Polyurethane Waterproofing Coating is a liquid-applied protective coating that forms a continuous, flexible, and water-resistant membrane after curing. It is designed to protect concrete and other suitable substrates against water penetration, moisture ingress, and environmental exposure.
Its seamless application allows the coating to cover irregular surfaces, corners, joints, and detailed areas where conventional waterproofing materials may require additional detailing. Depending on the formulation, polyurethane waterproofing coatings can provide flexibility, crack-bridging capability, abrasion resistance, and durability for a range of construction applications.
GeoTech Lining PVT LTD provides Polyurethane Waterproofing Coating solutions for construction projects requiring reliable surface protection and moisture control. These coatings can be applied to suitable prepared substrates to create a continuous waterproofing layer across roofs, terraces, balconies, foundations, and selected concrete structures.
The coating system should be selected according to the substrate condition, exposure to sunlight, expected movement, water exposure, and project requirements. Proper surface preparation, application thickness, and curing are essential for achieving effective waterproofing performance.
Polyurethane coatings are available in different formulations for exposed roofs, protected waterproofing systems, and other construction applications. The appropriate product depends on the substrate, service conditions, required flexibility, and intended protective finish.

We provide reliable installation services for projects of all scales and industries. From material selection to final quality checks, we collaborate closely with our clients to ensure a precise, durable, and long-lasting liner installation.
We assess the substrate condition, existing coating or waterproofing layers, moisture levels, drainage, exposure conditions, and project requirements to determine a suitable waterproofing approach.
The appropriate polyurethane coating is selected according to the application area, expected movement, sunlight exposure, water conditions, substrate compatibility, and required protective finish.
The surface is prepared, and compatible primers or reinforcement materials are applied where specified. The coating is installed at the required thickness, with particular attention to corners, joints, outlets, and penetrations. Application conditions, curing, and final coverage should be checked according to the product instructions.
Roofs and terraces are regularly exposed to rainwater, temperature changes, and direct sunlight. A suitable polyurethane waterproofing coating creates a continuous protective layer that helps reduce water ingress through properly prepared surfaces. Geotech Lining PVT LTD offers complete guidance.
Typical applications:
Concrete roofs
Flat roofs
Roof terraces
Exposed concrete slabs
Roof upstands and detailed areas
For exposed roofs, select a formulation designed for UV and weather exposure. Where required, use a compatible protective topcoat and ensure the roof has adequate drainage.
Balconies, bathrooms, and other wet areas require effective waterproofing beneath their finished surfaces. Polyurethane coating systems can provide a continuous waterproofing layer when the product is suitable for the intended installation.
Typical applications:
Balconies and verandas
Bathrooms and washrooms
Utility and laundry areas
Wet rooms
Suitable tiled or tiled-to-be installations
Confirm compatibility with adhesives, screeds, tiles, drains, and other system components. The coating must be installed according to the specified requirements before covering it with the final finish.
GeoTech Lining PVT LTD provides Polyurethane Waterproofing Coating solutions for construction, commercial, and selected industrial applications. From roofs and terraces to balconies, foundations, and concrete surfaces, choosing a suitable coating system and applying it correctly helps protect structures against water ingress and moisture-related damage.
Commercial and Industrial Projects
Industrial roofs
Commercial buildings
Selected plant and utility areas
Concrete surfaces requiring moisture protection
Renovation and Maintenance
Refurbishment of suitable existing concrete surfaces
Waterproofing repairs as part of a designed system
Protection of compatible substrates
Recoating projects where the existing surface is suitable
Below-ground structures may be exposed to groundwater, damp soil, and moisture pressure. Suitable polyurethane waterproofing systems can help protect foundation walls and selected basement surfaces against water penetration.
Typical applications:
Basement walls
Foundation surfaces
Retaining walls
Underground structures
Selected concrete service areas
Below-ground use requires careful assessment of water pressure, substrate moisture, soil conditions, and protection during backfilling. A coating should only be used where it is designed for the relevant exposure and installation conditions.
Geotech Lining PVT LTD team knows about certain polyurethane coating systems can be used to protect suitable concrete surfaces exposed to water. The product must be specifically appropriate for the intended service conditions.
Typical applications:
Selected concrete water-retaining structures
Concrete channels
Service areas exposed to moisture
Suitable industrial concrete surfaces
For potable-water tanks, swimming pools, or continuous immersion, verify that the coating is specifically approved for the intended exposure. General-purpose polyurethane coatings should not automatically be assumed suitable for drinking-water contact or permanent immersion.
GeoTech Lining PVT LTD has successfully installed a diverse range of Geo-synthetic applications, ranging from small farm dams to canal lining and complex floating.
