Penetrative treatment for society and building terraces across Mumbai, Thane and Pune. The terrace stays usable during work, the slab runs up to 10° cooler after — and the warranty comes notarized on stamp paper.
Terrace slabs take the full force of Mumbai's monsoon — four months of standing water, then eight months of heat expanding and contracting the concrete. The usual culprits:
Left untreated, seepage corrodes the steel reinforcement inside the slab — turning a waterproofing problem into a structural repair bill many times larger.
That said, not every ceiling stain is a terrace problem. The same damp patch can come from the parapet, a dead wall or side wall, an overhead tank, or a bathroom above. This is exactly why we inspect and trace the source before quoting — so you pay to fix what is actually leaking, not what is easiest to sell.
| Method | Penetrative chemical treatment, applied to full saturation |
|---|---|
| Breaking / hammering | None — existing surface stays intact |
| Terrace usable during work | Mostly — brief restricted access during application & curing |
| Typical project size | Societies, buildings & independent homes — 1,000 sq ft and up |
| Duration | Days, not weeks (confirmed after inspection) |
| Slab temperature | Up to 10° cooler after treatment |
| Warranty | 5 / 7 / 10 years · notarized on stamp paper |
| Best season | Post-monsoon, or a 3–4 day dry window |
We trace where water is actually entering — often the parapet or joints, not the slab everyone suspects — before quoting anything.
Cleaning and opening the surface pores. No hammering, no chipping, no debris trucks in your compound.
Existing cracks and joints are treated so the flexible topcoat can bridge them permanently.
The chemistry is applied to full saturation — until the slab stops absorbing altogether — so it reaches full depth and converts the concrete itself from hydrophilic to hydrophobic.
A breathable, UV-resistant, crack-bridging layer seals the system — moisture inside escapes, water outside stays out.
We verify the result with water, then hand over your completion report with the notarized warranty document.
| Brickbat coba / membrane redo | Penetrative treatment (ours) | |
| Breaking required | Yes — old layer demolished, debris removed | None |
| Time on site | Weeks | Days |
| Weight added to slab | Significant dead load | Negligible |
| Failure mode | Layer cracks, traps water, leaks return | No separate layer to crack |
| Terrace usable during work | No — out of use for weeks | Mostly — brief restriction only |
