Practical guidance for KL & Selangor
Malaysian homes face tropical humidity, fast rain cycles, condo management rules, and mixed construction materials. That means the right method depends on surface condition, access, safety requirements, and whether water or structural movement is involved.
The safest approach is to shortlist the likely cause, collect clear photos, confirm the property type, and request an itemised fixed-price quotation. KL Servis Rumah confirms scope before work begins and avoids arbitrary pricing.

FAQs
What is PU Grouting (Injection), and how does it stop water leaks?
Polyurethane (PU) high-pressure injection is a non-destructive method where we drill small ports under the leaking concrete slab. We inject liquid PU foam which reacts with moisture and instantly expands up to 20 times its size, filling every microscopic crack and void. It cures into a flexible, tough, and permanent rubber seal that blocks water completely, without requiring you to tear up your bathroom floors.
How long does a waterproofing membrane last in Malaysian weather?
A professional, multi-layered liquid or torch-on membrane on concrete roof slabs or balconies, when applied with proper UV-resistant protective topcoats, will easily last 5 to 10 years. We provide up to a 5-year written guarantee on complete re-waterproofing works.
Is the dampness or peeling paint on my lower wall a waterproofing issue?
Yes. This is called 'rising damp' or water seepage. It occurs when groundwater or bathroom water seeps into porous wall bricks. We treat this by scraping off the peeling paint, treating the wall with salt-neutralizing chemicals, and applying a heavy-duty commercial epoxy or crystalline waterproofing barrier before repainting.
Do you perform water ponding tests after waterproofing?
Absolutely! For all bathroom, balcony, and flat roof slab waterproofing, we block the drains and flood the floor with 2 inches of water for 24 to 48 hours. We check the ceiling below to confirm there is absolutely zero moisture transfer before we lay tiles.
