The system with Polyurea Rayston X5 with topcoat Impermax A has just obtained the Broof(t1) certificate of behavior to an outdoor fire. This system also has an asbestos encapsulation certificate.

Polyurea Rayston X5 is an expandable polyurea that, when it cures, forms a totally continuous coating, adhered to the support, waterproof, highly resistant, elastic and flexible, that is, with an excellent ability to bridge possible cracks in the support.

This solution is designed to solve waterproofing problems at a much lower cost compared to standard polyurea systems (see table). This allows them to gain in waterproofing quality and compete in price with traditional systems based on asphalt fabrics.
