Engineering Scope & Specifications

Certified specialist installation of high-tensile thermoplastic PVC and TPO membranes using robotic hot-air seam welding. Every seam undergoes air-pressure channel testing to ensure leak-free integrity across large roofs, water containment reservoirs, and landscaping planting beds.

Technical Features & Performance

Homogeneous thermal welding stronger than the sheet itself

Certified root penetration resistance

High solar reflectance index (SRI) lowers HVAC load

Long lifespan with low maintenance demands
