POLYGLAS - APP Modified Membrane With Double Re-inforcement


BITUMAT POLYGLAS is an exceptionally high performance, prefabricated, modified bitumen membrane consisting of proprietary waterproofing compound, re-inforced with double re-inforcement of spunbonded non-woven polyester mat and fiberglass mat.

The BITUMAT POLYGLAS proprietary waterproofing compound is formulated with select bitumen, modified with Attactic Polypropylene (APP) for greater elasticity, flexibility, and further enhanced with a blend of Thermoplastic Polymer (TP) and Elastoplastic Co-polymer (EPC) for high heat resistance, greater elongation and low temperature flexibility. The compound is then stabilized with opaque Mineral Stabilizers (MS) for impact resistance, UV resistance and durability.

The superior waterproofing compound is re-inforced with a robust, isotropic, spunbonded, non-woven polyester mat to increase toughness and strength. A second layer of fiberglass re-inforcement is incorporated on the top of the membrane for increased dimensional stability. Combined, they create an exceptionally dimensionally stable, puncture and crack resistant membrane.

The proprietary compound, the unique double re-inforcement, combined with the famous BITUMAT process technology and rigid quality assurance program, yields a very reliable and dependable waterproofing membrane available.


BITUMAT POLYGLAS is the ideal waterproofing membrane for heavy duty requirements such as, large span equipment or traffic bearing roofs, bridges, tunnels, underground tanking, below grade waterproofing or wherever toughness, impact resistance and/or dimensional stability is required.


180 gsm non-woven polyester fabric & 60 gsm of glasfiber mat. Other weights available upon request.


BITUMAT POLYFLEX is available in two basic finishes:

1. Black smooth finish with polyethylene surfaces for covered applications.

2. Coloured granule surfacing for exposed applications.


In addition to stringent regular tests by BITUMAT laboratory, our products are tested periodically by Independent Laboratories.


BITUMAT POLYGLAS complies with the requirements and tolerance levels of:

1. The American Society for Testing & Materials, ASTM D 6223, Type I.

2. UEAtc (European Union of Technical Agreement)


BITUMAT POLYGLAS is installed by torch welding method, loose-laid or fully bonded to substrate. When loose-laid, only overlaps 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 re-heated from the top and resealed with a trowel to ensure seam integrity. For details of installation methods and flashing requirements, consult the relevant BITUMAT Systems Design and Installation Manual.


Bitumat was founded in 1984 but its roots go back to 1975 when the founders became involved in the roofing waterproofing industry as dealer and applicator in Saudi Arabia for a major manufacturer from the U.S.A.
