Stage 1 : Application of PU Foam
The spraying movement will just initiate after the definite Inspection. Utilizing Spray Foam Machine, a combination of Polyurethane material, for example, Polyol and Iso PMDI is applied on the readied surface. The spraying will be done in level or vertical ways in layers before accomplishing a thickness. The polyurethane foam of density 45 Kg/m3 is spraying on the cleaned rooftop slab, this spraying finds a way into the tightest of cracks and edges and seals them. The actual foam requires 30 seconds to solidify and shape a defensive protection and waterproofing layer. The foam is spraying in various layers of thickness 10-15 mm to accomplish the ideal thickness.
Stage 2 : Application RBE Coating
After the Foam Application, single segment acrylic-based high adaptable elastomeric water-confirmation covering RBE is applied to the whole surface of the polyurethane foam. Permit the Protective covering to dry for at least 8 hours relying upon the site Condition. Endless supply of PU foam application, a layer of 600-800 Microns of fluid Compact UV Protective Coating is applied to shield the Polyurethane from harmful UV radiation.

Ridges Combo Roof System UAE
Stage 5 : Ridges
after geotextile, the rooftop is isolated into 3m X 3m Sections utilizing Compact Flexy Board to give incline and development joints to the rooftop. We prescribe our esteemed clients to put a Rain Water Outlet every 100 m2. Endless supply of Geotextile, the rooftop will be compartmented to rectangular or square shape at 6m2 (max) utilizing a 12mm thick flexcell board. The ideal Slope is changed with the flexcell board. The flexcell Board will be fixed over the geotextile by sand concrete mortar to keep it in a vertical position
Stage 6 : Screed Laying and Leveling
Once the Ridges are made our experienced masons lay and level the screen to provide the perfect slope for a perfectly finished roof. The screed is 20N/mm2, 250 OPC, 0.6 Kg/m3 Fiber-reinforced screed concrete to provide the best protection and minimal cracks. After the paneling works, a Protective screed of 20 N/mm2 strength screed will be laid in panels with an average screed thickness of 80mm. The screed will be smoothly finished and cured for 2 days (minimum).

The Skirting of the roof is protected using mortar to give a good finished look to the roof and also protect the system underneath. This is achieved in 4 layers,
- Polyurethane self-flashing edges
- Mortar for providing a shape and strength
