RCC / CONCRETE ROOF WATERPROOFING IN KARACHI
Professional Concrete Slab Waterproofing, Crack Repair & RCC Roof Treatment
KCS Waterproofing - Roofing Specialist concrete roof waterproofing services involve sealing porous reinforced concrete (RCC) structures against water damage using specialized coatings (Sealant XT100, Aaquashield AS100), membranes, or chemical treatments to stop leaks, prevent seepage, and enhance durability, Specially applied to roofs, basements, and water tanks using methods like XT100 modified
polymer, AS100 polyurethane rubber coating, cold applied bitumen, or UV heat-reflective 101 solutions to protect against rain and sunlight
KCS Waterproofing - Roof repair involves fixing from minor damages to major roof damages, properly seal issues like leaks, cracked or missing shingles, and damaged flashing, often using sealant xt100, patch materials, or replacing individual components to extend the roof's life, with specialized methods including applying roofing materials (Sealant XT100, Aquashield AS100), reinforcing with fabric, or non-fabric sheet,
though severe surface damage might require cement plaster repair before waterproofing. We are specialist in fixing from minor problems to complex repairs, especially on flat/RCC/concrete roofs residential/commercial/industrial in Karachi.
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, and 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.
