External and internal basement tanking using crystalline waterproofing, cavity drain membranes, bentonite clay panels, and bituminous sheet membranes for below-grade structures.
Transparent silane-siloxane water repellents and cementitious coatings for exterior walls to prevent dampness, efflorescence, and plaster peeling caused by monsoon rains.
Food-grade crystalline waterproofing for overhead and underground water tanks. Safe for drinking water. Prevents leakage, algae growth, and structural degradation.
Cementitious and liquid membrane systems designed to handle hydrostatic pressure and chemical exposure. Suitable for residential and commercial swimming pools.
Polyurethane and epoxy resin injection for structural cracks, expansion joints, and active leak sealing. Expands on water contact to form a permanent, flexible seal.
Waterproofing for kitchen floors, utility areas, balconies, and sunken slabs to prevent water seepage into lower floors and protect structural integrity.
Every project uses premium, factory-tested materials applied by trained technicians following a standardized quality process.
Two-component polymer-modified coating that forms a rigid, durable waterproof barrier. Ideal for wet areas, water tanks, and basements. Bonds chemically with concrete substrates.
Seamless, flexible polyurethane membrane for exposed roofs and terraces. UV-resistant with excellent crack-bridging properties. Service life of 8-12 years.
Advanced chemical treatment that penetrates concrete pores and forms insoluble crystals, creating a permanent watertight barrier with self-sealing properties.
Torch-on or self-adhesive modified bitumen sheets for basement tanking, foundation waterproofing, and below-grade applications.
Low-viscosity polyurethane resin injected under pressure into cracks. Reacts with water to expand and form a flexible, watertight seal.
Highly elastomeric reflective coating that reduces interior temperatures by 3-5 degrees Celsius. Extends roof life and reduces energy costs while providing waterproofing.
