Five-year-warranty waterproofing — sized for the Malaysian monsoon.
A short patch keeps you dry until December. Tracenex installs polyurethane, polymer and torch-on systems that survive a full storm season and pass independent test reports.
Which system fits your roof?
We do not have a “house brand”. We pick the right system for the substrate, slope and exposure. Common selections in Klang Valley:
- Polyurethane membrane (PU) — the workhorse system. UV-stable, foot-trafficable and bridges hairline cracks in concrete decks.
- Acrylic polymer coating — budget-friendly for tin and metal-deck warehouse roofs that are not foot-trafficked.
- Torch-on bitumen sheet — for older flat concrete roofs with serious thermal movement.
- Crystalline / cementitious system — for water-positive faces such as basement tanks and gutters.
- Hybrid PU + polyurea — for fast-track commercial jobs that need to be in service within 24 hours.
How a Tracenex roof job runs
- Site walk-through with infra-red moisture mapping and photographs of every defect.
- Written quote with the chosen membrane, surface preparation and warranty terms.
- Surface prep — grinding, cleaning, primer and crack repair using polymer-modified mortar.
- Two-coat membrane with reinforcement fleece at parapets, drains and skylight upstands.
- Wet film test and a 48-hour ponding test before sign-off.
- Handover with photo report and warranty certificate.
Practical considerations for Malaysian homes
Tropical rainfall and UV pose two competing stressors: water needs to drain off, and the membrane needs to flex under sun-cycle heat without cracking. Most failure cases we see come from contractors specifying a single-coat polymer over uncleaned concrete — it looks great for six months and then peels off. Our standard PU spec adds a primer coat, two-coat membrane and a reinforcement fleece at every upstand.
