4mm Heavy-Duty Torch-On Smooth Waterproof Sheet
Our standard bituminous torch-on membrane features a smooth, uniform surface reinforced with a high-strength polyester core. This multi-layered design provides exceptional puncture resistance and structural toughness across expansive flat areas, keeping water from seeping into building concrete.
Surface Finish: Smooth/Normal (requires a protective screed layer or topping if exposed to foot traffic).
Best For: Foundation slabs, basements, balconies under screeds, and multi-layer roofing systems.
Key Benefit: Massive tensile strength and absolute puncture resistance across large surface areas.
Roll Dimensions: 4mm thickness × 10m² coverage per roll.
