Why Waterproofing Matters in Malaysia
Malaysia's heavy rain and high humidity make waterproofing essential. Without it:
- Water damages concrete and masonry over time.
- Mould and mildew thrive in damp areas, affecting health.
- Structural cracks widen as moisture weakens the material.
- Repair costs grow the longer a leak is ignored.
What to Expect from a Waterproofing Job
- Diagnosis — we identify where and how water is entering.
- Fixed quote — you receive a clear price for the recommended work.
- Preparation — the surface is cleaned and prepared.
- Application — the appropriate waterproofing system is applied (grout, membrane, or coating).
- Testing — the repair is checked, and the area is left clean.
Frequently Asked Questions
How much does waterproofing cost in KL & Selangor?
PU injection grouting starts from RM 300 per point, bathroom & wet area waterproofing from RM 1,000, and wall dampness repair from RM 350. Final pricing depends on the area and method.
What is PU injection grouting?
It is a method of stopping active water leaks in concrete by injecting polyurethane resin into the crack or joint under pressure. The resin expands and seals the leak from inside.
Can you waterproof an existing bathroom without breaking tiles?
In many cases, leaks can be stopped with injection grouting or surface waterproofing without removing tiles. The best method depends on where the water is coming from.
Do you also fix the source of the leak?
Yes. Waterproofing and leak repair go together — we find where the water enters and apply the correct system to stop it.
