Commercial Waterproofing

Professional Commercial Waterproofing in Pune & PCMC

Comprehensive waterproofing for offices, apartments, shops, malls, warehouses, and other commercial properties across Pune and PCMC.

Leakproofs by Betterwork has been carrying out this work across Pune and Pimpri-Chinchwad for more than 10 years. Every job starts with a free deep-scan inspection, because the point where water appears is very often not the point where it enters.

Common problems we find

Commercial buildings in Pune — the IT parks along Hinjewadi and Kharadi, the retail and office stock in Baner, Viman Nagar and Camp — leak in a pattern set by how they are built and how they are occupied, not by the weather alone.

• Podium decks and terrace gardens. A landscaped or trafficked podium is a buried roof with occupied space underneath. Once it leaks, the membrane is under soil, paving or a car park, and the cost of access dwarfs the cost of the repair. Root penetration and blocked drainage layers are the usual causes.
• Basement parking. Below the water table, the pressure is permanent rather than seasonal. Leaks appear at construction joints, at the wall-to-raft kicker, and around service entries that were sleeved but never sealed.
• Stacked toilet cores and AHU rooms. A single failed floor waterproofing in a wet area shows up as ceiling staining several floors down, because water travels along the slab soffit and down service shafts. Tenants report it as a roof leak; it almost never is.
• Glazing and curtain-wall junctions. The interface between the glazing system and the concrete structure is a different trade’s responsibility from the waterproofing, which is exactly why it is the junction most often left undetailed.
• Fit-out damage. Every tenant churn puts anchors through a floor screed, cores a wall for services, or lifts tiles in a wet area. Membranes are routinely breached during fit-out and not reinstated.
• Expansion joints. Long commercial floor plates need them, and a joint treated as a crack — filled with sealant and coated over — reopens within a season.

The business cost is not the repair. It is the ceiling tile in a client-facing area, the lift lobby cordoned off, and the service-charge dispute with tenants that follows.

How we treat it

Commercial work is planned around occupancy first and the specification second, because a technically perfect method that needs the lobby closed on a weekday is not a usable method.

Survey. We establish the actual water path before quoting. Thermal imaging maps wet zones in slabs and behind finishes; a moisture meter confirms them; where the source is ambiguous between plumbing and envelope, we isolate and dye-test rather than guess. On podiums we trace drainage outlets and check whether the drainage layer is still functioning under the build-up. The output is a leak map, not a rate card.

Preparation. Finishes lifted only where the map says they need to be. Substrates ground back to sound concrete, laitance removed, cracks cut and filled, and a coved fillet formed at every wall-to-floor junction. In basements, active water is stopped first with a plug mortar or injection before any coating goes on — coating over a live leak is the most common failed repair we are asked to redo.

Systems. Podium decks get a reinforced liquid-applied PU or a torch-applied membrane with a protection board and a functioning drainage layer reinstated above it — the drainage layer is not optional and its absence is why the first membrane failed. Basements are treated on the negative side with crystalline slurries where excavation is impossible, and on the positive side where it is not. Wet-area floors get a cementitious or PU tanking layer dressed up the walls above the finished floor level and taken into the drain body. Expansion joints get a purpose-made joint system, never sealant alone.

Sequencing. Night and weekend working, floor by floor or bay by bay, with the area handed back clean and trafficable each morning. We coordinate directly with facilities and with tenant fit-out contractors so that a reinstated membrane is not breached the following week.

Verification. Wet areas are flood-tested for 24 hours with the ceiling below under observation, podium decks are flood-tested before the build-up goes back, and dry film thickness is recorded per zone. Leakproofs by Betterwork issues the written warranty only after the test passes.
