Industrial Grade product, heavy-duty application.
Special formulation for bridge deck applications.
Excellent resistance to puncture.
Robust construction and high tensile strength.
Superior tolerance to thermal shock.
BRIDGE-GUARD SBS membranes are made by saturating and coating reinforcements of spun bond non-woven polyester and glass fibre tissue with a homogeneous thermoplastic blend of SBS (styrenebutadiene-styrene), distilled bitumen and stabilizers. The mixture is carefully produced under controlled conditions to ensure its stability at high temperatures and its flexibility at lower temperatures.
BRIDGE-GUARD SBS membranes are impermeable to water, and are specially formulated to withstand high thermal shock.
QUALITY ASSURANCE & MATERIAL WARRANTY
Imperbit Membrane Industries’ Management system is registered to ISO 9001 standards & all BRIDGE-GUARD SBS membranes carry a 10 year material warranty. In addition to stringent regular test by IMI laboratory, are products are also periodically by independent laboratories.
BRIDGE-GUARD SBS membranes conform to the requirements of ASTM D 6162 Type I & Type II. UEAtc MOAT 27 – 1983 & MOAT 31-1984.
Double reinforced membranes for waterproofing of large decks where dimensional stability of the membrane is important. The combination of polyester and fiberglass mat reinforcement ensures superior shape and dimensional stability under severe cyclic conditions.
The top surface of the membrane is finished with PE film with IMI Logo, fine sand. The bottom surface is covered with a thin layer of printed PE film with IMI design. For exposed application the top surface is covered with a layer of natural slate flakes to protect the membrane from UV rays. The slate flakes are also available in attractive colours on request. The 1 meter wide membranes are produced in thickness of 4 and 5 mm and in a standard length of 10 meters.
