How Basement Waterproofing Works
Basement waterproofing addresses the root cause of moisture ingress: hydrostatic pressure from saturated soil pushing water through porous concrete and masonry. In Kanpur, where the water table rises sharply during the June–September monsoon, below-grade structures are under constant hydraulic stress.
Crystalline penetrative treatment is the most durable approach. Active chemicals are brushed onto dampened concrete and migrate deep into the matrix, reacting with calcium hydroxide to form insoluble crystite crystals. These crystals permanently block capillary pores and self-seal any future micro-cracks when moisture is present.
For walls under active hydrostatic pressure — where water is visibly seeping — we use negative-side cementitious slurry, applied from the interior without excavation. Structural cracks and construction joints are sealed with low-viscosity epoxy injection, restoring the full strength and impermeability of the original concrete.
Where drainage is a concern, we integrate sump pit and perimeter drainage channel systems to relieve hydrostatic pressure before it can build against the wall face.
Signs You Need Basement Waterproofing
- Damp or wet walls even in dry weather
- White salt deposits (efflorescence) on concrete surfaces
- Persistent musty or earthy smell inside the basement
- Standing water on the floor after monsoon rain
- Rust-coloured stains streaking down walls
- Visible mould or mildew colonies on walls or ceiling

Our 5-Step Approach
Every basement waterproofing project follows a strict, documented process — no shortcuts.
Detailed Inspection
Our waterproofing engineer visits your site to identify all active seepage points, map hydrostatic pressure zones, and document the full extent of moisture ingress — at zero cost.
Crack Mapping
Every crack, construction joint, honeycombed section, and pipe penetration is photographed and marked on a floor plan. This forms the basis of your written remediation report.
Surface Prep — Chip & Grind
Loose concrete, existing paint coatings, and contaminated layers are removed by chipping and grinding. Cracks are opened to a V-profile for proper product anchorage.
Crystalline Application
Dampstop Advanced or Crystalline Slurry CT-100 is brushed onto dampened concrete in two coats. The active chemicals penetrate pores and hairline cracks, forming insoluble crystals that self-seal over time.
Flood Test & Warranty
After 28-day curing, a ponding flood test is conducted to verify zero water ingress. A written warranty certificate is issued, covering materials and workmanship.
Specified Products
Products We Use
Premium-grade materials sourced from certified manufacturers — every product is site-tested before specification.
Dampstop Advanced
Penetrative crystalline waterproofing compound for below-grade masonry and RCC concrete. On contact with moisture, catalytic chemicals react to form insoluble crystite crystals that permanently block pores and micro-cracks.
- Coverage: 1 kg/m²
- Bond strength: 3.5 N/mm²
- Crystalline depth: 25 cm+
Crystalline Slurry CT-100
Negative-side cementitious slurry for active leak points and below-grade walls subject to high hydrostatic pressure. Bonds tenaciously even to wet or damp substrates with no delamination risk.
- Application rate: 1.5 kg/m²
- Design life: 25 years
- Works under negative pressure
Sump Seal Epoxy
Two-component rigid epoxy injection resin for structural crack sealing in basement floors and walls. Restores full structural integrity and provides an impermeable barrier against hydrostatic water pressure.
- Bond strength: 10 MPa
- Viscosity: 200 cP (low)
- Pot life: 20 min at 25°C

FAQ
Frequently Asked Questions
What causes basement seepage in Kanpur homes?
Kanpur's high water table — especially in areas like Rawatpur, Kidwai Nagar, and near the Ganga canal — creates constant hydrostatic pressure against basement walls. Combined with poorly compacted backfill, inadequate waterproofing during original construction, and hairline cracks in RCC, moisture finds a path inside. Monsoon seasons dramatically worsen the situation, saturating the surrounding soil.
How long does crystalline basement waterproofing last?
Crystalline treatment is a permanent solution because the crystals become part of the concrete matrix itself. Unlike surface membranes that can peel or crack, crystalline compounds penetrate 25 cm or more into the slab. Our CT-100 slurry carries a 25-year design life. With proper workmanship, many crystalline-treated structures remain watertight for the full life of the building.
Can you treat a basement that is currently occupied or in use?
Yes, in most cases. Negative-side crystalline and cementitious slurries are applied from the interior, so there is no need to excavate around the building or vacate the property for extended periods. Work is usually done in 2–4 days depending on the basement area. We schedule work in phases so that storage areas can remain partially accessible.
What is crystalline waterproofing and how is it different from a membrane?
A traditional membrane sits on the surface and forms a physical barrier. If it cracks or delaminate, water gets in. Crystalline waterproofing uses reactive chemicals that migrate deep into the concrete and permanently fill capillary pores and hairline cracks with insoluble crystals. Any future micro-crack that develops in the treated zone will self-seal when moisture activates dormant chemicals — making it a self-healing system.
