ROOFSEAL is a prefabricated polymer modified bitumen membrane designed for economy and easy applications. ROOFSEAL "P" is reinforced with a non woven polyester fabric, whereas ROOFSEAL "G" is reinforced with a glasfiber mat. The reinforcement is impregnated and coated on both sides with polymer modified bitumen.


ROOFSEAL membrane is ideal for a wide range of waterproofing applications including roofs, basements, tunnels, car parks and resevoirs.

Total impermiability.
Good bondability & seam integrity.
Stability at high temperature. 
Good performance at a broad temperature range.                
Good flexibility.          
Compatible with all normal roofing and building components. 

ROOFSEAL is installed by torch welding method, loose-laid or fully bonded to substrate. When loose-laid, only laps are bonded together. Peripheries and protrusions are sealed according to specifications.


The underside of the membrane should be torched just enough to superficially melt the bitumen. Excessive heating may damage the reinforcement. Overlaps should be reheated from the top and resealed with a trowel to ensure seam integrity.


ROOFSEAL  is available in two basic finishes: 
Black smooth finish with polyethylene surfaces for covered pplications.
Granule surfacing for exposed applications.
