Why basements leak
Basements, cellar parking and lift pits sit below ground level, so the soil around them holds water against the walls and floor, especially during and after the monsoon. That water finds construction joints, tie-rod holes, honeycombed concrete and cracks, and pushes through under pressure.
Because the outside face of an existing basement cannot be reached without excavation, our basement waterproofing in Hyderabad works from the inside (negative side). Active leaks are stopped with PU injection grouting, and the walls and floor are then treated with crystalline or cementitious systems that resist water pressure.
Signs your basement needs waterproofing
- Water seeping through wallsWet patches or trickles, often along horizontal construction joints.
- Water on the basement floorPuddles after rain, or water rising through the floor slab.
- Leaking lift pitStanding water in the lift pit, which can damage lift equipment.
- White deposits and rust stainsEfflorescence on the concrete and rust bleeding from tie-rod holes.
- Damp smell and fungusPersistent musty air in cellar parking or storage rooms.
- Cracks in retaining wallsCracks that stay wet or grow over time.
Our basement waterproofing process
Survey of leak points
We map every active leak, crack, joint and tie-rod hole across the walls, floor and lift pit.
Injection grouting
Holes are drilled along the cracks and joints, packers fitted, and PU grout injected under pressure to seal the path from inside.
Surface repair
Honeycombed concrete and damaged areas are cut back and repaired with non-shrink mortar.
Crystalline or cementitious coating
A coating that bonds with the concrete and resists water pressure from the soil side.
Monitoring after rain
We check the basement after the next heavy rain and treat any remaining weak spots.
Basement waterproofing systems
PU injection grouting
Expanding polyurethane grout that seals active, flowing leaks inside cracks and joints.
Crystalline waterproofing
Penetrates concrete and forms crystals in the pores, blocking water even under pressure.
Cementitious coatings
Rigid or flexible cement-based coatings for walls and floors on the negative side.
Epoxy injection
For structural cracks that need to be bonded as well as sealed.

Basement Waterproofing: frequently asked questions
Yes. For existing buildings, inside (negative-side) waterproofing with injection grouting and crystalline coatings is the practical option, because the outside of the wall is buried.
Yes. PU injection grouting works on wet and actively leaking concrete, so we can stop running water even during the rains. Coatings are applied once the leaks are controlled.
Yes. Lift pits are one of the most common leak points in apartment basements and are treated with injection grouting and a crystalline or cementitious system.
It depends on the number of leak points and the area. A single lift pit may take a day; a full parking basement can take one to two weeks.
