Karachi Roof Waterproofing & Heat-Proofing | Protect Your Home From Rain & Heat
7-Layer Advanced RCC Waterproofing Process
-
Layer 1: Surface Deep-Cleaning & Primer Prep – High-pressure cleaning and penetration priming to lock the concrete base without civil breaking.
-
Layer 2: Crack Repair & Joint Sealing (Sealant XT100) – Structural crack treatment using Sealant XT100 modified polymer waterproofing sealant to seal active leaks and expansion joints.
-
Layer 3: Primary Chemical Waterproofing Coat – Initial liquid-applied elastomeric barrier to establish an impenetrable base shield against water absorption.
-
Layer 4: Full Fabric Matrix Reinforcement – Full roof surface reinforcement with non-woven fabric pasting to add high tensile strength and bridge structural movement.
-
Layer 5: Intermediate Binding Coat – Penetrating chemical layer engineered to weld the fabric membrane matrix securely to the base coats.
-
Layer 6: Secondary Leak-Proof Barrier – Heavy-duty intermediate chemical coating ensuring 100% pinhole-free coverage across the entire slab.
-
Layer 7: Protective Topcoat (Aquashield AS100) – Final weather-resistant shield using Aquashield AS100 Polyurethane Rubber Coating for extreme elasticity, UV resistance, and standing-water protection.
By combining deep chemical waterproofing barriers with reinforced fabric membrane technology, this zero-demolition system forms a seamless, highly elastic, and durable waterproof shield over your entire concrete roof area—backed by a 5 to 10-year written warranty.

WHY RCC ROOFS LEAK?
Concrete roofs leak due to natural porosity and weather impact.
Common causes include:
✔ Hairline cracks from heat expansion
✔ Poor slope / water standing
✔ Weak slab waterproofing during construction
✔ Open joints & surface gaps
✔ Broken drainage points
✔ UV exposure damaging the surface
✔ Aging concrete losing strength
✔ Heavy rainfall penetration
Our chemical-based waterproofing system solves all these issues without breaking tiles or damaging the slab.
OUR RCC / CONCRETE WATERPROOFING SERVICES
✔ RCC Roof Waterproofing Coating
We apply a thick, flexible waterproofing membrane (AS100) that seals the slab and prevents water from entering concrete pores.
✔ Crack & Joint Repair (Sealant XT100)
All visible and invisible cracks are injected and sealed with XT100 for permanent flexibility.
✔ Concrete Surface Preparation
We clean the slab, remove loose material, treat fungus, and prepare a strong bonding base.
✔ Two-Layer Waterproofing System
A primer + two heavy coats of Aquashield AS100 are applied for reinforced protection.
✔ UV Protection Layer (UV Reflector 101)
Optional topcoat to reflect heat, protect from UV rays, and extend membrane lifespan.
✔ RCC Slab Restoration
We repair surface damage, fill cavities, and improve structural durability.
✔ Drainage & Slope Leak Fixing
We seal drain joints, pipeline connections, and water outlets — the most common leak points.
OUR RCC ROOF WATERPROOFING PROCESS
1. Inspection & Moisture Analysis
Identify cracks, weak points, water pockets, and slab damage.
2. Crack Probing & Sealing (XT100)
Cracks are opened slightly (if required), cleaned, and sealed with XT100.
3. Priming the Concrete Surface
A bonding primer is applied to ensure strong adhesion.
4. Waterproof Membrane Application (AS100)
Two heavy coats of liquid rubber membrane create a seamless, elastic waterproof layer.
5. UV Reflective Finish (UV101)
Optional final layer reduces heat and increases coating lifespan.
6. Final Inspection & Quality Testing
We check for any unsealed points, ensuring complete water resistance.
