PU Waterproofing Coatings for Extreme Weather & Chemicals PU coatings offer a high-performance waterproofing solution for structures facing extreme weather, moisture, and chemical exposure. Suitable for rooftops, terraces, wet zones, and tunnels, these coatings cure into an elastomeric membrane that remains flexible and crack-resistant over time. Their seamless finish prevents leaks and withstands UV degradation, thermal movement, and aggressive conditions. Ideal for industrial and commercial buildings, our PU systems provide long-lasting protection and cost efficiency with minimal maintenance needs.
