Waterproofing is the process of applying a protective barrier to prevent water infiltration. In Chennai, the coastal climate, heavy rainfall and humidity make waterproofing essential to avoid seepage, mole, corrosion and structural damage.

Poor application, substandard materials, structural movement, UV damage, clogged drainage and lack of maintenance are common causes. Using trusted materials like Golden Building Chemicals and expert application can prevent failure.

Yes, EMERGE INFRA specializes in retrofit waterproofing. We use injectable PU grouts, surface coatings, bitumen treatments and chemical treatments that work effectively even on old or damaged structures.

No. It requires regular maintenance and inspections, especially in exposed or high-use areas. Our Annual Maintenance Contracts (AMC) ensure long-term protection and system longevity.

Yes, we provide warranties ranging from 3 to 10 years, depending on the system and scope. Warranties certified systems and are extended further under our AMC plans.

It is far more cost-effective than repairing water damage. Prices depend on area size, method and materials. We offer customized packages for all budgets.

Paint peeling, wet spots, water stains, mole, foul odour and rust on reinforcements are common signs that waterproofing may have failed.

We recommend chemical coatings for terraces and roofs due to their flexibility, UV resistance and seamless application.

Yes. After surface cleaning and priming, liquid-applied membranes can be applied over tiles. This avoids breaking existing surfaces.

It's a preventive system applied directly on the structural roof slab (before screed and tiles) to ensure base-level moisture protection. It’s a must for long-term building health.

We use PU sealants and backer rods from Golden Building Chemicals for expansion joints, ensuring flexibility and water-tightness.

We apply GBS cementitious coatings on sunk slabs and walls, use PU sealants in joints and finish with epoxy grout between tiles.

Sunkun waterproofing treats the recessed area below bathroom floors. This zone is prone to leakage to lower floors and must be waterproofed thoroughly before tiling.

It involves waterproofing the parent concrete layer before any plastering or floor layers are added, ensuring protection from the inside out.

We clean and prep the surface, apply GBS crystalline or cementitious waterproofing, seal joints with PU and conduct water tests for confirmation.

Yes. We remove damaged plaster, repair cracks with injection grouting and apply food-safe GBS coatings for internal tank walls and floors.

It involves waterproofing the parent concrete layer before any plastering or floor layers are added, ensuring protection from the inside out.

We recommend checking them every 2–3 years and renewing coatings every 7–10 years or as per usage.

After cleaning and crack repair, GBS elastomeric wall coatings are applied. These protect from rainwater penetration and weathering.

Yes. It’s ideal to apply waterproofing during construction to protect hidden surfaces like mother slabs, underground pits and vertical walls.

We remove loose plaster, apply waterproof base coat, re-plaster and finish with a UV-resistant waterproof paint system.

We use injection grouting with PU, followed by cementitious or crystalline coatings. Drain outlets are sealed with elastomeric compounds.

We apply a combination of negative side waterproofing, crystalline treatment and sealants to block seepage from foundations, pits, or retaining walls.

Yes. It prevents water rise due to capillary action, protecting the structure’s base from long-term damage.

A flexible, waterproof and UV-resistant coating used on terraces, podiums and concrete roofs. It expands and contracts with temperature changes.

For larger areas like roofs and bridges, especially in industrial or low-maintenance applications. GBS bituminous membranes offer durability and water resistance.

• PU Grouting: Flexible, for active leaks.
• Epoxy Grouting: Hard and rigid, for cracks in dry conditions.
• Cementitious Grouting: For static sealing under pressure.

A self-healing chemical treatment where crystals grow within concrete pores to block water paths, ideal for tanks, basements and sumps.

Regular inspections, minor repairs, re-sealing joints, touch-up coatings, drain cleaning and performance checks. AMC ensures leak-free property maintenance.

Yes. It reduces emergency repair costs, ensures warranty compliance and extends the life of the waterproofing system.

Yes. AMC is offered in quarterly, bi-annual, or annual packages, depending on your building type and waterproofed areas.

Yes. We handle waterproofing for villas, apartments, schools, hospitals, industries, commercial buildings and more.

We conduct a free site assessment, check moisture levels, surface conditions, existing treatments and propose the best GBS-based system.

Depending on the system:

• PU coatings: 24–48 hours
• Cementitious: 72 hours
• Tanks: 5–7 days before refilling

Yes. We provide photo reports, service checklists, material data sheets and warranty documents for all projects.

We inspect and repair it free of charge as per the terms of your warranty or AMC plan.

We offer priority leak support in Chennai within 24–48 hours, especially during monsoons.
