When a torch-on membrane is the right choice
Torch-on works best on flat or low-slope concrete surfaces that need a durable, thick waterproofing layer. It is often recommended when an old coating has failed, or when a previous membrane has blistered or opened at the laps.
- Car porch roofs leaking at the slab or at the house wall joint
- Shophouse and terrace extension roofs with regular ponding
- Roof slabs under water tanks or mechanical equipment
- Old membranes with open laps, blisters or tears
- Roofs where a coating has cracked and keeps peeling
How torch-on membrane is installed
The membrane itself is only part of the job. Most early failures we see come from poor preparation or rushed laps, so our site team works in a set order.
- Surface check: confirm the roof falls to its drains and mark ponding areas
- Preparation: remove loose old layers, clean and dry the slab, repair cracks and broken edges
- Primer: apply bitumen primer so the membrane bonds to the concrete
- Torching: roll out the sheets, heat-weld them down and fuse every overlap
- Detailing: turn the membrane up walls and parapets, and reinforce drains, corners and pipe penetrations
- Final check and water test, then handover with the 10-year warranty

How much is torch-on membrane waterproofing in Malaysia?
Torch-on membrane waterproofing in Malaysia is indicatively RM7 to RM9 per sq ft in 2026, with a 10-year warranty. A 300 sq ft car porch would therefore cost roughly RM2,100 to RM2,700. The exact price is confirmed after our free inspection, depending on preparation, removal of old layers, upstands and access.
What is torch-on membrane?
Torch-on membrane is a reinforced bitumen waterproofing sheet. It is laid on a primed concrete surface and heated with a gas torch so it bonds to the slab, and each overlap is fused to the next sheet. The result is a thick, continuous waterproof layer, commonly used on flat roofs and car porches in Malaysia.
How long does torch-on membrane last?
Our torch-on membrane works carry a 10-year warranty. Real-world life depends on surface preparation, drainage and use. Roofs with blocked drains, constant ponding or frequent foot traffic wear faster, while a well-drained porch with clear outlets performs best. A simple post-monsoon check helps keep it in good shape.
