Concrete Roof Mechanical Fixation Method	Metal Roof Waterproofing	Roofing Details Treatment	Self Adhesive Polymer Waterproof Membrane Application for Concrete Roof

The installation of TPO waterproofing membrane is combined with advanced and mature technology , and complete application . Hot air welding is adopted for the overlaps of membranes, and between membrane and prefabricated accessories . The Installation are basically categorized as ballasted system, full adhered system and mechanical attachment system .

Ballasted System

The membrane is installed by adhesive or metal battens at certain area .The remaining area is not attached . Overlaps is welded by hot air. The wind uplifting force is withheld by the weight of ballasted materials .

System Features

. Suitable for all types of different substrates

. Quick installation

.Low Installation cost ;

.Excellent weathering resistance

The installation method is suitable for green roofs , driving roofs , the often step roof and non-often step roofs covered with cobble stones or prefabricated blocks.

Fully -Adhered System

The TPO membrane is adhered to base with adhesive . Overlaps is welded by hot air .

System features

. For roofs with complicated structure;

. Light weight ;

. Strong wind uplift resistance ;

. Great looking

The installation method is suitable for concrete roofs and steel roofs with high density insulation boards .

Mechanical Fixation System

The roofing membrane is installed by special roofing screws with plates or battens to the basis like structural concrete ,steel deck or wooden deck ,etc. The Overlap between the seams of the membrane sheet is welded by hot air welder .
