Advanced waterproofing solutions for terraces, basements, water tanks, and wet areas — matched to how water actually reaches your structure.
Water is the biggest threat to a building’s lifespan. It gets in through roofs, basements, tanks, and everyday wet areas — and once it’s in, it damages concrete and steel from the inside. We provide waterproofing solutions across residential, commercial, industrial, and infrastructure structures by choosing the right system for each part of the structure, based on where the water comes from and how the space is used.
Roofs and terraces take the most direct hit from sun, rain, and daily temperature swings. Left unprotected, water finds its way through hairline cracks and damages the concrete and ceiling below. We waterproof terraces, roofs, podium decks, expansion joints and large industrial roofs.
We waterproof basements, retaining walls, foundations, and other underground structures that sit below ground, under constant pressure from groundwater and damp soil. If water gets in here, it weakens the foundation and causes lasting dampness.
- A pre-formed sheet membrane, bonded to the structure using pressure-sensitive adhesive.
- Forms a continuous barrier against groundwater; our first choice for basement raft, retaining wall, and foundation waterproofing.
- A flexible sheet membrane, resistant to chemicals and root penetration.
- Used as an alternative to HDPE for basement walls, raft slabs, and underground structures.
- A cement-based coating containing active chemicals that react with moisture in the concrete.
- Forms crystals inside the concrete pores that block water paths from within — permanent, not surface-applied.
We waterproof and protect water tanks, reservoirs, and other water-holding structures under constant pressure, where even a small gap can develop into a leak over time.
- A cement-based system with waterproofing additives, bonded directly to the concrete surface.
- Our standard system for water tanks and reservoirs.
- A two-component spray coating that cures within seconds to minutes.
- Forms a seamless, chemical- and abrasion-resistant layer — suited to tanks needing fast turnaround.
- A two-component resin coating with high chemical resistance.

- Used where a hard, protective, chemically resistant finish is required.
- A non-toxic epoxy or PU system, certified safe for contact with drinking water.
- Used specifically for potable water tanks (OHT, UG sump).
- A synthetic HDPE or PVC liner, welded at the seams for large-area coverage.
- Used for water containment, reservoirs, and industrial ponds.
Bathrooms, kitchens, toilets, balconies, sunken slabs, and utility areas are exposed to water daily, and constant moisture works into the floor and walls if not properly sealed.
- A cement-based coating with waterproofing active chemicals and additives.
- Brush-applied; bonds directly with concrete — our standard system for bathrooms, toilets, kitchens, balconies, and sunken slabs.
- A cold-applied liquid resin, cured chemically without heat or open flame.
- Sets within 30–60 minutes — used for detailed areas and fast-turnaround work.

Waterproofing membranes create seals that prevent water migration between the membrane and the structure in every direction. Preapplied sheet membrane waterproofing that forms an integral bond to poured concrete for horizontal and vertical applications. The pre-applied membranes to adhesively bond to the foundation and shield buildings from water and damaging gas, vapor and moisture.
Two component hybrid polyurethane waterproofing membrane the combination of both these in a specific design ratio creates a liquid hot applied coating for waterproofing applications. Polyurethane is a rather popular choice due to its ease of installation. It is highly reactive and can only be applied by special, two component spray equipment, and spray for general waterproofing applications such as Terrace, Landscaping, car park decks, podium decks and cut and cover tunneling.
Single component hand applied polyurethane membrane system provide an easy, fast and sure system for waterproofing and protection of Old & New roofs, Balconies, terraces and Planter area. These are the kind of membranes that come in the form of liquid that can be sprayed or brushed onto the surface. By spraying, the liquid forms a monolithic membrane, with no laps, welds or seams.
Two component cement based waterproofing and concrete protection system for specialized structures like dams, bridges, culverts, tunnels and all hydraulic structures where the water pressures are very high .It is fully suitable for normal waterproofing requirement of terraces, park places, basement, Swimming pools, sanitary areas etc. When two components are mixed and applied, the film formed is thick elastic membrane with degree of abrasion and chemical resistance. It is most suitable for protection from chloride attacks.
