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.
Stage 3 : Flood Test
After the UV covering has dried (min 24 hours) flood test is led with a water profundity of 5-6 cm for 48 hours to guarantee no leakage is available in the framework. When the UV covering is totally dried, Our Engineer will visit the site to examine the works finished and give clearness for a flood test (at least 24 hours).
Stage 4 : Geotextile layer
After an effective test, water will be taken out and one layer of geotextile will be approximately laid at a cover of 20 – 30 cm. The geotextile will be reached out up to the vertical surface of the recently applied framework.
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).
Stage 7 : Angle Fillet
Once the screed is completely cured, all of the joints created by the flex cell board will be opened and threatened with ACT sealant with a 20 mm diameter backing rod for accommodating the movement of the concrete. Then, prepare angle fillet (100x100mm) all around parapet skirting and concrete foundations.
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,
1. Polyurethane self-flashing edges
2. Mortar for providing a shape and strength
3. Fabric Reinforcement with a bonding agent on the mortar to prevent cracks
4. Acrylic Coating to provide a final protective layer to the roof
Stage 8 : Backing Rod And Sealant
Once the screed has set Compact Flexy board is cut from the top, a backing rod is put and sealant is applied to seal the expansion joints to give the finest protection to your roof from any leaks.
Stage 9 : Final Coat
After the completion of the joints treatment, curing of the applied angle fillet and the casted screed, saturate the concrete surface with clean water. Two coats of cementitious coating Polyflex (White) will be applied above the surface to avoid the dampness of the substrate. The applied final coat will be allowed to fully cure for 7 days before allowing any traffic on the roof. The topcoat will give an aesthetic appearance to the roof.
