Basement Waterproofing in Mumbai
Water seeping through the walls or floor after rain, white salt deposits, or a musty smell? We stop active leaks, seal the joints and treat the concrete from the inside, so the space stays dry under water pressure.
- Suitable for
- Basements, podium parking, lift pits and plant rooms
- Inspection
- Free site visit
- Where
- Mumbai, Thane and Navi Mumbai
Signs you need it
- Water seeping through walls or the floor after rain
- Damp patches and peeling paint low on the walls
- White, powdery salt deposits (efflorescence)
- Water at the joint between the wall and the floor
- A musty smell, mould or condensation
- Rust stains or crumbling concrete
Why it happens
- 1.Groundwater pressure
- When the soil around a basement is saturated, water is pushed through any weakness in the concrete.
- 2.No outside waterproofing
- Many basements were built without an external membrane, or it has failed and can't be reached.
- 3.Construction joints and tie holes
- Joints between concrete pours, form-tie holes and honeycombed concrete give water an easy path in.
- 4.Cracks and pipe entries
- Shrinkage cracks and unsealed service entries let water through under pressure.
How we fix it
In an existing building the outside of the basement usually can't be reached, so we treat it from the inside with systems designed to resist water pushing from behind (negative-side waterproofing).
Injection grouting
Polyurethane or resin injected through packers into leaking cracks and joints, filling the path the water was using.
Best forActive leaks through cracks and construction joints
Crystalline waterproofing
A cementitious treatment whose chemicals react with moisture to grow crystals inside the concrete's pores and hairline cracks.
Best forDamp concrete walls and floors under water pressure
Negative-side cementitious coating
A polymer-modified cement coating rated for water pressure from behind, applied after repairs.
Best forMasonry and concrete walls that need a robust inner barrier
Drainage and sump
Internal drainage channels leading to a sump pump, for basements under constant high water pressure.
Best forVery wet sites where pressure can't be fully held back
What you get
- Dry, usable spaceStorage, parking, a gym or a plant room you can actually use.
- A protected structureKeeping water out of the concrete slows corrosion of the reinforcement.
- Healthier airLess damp means less mould and musty smell drifting through the building.
- Safer equipmentPumps, panels and stored goods stay out of standing water.
Our process
What happens, in order, from the inspection to the handover.
- 1
Leak mapping
We locate active leaks, damp areas, joints and pipe entries, and take readings.
- 2
Stop active water
Injection packers and fast-setting plugs stop running water first.
- 3
Surface preparation
Paint and weak plaster removed back to sound concrete.
- 4
Treatment
Crystalline or cementitious system applied, with joints and pipe entries detailed.
- 5
Finish and protect
Coving at the wall-floor joint and a protective finish where needed.
- 6
Monitor and hand over
We check the treated areas after heavy rain where possible, then hand over.
Suitable for
- Basements in residential towers
- Basement and podium car parks
- Lift pits
- Plant and pump rooms
- Retaining walls
- Underground stores and archives
What affects the cost
We don't publish one-size prices because the cause decides the treatment. These are the things that move the price.
- How much water is coming in, and under what pressure
- Area of walls and floor to treat
- Number and length of cracks and joints to inject
- Finishes to remove and restore
- Whether drainage or a sump is needed

Request a QuoteBasement FAQs
Can a basement be waterproofed from the inside?
Yes. Negative-side systems such as crystalline treatments, pressure-rated coatings and injection grouting are designed to work with water pushing from behind. They're the standard approach for existing buildings.
Will my basement be completely dry?
In most cases, yes. On very wet sites we may combine treatment with drainage and a sump. We'll tell you what's realistic for your basement before you commit.
Water is coming in right now. Can you still treat it?
Yes. Injection grouting works on actively leaking cracks, and fast-setting plugs stop running water so the rest of the treatment can go ahead.
Do you treat lift pits?
Yes. Lift pits are a common source of standing water. We stop the inflow and treat the pit so the equipment stays dry.
