, considering the most efficient and effective way to cover the entire area.
  • Installation of Torch-On Membrane: Use a propane torch to heat the bottom surface of the membrane as it is being unrolled. The heat melts the bitumen and creates a strong bond between the membrane and the substrate.

Proper expansion joint treatment is essential for ensuring the longevity, safety, and functionality of buildings and structures. Regular maintenance and adherence to manufacturer recommendations and building codes are critical for preserving the effectiveness of expansion joint systems.

Application:

Surface Preparation: The substrate (typically the roof deck) must be cleaned and prepared to ensure good adhesion.

Installation of Base Sheet: A base sheet, often reinforced with fiberglass or polyester, is applied using mechanical fasteners or adhesive..

Torch-On Membrane: The torch-on membrane is rolled out over the base sheet, and the bottom surface is heated using a propane torch to melt the bitumen. This creates a strong bond with the base sheet and the substrate.
