How we deliver Waterproofing & Leak Repair Services — step by step
Every step is explained, every action is confirmed, and every handover is signed off. No hidden steps, no surprises.
- 01
Thermal Mapping
We track the water dampness spread to its highest moisture concentration point using thermal imaging meters.
- 02
Surface Prep / Drilling
For PU injection, we drill small 10mm holes at 45-degree angles intersecting the concrete crack. For membranes, we sand to raw concrete.
- 03
PU Injection / Primer
Expanding polyurethane chemical foam is pumped in at high pressure, filling all hairline capillary channels, or we apply a heavy bonding primer.
- 04
Membrane / Grout Seal
We apply three coats of fiber-reinforced waterproofing membrane, or remove the injection packers and seal the drill points with waterproof grout.
- 05
Water Ponding Test
We conduct a 24-to-48-hour standing water ponding test to ensure the seal is 100% impenetrable before finishing.

Waterproofing & Leak Repair Services FAQs — price, warranty and timing
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.
Related issues we can solve
Diagnose and solve common home issues before booking. Our problem guides help you understand what is happening and what to expect for repairs.
Damp Walls and Paint Bubbling
Paint bubbles, brown stains, or white salt marks appear because water is moving through the wall or slab.
Ceiling Leak After Rain
Ceiling drips or stains only during or after rain, often below roof, balcony, or exterior wall areas.
Upper-Floor Bathroom Leak
A lower ceiling drips below an upstairs bathroom, especially after showering or floor washing.
Roof Leak During Rainy Season
Water enters during storms through roof tiles, gutters, flashing, or flat roof membranes.
