Dr. Fixit Torchshield AM 3160-4160 — APP Modified Bituminous Waterproofing Membrane Roll

Dr. Fixit Torchshield AM 3160-4160 is an APP (Atactic Polypropylene) modified bituminous waterproofing membrane from Dr. Fixit Waterproofing Solutions — available in 3mm (AM 3160) and 4mm (AM 4160) thickness variants, torch-applied directly onto primed concrete and masonry surfaces for seamless, long-lasting bitumen waterproofing protection.

Used in combination with Dr. Fixit Torchshield Primer as a complete system, the membrane is thermally fused to the substrate using a torch — creating a continuous, fully bonded bituminous waterproofing barrier with no joints, no seams, and no adhesive dependency. The APP modification ensures far better flexibility, thermal stability, and weather resistance compared to standard bitumen sheets — critical for roof waterproofing and terrace waterproofing surfaces that expand and contract with Indian temperature cycles and monsoon stress.

The 3mm variant (AM 3160) suits standard residential and commercial roof waterproofing and terrace waterproofing applications, while the 4mm variant (AM 4160) delivers additional thickness and protection for more demanding conditions — basement waterproofing, podium slabs, water retaining structures, and areas with higher hydrostatic pressure or heavier traffic exposure.

A proven, straightforward waterproofing solution trusted by waterproofing contractors across India — backed by Dr. Fixit's established construction chemical expertise and the reliable performance that comes with a properly applied torch-on APP waterproofing system.
