• • Roof tiles not required

• • Time efficient system

Application process 

1. SITE PREPARATION :
Upon casting and complete curing of roof slab, ADEM’s Engineer shall visit the site to inspect the roof and accept the roof for waterproofing and heat insulation works. A preliminary site inspection shall be carried out and any further preparation work if required shall be brought to the attention of the main contractor.

2. PU APPLICATION : 
Upon completion of cleaning, spray application of the 1st shall commence where a combination of POLYOL and MDI is sprayed onto the roof slab. The spray applied foam in liquid state hits the slab at a high pressure and penetrates into every crack and pin holes that exist on the slab. In minute it expands 30 times its volume and solidifies thereby sealing the entire substrate. The foam creates an impermeable waterproofing cum insulation layer with high thermal resistance, closing all pores and cracks that exists in the roof slab. 

3. UV PROTECTION COATING :
On completion of polyurethane foam application, rubberized bituminous or acrylic liquid  UV protection coating shall be applied over entire foam to protect it from UV rays till the water test procedure is completed.

4. FLOOD TESTING THE ROOF : 
Once bituminous or acrylic UV coating is completely dried (minimum 24 hours), our Engineer will visit the site to inspect the works completed and give clearance for flood text (minimum 24 hours). On successful completion of flood test a test report shall be prepared and maintained for records.

5. PANELLING AND SCREED LAYING :
Upon successful completion of flood test, water shall be removed and  GEOTEXTILE (100gsm) membrane shall be laid as a protection layer over the entire roof area and our crew will do the paneling work using expansion joint filler board and pre-mixed cementitious adhesive mortar to attain the desired slope levels prior to commencement of screeding works.
Protective screed of 300OPC 10mm aggregate, 25N/mm² strength screed will be laid in panels. Minimum thickness of the screed will be 45mm and average thickness will be 80mm. The screed will be finished manually by our trained masons and cured as per standard procedures. The screed is added with plasticizers and micro fibres to avoid crack.

6. ANGLE FILLETS AND JOINT TREATMENTS : 
Angle fillets are done after application of bonding agent to the corners of size 100x100mm. Once screed is completely cured, all construction joints shall be opened and treated using heavy duty PU SEALANT and backing rod for accommodating movement of the concrete during expansion and contraction. 

7. FINISHING : 
Once sealant applied is completely cured, the contractor can choose from any of the three finishing coatings as per project specification or as preference – acrylic polymer modified cementitious,  highly elastic liquid waterproofing styrene acrylic emulsion coating, or  PU COATING aliphatic polyurethane coating, shall be applied over entire screed including upstands to form a uniform coating of maximum thickness 1000 microns. This coating provides an aesthetic look to the roof.
