Overview

Polyurethane (PU) waterproofing is a seamless, high-performance waterproofing solution that offers superior flexibility, durability, and weather resistance. It is widely used for rooftops, balconies, terraces, podiums, and industrial structures, where exposure to extreme weather, UV rays, and structural movements require a flexible yet robust waterproofing system.

Unlike traditional cementitious or bituminous waterproofing, PU coatings form a rubber-like, elastic membrane that adapts to thermal expansion, surface cracks, and high foot traffic, making it ideal for residential, commercial, and industrial applications.

Best for:

✔ Rooftops & Terraces – Provides long-lasting waterproofing with UV resistance.
✔ Balconies & Podiums – Ensures flexible and crack-resistant protection.
✔ Parking Decks & Industrial Floors – Withstands heavy loads and traffic.
✔ Bridges & Infrastructure – Offers resistance against environmental stress.
✔ Waterproofing for Complex & Irregular Surfaces – Ideal for domes, curved structures, and industrial units.

How it Works:

1️⃣ Surface Preparation – The substrate is cleaned, leveled, and primed to ensure proper adhesion. Any cracks or damages are repaired before application.
2️⃣ Application of Primer – A polyurethane-based primer is applied to enhance adhesion and waterproofing effectiveness.
3️⃣ PU Membrane Coating – Multiple layers of liquid PU membrane are applied using a brush, roller, or spray, ensuring even coverage.
4️⃣ Curing & Drying – The PU membrane is left to dry, forming a flexible and seamless waterproofing layer.
5️⃣ Optional Protective Coating – In some cases, an additional UV-resistant or wear-resistant topcoat is applied for extra durability.

Benefits:

✅ Superior Flexibility & Crack Bridging – Expands and contracts with structural movements, preventing cracks and failures.
✅ Seamless & Waterproof Barrier – Eliminates weak points where water can penetrate.
✅ Resistant to UV Rays & Harsh Weather – Long-lasting performance in outdoor environments.
✅ Chemical & Abrasion Resistant – Ideal for high-traffic areas and industrial applications.
✅ Lightweight Yet Highly Durable – Does not add extra load to structures while ensuring excellent waterproofing.
✅ Quick Application & Fast Drying – Reduces downtime and labor costs.
