Ground water pushes into lift pits from outside — ordinary coatings peel right off. Our crystalline and injection-grouting systems work from the inside (negative side) and need no excavation.
Negative-side treatment — no digging around the building.
PU injection grouting seals running water on the spot.
Crystals grow into capillaries and re-seal hairline cracks.
Quick treatment with the lift back in service fast.
| System | Crystalline coatings / PU & epoxy injection grouting for active leaks |
|---|---|
| Application | Works from inside (negative side) — no excavation needed |
| Surface Prep | Pressure grouting of honeycombs, kicker joints sealed |
| Best For | Lift pits, basements, underground tanks |
Housing societies and builders with water standing in lift pits or seeping basement walls.
The pit is dewatered, active leaks are sealed with PU injection grouting, and crystalline coatings are then applied to handle ground-water pressure from the negative side — all without external excavation.
Crystalline compounds react with concrete and moisture to grow needle-like crystals inside the pores, blocking water paths permanently and even self-healing hairline cracks that appear later.
Most lift pits are treated in 3–5 days including dewatering, injection and coatings, after which the lift can return to service.
