Torch-on Membrane is a robust and highly durable method of waterproofing that utilizes factory-made bituminous (asphalt-based) sheets. The membrane is installed using a propane torch to partially melt the underside, fusing it directly and seamlessly to the concrete substrate. This technique creates an uninterrupted, single-layer, thick barrier capable of handling structural movement and hydrostatic pressure.
Key Problems We Solve:
- Structural Movement: The inherent flexibility of the bituminous sheet allows it to accommodate minor movements and thermal expansion/contraction of the building without cracking.
- Large Area Coverage: Ideal for vast flat surfaces like commercial roofs, large terraces, and below-grade foundation slabs where uniform thickness is critical.
- Hydrostatic Pressure: Used in specialized applications (like foundation waterproofing) to resist the constant external pressure exerted by saturated soil.
- Ponding Water Resistance: Provides an exceptionally robust and thick layer that stands up well to areas where water may occasionally collect (ponding).

Our Specialized Torching Techniques:
- Controlled Fusion: Application is carried out by trained experts who ensure the perfect temperature for fusion, guaranteeing 100% adherence to the substrate without damaging the membrane.
- Perfect Overlaps: All sheet joints are meticulously overlapped and double-torched to create a truly seamless and monolithic finish across the entire surface.
- Detailing & Flashing: Special attention is given to critical transition areas, such as parapet walls, drains, and pipe penetrations, using reinforced sheets and precise flashing techniques to prevent common leak points.
- Surface Protection: The final layer is typically covered with protective screed, tiles, or ballast to shield the membrane from UV damage and wear.
Result: We provide a heavy-duty, long-lasting, and thick waterproof system that offers decades of protection against water ingress, making it one of the most reliable solutions available.
