Bitumen & PU Chemical Coating in Chennai
Two of the most trusted waterproofing materials in the industry, chosen for durability and resistance to weathering and UV exposure.
Overview
What Is Bitumen & PU Chemical Coating?
Bitumen membranes and polyurethane (PU) coatings are both proven, high-performance systems, each suited to slightly different situations. Bitumen membranes — torch-on or self-adhesive — offer excellent resistance to water, weathering, and UV exposure for large flat areas.
PU coatings, by comparison, offer greater flexibility and are easier to detail around complex shapes. We select — or combine — bitumen and PU based on the surface, exposure, and finish requirements of your specific project.
This service is ideal if:
Large flat roofs and terraces (bitumen membrane)
Complex or detailed surfaces (PU coating)
Foundations and basements needing tough membrane protection
Projects wanting a proven, long-track-record material
Why It Matters

Effective across roofs, basements, and foundations alike, making it a versatile choice for mixed-scope projects.
Our Approach
Techniques & Materials We Use
Torch-On Bitumen Membrane
Heat-applied bitumen sheet membrane bonded directly to the primed surface.
Self-Adhesive Bitumen Membrane
A cold-applied bitumen option for sites where torch application isn't practical.
Liquid PU Coating
A brush or spray-applied polyurethane coating for flexible, seamless coverage.
Primer & Detail Work
Surface priming and detailed sealing at edges, upstands, and penetrations before the main coat.
FAQ
