10-Year Leak-Proof Warranty

Waterproofing Solutions in Chennai & Tamil Nadu

Eliminate water seepage and dampness permanently. Advanced elastomeric polymer membranes, PU injection grouting, cool-roof heat barriers, and underground tank food-grade liners.

Permanent Moisture Defense for Concrete Superstructures

In Tamil Nadu's intense subtropical climate—marked by scorching summer heat followed by heavy Northeast monsoon downpours—concrete slabs undergo significant thermal expansion and contraction. Without adequate waterproofing membranes, micro-fissures develop, allowing water to reach embedded TMT rebar. This causes rebar rust expansion, severe spalling, and toxic indoor mold growth.

At Sri Skandan Construction, under the engineering leadership of Er. R. Karthick Kumar, we reject temporary quick-fix patches. We engineer systematic multi-layer elastomeric polymer systems, crystalline capillary barriers, and polyurethane (PU) injection grouting that provide verified 10-year leak-proof structural protection.

High Elongation Polymer

300%+ elongation elastomeric membranes that bridge thermal expansion joints without tearing under severe solar heat.

Cool Roof Heat Barrier

High Solar Reflective Index (SRI > 105) top coat reducing roof surface temperature by up to 12°C and lowering AC power bills.

Targeted Waterproofing Treatment Zones

1. Terrace & Parapet Coving

Full surface grinding, polymer modified mortar coving at 90° corners, fiber mesh, and elastomeric UV coating.

2. Sunken Slabs & Bathrooms

Multi-coat 2K polymer cementitious barrier applied prior to plumbing pipe layout and light clinker backfill.

3. Potable Water Tanks & Sumps

Non-toxic, food-grade epoxy crystalline liners certified for potable drinking water storage sumps and overhead tanks.

4. Basement Retaining Walls & Lift Pits

Negative-side crystallization and polyurethane injection grouting to stop active water ingress through RCC joints.

5. Expansion & Construction Joints

Closed-cell polyethylene backer rods with high-movement polyurethane (PU) joint sealants.

6. External Walls Anti-Efflorescence

Silane-siloxane hydrophobic penetration coating preventing salt efflorescence leaching and hairline rainwater infiltration.

4-Stage Leak-Proof Execution Protocol

1
Mechanical Surface Preparation: High-pressure water jetting and mechanical grinding to remove loose laitance and algae.
2
V-Groove Crack Chasing & Sealing: Opening cracks with angle grinders, filling with non-shrink polymer grout, and rounding slab-wall corners.
3
Cross-Directional Multi-Layer Coating: Applying base coat, embedding glass-fiber reinforcing mesh, and applying dual elastomeric coats.
4
72-Hour Hydrostatic Water Ponding Test: Flooding the terrace with 50mm standing water for 3 full days to certify zero seepage before warranty issuance.

Waterproofing FAQs

Do I need to break the existing terrace tiles to waterproof my roof?

Not always. If the underlying screed is structurally sound and not hollow, we can clean the grout lines, seal joints with polyurethane sealants, and apply transparent or pigmented high-tensile PU hybrid membranes directly over existing tiles. If the screed has hollow debonding, we safely remove the loose tiles to apply the membrane onto the virgin slab.

How does the Cool Roof reflective coating reduce indoor temperatures?

Our cool roof coating features ceramic microspheres with a Solar Reflectance Index (SRI) above 105. It reflects more than 85% of solar infrared radiation, preventing heat from penetrating the concrete ceiling slab. This reduces interior ceiling temperatures by 4°C to 6°C and reduces air conditioning electricity costs by up to 25%.

Does Sri Skandan Construction provide a written waterproofing warranty?

Yes. Upon successful completion of our 72-hour hydrostatic ponding test, we issue an official 5 to 10-year written leak-proof performance warranty covering both material efficacy and application workmanship.
