Penetrative waterproofing · A decade of experience

We stop leakage without breaking your building.

We don't believe in breaking and hammering. Our penetrative treatment soaks into your concrete and makes the structure itself repel water — so your building stays intact and in use while we work. Backed by a warranty on notarized stamp paper.

Why penetrative, not surface coating

The waterproofing goes inside the concrete, not on top of it.

Ordinary coatings and brickbat coba sit on top of your slab — they crack, peel and get redone every few years. Our chemistry soaks into the pores of the structure and converts it from water-absorbing to water-repelling, so the protection is part of the concrete rather than a layer over it. No breaking or hammering required to get it there.

We apply until full saturation — the point where the surface stops absorbing altogether. That's how the treatment reaches its full depth instead of sitting on the surface, and it's the difference between waterproofing that lasts and a quick coat that doesn't.

BENEFIT / 01

Water can't get in

The treated structure turns hydrophobic — water beads and rolls off instead of soaking into the slab and walls.

BENEFIT / 02

Non-invasive by principle

We don't believe in breaking and hammering. Your terrace, tiles and plaster stay intact — and residents keep using the space while we work.

BENEFIT / 03

Cooler slab, lower AC bills

Treated slabs run up to 10° cooler, easing the load on air conditioning in top-floor flats.

BENEFIT / 04

No algae, no black patches

Algae grows where water sits. A dry, breathable surface stays clean — and paint lasts visibly longer.

BENEFIT / 05

Breathable protection

Trapped moisture escapes as vapour, so the treatment doesn't bubble or peel like film-forming coatings.

BENEFIT / 06

Done in days, not weeks

Applied by a trained crew with no demolition stage to work through — most society terraces finish in a fraction of the time brickbat coba takes.

What we waterproof

One dedicated solution for every leakage point.

Terrace waterproofing

Stop monsoon leakage into top-floor flats — without breaking the terrace or removing tiles.

Bathroom & toilet leakage

Sunken slab seepage staining the ceiling of the flat below — treated without demolishing the bathroom.

Read the full process →

Podium slab waterproofing

Gardens, driveways and play areas above basements and parking — sealed against ingress from above.

Read the full process →

Dead wall & side wall seepage

Damp patches and peeling paint from walls you can't easily access — treated from the outside in.

Read the full process →

Parapet wall waterproofing

The most exposed wall of your building — often the hidden source of "terrace" leakage.

Read the full process →

Overhead tank waterproofing

Hydrostatic-pressure leakage from rooftop tanks — sealed for structural safety and clean water.

Who we work with

If it absorbs water, we can treat it.

Concrete, brick, plaster and stone all drink water — which is why leakage looks the same whether it's a 40-flat society or a single shop. Tell us what's leaking and we'll inspect it.

Housing societies

AGM-ready quotations, work scheduled around residents, references from other societies, and a notarized warranty your committee can file. Typical projects: full terrace, parapet and tank treatment for buildings from 1,000 sq ft upwards. See how we work with committees →

Builders & developers

Large-plot capability, defined timelines, and documentation that stands up in handover. Waterproofing done right before possession costs a fraction of post-occupancy repairs.

Villa & bungalow owners

Second home in Lonavala or Goa leaking while you're in Mumbai? Send us photos and videos on WhatsApp — we assess remotely, then schedule the site visit.

Homes, shops & everything else

A single flat, a shop, a farmhouse, a factory shed, a temple, a warehouse — if water is getting in, tell us. We'll inspect it and tell you honestly whether it's a job for us. Send us the details →

The Keshav promise

Our warranty isn't a verbal assurance. It's on notarized stamp paper.

Every project comes with a 5, 7 or 10-year warranty — legally documented, notarized, and handed to you with the completion report. If the treated area leaks within the warranty period, we return and fix it. In writing, not on trust.

Proof of work

Recent projects across Maharashtra, Goa & Gujarat.

Our work so far, measured honestly:

50+

Projects completed — villas, housing societies and commercial & industrial facilities across Maharashtra, Goa & Gujarat.

10 lakh+

Square feet waterproofed — terraces, podiums, walls and tanks, treated without breaking a single structure.

A decade

Of waterproofing experience, CIDC certified — with projects underway right now across Maharashtra, Gujarat and Goa. Pre-monsoon slots fill first.

Detailed case studies with photos are on their way. Until then, ask us on call for project references relevant to your building type — we'll connect you with committees we've worked with.

Common questions

Answers before you even call.

Can leakage really be fixed without breaking tiles or the terrace?
Yes. Our penetrative treatment is applied to the existing surface and soaks into the concrete, making the structure itself water-repellent. There is no hammering, no removal of tiles, and no debris — which is why societies prefer it over brickbat coba redo.
How long does the waterproofing last?
The treatment chemically bonds with your structure rather than sitting on top of it, so it doesn't peel or crack like surface coatings. We stand behind it with a notarized warranty of 5, 7 or 10 years depending on the service and site condition.
Can waterproofing be done during the monsoon?
Outdoor surfaces like terraces need a dry window of 3–4 days, so most terrace work is scheduled between monsoon spells or after the season. Internal work (bathrooms, tanks) can proceed year-round. If you're leaking right now, call us — we'll inspect, plan, and lock your slot for the first dry window.
Do you work on individual flats or only full buildings?
Our core work is full buildings, societies, developer projects and independent villas/bungalows. For a single flat's issue, the leakage source usually lies in a common area (terrace, parapet, dead wall) — we help committees address it at the source.
What does the notarized warranty actually cover?
It's a legally documented commitment on stamp paper: if the treated area leaks within the warranty period, we return and rectify it at no cost. The document states the treated areas, warranty duration, and claim process. See the warranty page for a sample.

Leakage doesn't wait for your AGM. Book the inspection now.
