Ethylene Propylene Diene Monomer or Terpolymer (EPDM)

Thoroughly inspect substrate condition and environmental factors including wind speed, humidity levels, and surface moisture content, ensuring all parameters comply strictly with manufacturer’s specifications before proceeding.

Precisely spray-apply the polyurethane foam in multiple passes to achieve the required thickness, creating a seamless, self-bonding insulation layer across the entire deck.

Apply a UV-resistant protective base coat over the cured foam to seal the surface and provide an immediate waterproof secondary shield.

Install a separation layer of non-woven geotextile followed by the formation of precise slopes using lightweight screed to ensure efficient water drainage.

Lay the protective concrete screed to specified gradients, providing a durable walking surface and mechanical protection for the underlying layers.

Detail all critical areas, including expansion joints and wall-to-floor junctions, with specialized sealants and cementitious coving to eliminate leak-prone corners

Apply the final, heavy-duty waterproof membrane over the finished screed and parapets for a complete, multi-layered customization of the roof’s defense system.
