Torch-on bitumen membranes, applied using blow torc​h to heat and bond the material to the substrate, are available in two main surface finishes—Granule and Sanded—each designed for specific applications and performance needs.

The sanded torched-on membrane is a flexible bituminous waterproofing layer designed for covered applications such as under screeds, tiles, or concrete toppings. Its fine sanded surface enhances adhesion and provides a solid base for mortar or adhesives, making it ideal for flat roofs and wet areas not exposed to UV radiation.
