PolySeal Geoliner

PolySeal is an elastomeric polymer barrier liner engineered for water containment and sealing applications across civil infrastructure and mining environments. Applied as a spray-on geoliner in three coats, PolySeal forms a seamless, highly flexible membrane that conforms to any surface shape or size, making it suitable for earthen dams, concrete reservoirs, canal structures, and containment ponds across India’s water, irrigation, and mining sectors.

At its core, PolySeal is a polymer modification of cement, combining elastomeric cross-linking polymers with Portland cement and non-plastic aggregates to produce a composite material with significantly higher tensile and flexural strength than standard cement mortar. Where conventional concrete and mortar are brittle and prone to cracking under settlement or thermal movement, PolySeal’s elastomeric nature allows it to flex without fracturing, extending the service life of both new structures and rehabilitated existing ones.

How PolySeal Works

PolySeal is a water-soluble polymer emulsion applied in three successive coats to concrete or earthen surfaces. Each coat penetrates and bonds to the substrate before the next is applied, building up a highly elastic, non-toxic, and seamless waterproofing membrane. The three-coat system ensures full coverage without joins or seams, which are the primary failure point of sheet-based liner systems.

Key Benefits

Seamless membrane — Applied as a liquid, PolySeal eliminates joins, overlaps, and seams, removing the most common point of failure in conventional liner systems.

Flexible and crack-resistant — The elastomeric polymer does not become brittle after curing. It flexes under structural movement and thermal expansion without cracking or delaminating.

UV and weather resistant — PolySeal withstands prolonged UV exposure and all-weather conditions, maintaining its integrity across India’s varied climate zones from coastal humidity to Rajasthan’s dry heat.

Fire resistant — PolySeal is resistant to grass fires, an important consideration for above-ground containment structures and waste capping in open environments.

Conforms to any shape — As a spray-applied liquid, PolySeal lines irregular surfaces, curved walls, and complex geometries that sheet liners cannot accommodate without cutting and joining.

Easily repairable — Damaged sections can be recoated without removing or replacing the existing membrane, significantly reducing maintenance costs over the structure’s lifetime.

Non-toxic — Safe for potable water storage and freshwater aquaculture applications.

Typical Applications

• Freshwater dam lining, for both new construction and rehabilitation of earthen and concrete dams
• Mine tailing dam lining and containment, sealing toxic and chemical waste ponds in compliance with environmental regulations
• Canal lining and repair, suitable for state irrigation canal networks and PMKSY scheme infrastructure
• Concrete reservoir repair and waterproofing, restoring failing water storage structures without full demolition
• Barrier liners for toxic and industrial ponds, with chemical resistance across a range of industrial effluents
• Capping of toxic waste stockpiles to prevent leachate migration and dust emission
• Aquaculture pond lining, a non-toxic membrane suitable for fish and prawn farming pond construction
