Understanding the Environmental Challenges

The GCC region, and specifically Saudi Arabia, presents one of the most challenging environments in the world for concrete structures. The combination of intense heat, high humidity, groundwater salinity, and thermal contraction places extreme stress on concrete foundations and roofs.

Without adequate protection, water ingress can rapidly lead to structural deterioration, reinforcement corrosion, and concrete spalling, significantly shortening the lifespan of commercial and residential assets.

The Role of Liquid-Applied Polyurethane

Traditional sheet membranes are often prone to joint failures under high temperature cycles. Liquid-applied elastomeric polyurethane membranes, such as CICOPROOF® WEP, offer a seamless solution. These systems adhere directly to the substrate, leaving no room for water to migrate beneath the membrane.

Furthermore, technology transfers from global leaders like Soprema allow local manufacturers to refine polyurethane coatings, ensuring they maintain elasticity at temperatures exceeding 70°C on exposed roofs.

Best Practices for Specifiers

• Surface Preparation: Concrete must be thoroughly cured and free of laitance or dust before application.
• Priming: Always apply a dedicated primer (e.g., CICOPRIME®) to seal the pores and eliminate pinholes.
• Thickness Control: Ensure a consistent wet-film thickness to guarantee long-term elastic performance.
