RCC / CONCRETE ROOF WATERPROOFING IN KARACHI
Professional Concrete Slab Waterproofing, Crack Repair & RCC Roof Treatment*
KCS Waterproofing Karachi provides specialized RCC roof waterproofing and concrete slab leakage repair services for houses, buildings, factories, and commercial properties across Karachi and Sindh. Concrete (RCC) roofs naturally develop:
Hairline cracks
Slab seepage
Surface deterioration
Joint separation
Drainage leakage
Water absorption
Structural weakening
Because RCC is porous, it absorbs moisture easily — especially during monsoon season.
Our RCC waterproofing solution ensures 100% leakproof protection, enhanced durability, and long-term resistance against water seepage.
We use advanced materials such as:
Sealant XT100 (modified polymer crack sealant)
Aquashield AS100 (liquid rubber waterproofing membrane)
UV Reflector 101 (heat & UV protection coating)
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.
