BITUMAT TOPSEAL 200 is a uniquely formulated prefabricated waterproofing membrane with a special multilayered design for superior pliability, tensile strength, workability and resistance to elements.
The multilayered design consist of a spunbonded polyester core coated on both sides with APP modified bitumen. The polyester core gives the membrane high tensile strength, elongation and superior lap joint strength.
Properly installed, BITUMAT TOPSEAL 200 forms an impervious, permanently flexible waterproof blanket which accepts normal structural movement without breaking or cracking.
BITUMAT TOPSEAL 200 membrane is ideal for a wide range of waterproofing applications including roofs, car parks, reservoirs, etc
BITUMAT TOPSEAL 200 is available in two basic finishes:
1. Black smooth finish with polyethylene surfaces for covered applications.
2. Granule surfacing for exposed applications.
In addition to stringent regular test by BITUMAT laboratory, our products are tested periodically by Independent laboratories.
BITUMAT TOPSEAL 200 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.
Gas torch, knife, trowel, measuring tape, marking strings and gloves.
(Rate may vary as per site requirement)
Flat areas : 1.15 m2/m2 per layer with 10 cm. side laps and 15 cm. end laps Base flashing : 100x35 cm. with 15 cm. end laps, 0.40 m2/ Linear Meter Average wastage : 3 - 5 %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 Bitumat technical department.
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.
