(ii) Providing and laying/fixing TPO (Thermoplastic Polyolefin) waterproofing membrane (min 1.2mm thickness) on prepared surface of roof & up to 300 mm of parapets and crumple joint including junction of roof and parapet. Method: TPO membrane is mechanically anchored in the roof deck using fasteners and washers, which are then overlapped with TPO membrane and heat welded. The overlap completely encapsulates the fastener, which is not exposed to any external weathering ensuring no water, heat seeps into the insulated panel. The roof edges of the building are covered with TPO edge trims, mechanically anchored and heat welded with TPO on top thus completely encapsulating the system, preventing any wind from blowing beneath the TPO or roof. Review attached methodology to understand the system. Providing and fixing Smartcare TPO Membrane Single PLY -FR is a high performance, heat weldable, thermoplastic polyolefin (TPO) sheet, manufactured, designed for waterproofing and heat shielding roofs of new and existing buildings.
