· Excellent Dimensional stability
· Cost effective waterproofing membrane
· High resistance to perforation & tear
· Good elongating and recovery properties
· Exceptional bonding to substrate and at seams.
POLYGARD membranes are made by saturating and coating a robust reinforcement of 180 & 200 grm/m2 non woven spun bond polyester with a homogeneous thermoplastic blend of APP (Atactic Polypropylene), distilled bitumen and stabilizers. The mixture is carefully produced under controlled conditions to ensure its thermal stability at high temperature and flexibility at low temperature.
POLYGARD membranes are impermeable to water, easy to apply and available with the option of a granule finish for exposed use.
QUALITY ASSURANCE & MATERIAL WARRANTY
Imperbit Membrane Industries’ Management system is registered to ISO 9001 standards & all POLYGARD membranes carry a 10 year material warranty. In addition to stringent regular test by IMI laboratory, our products are also tested periodically by independent laboratories.
POLYGARD membranes conform to the requirement of UEAtc & ASTM.
SURFACE FINISH AND SIZE OF ROLL
The top surface of the membrane is covered with a thin layer of PE film or sand. The bottom surface is covered with Printed PE film with IMI design. The membranes are produced in thickness of 4 mm and 5 mm and in a standard length of 10 mtrs and 1 mtr width.
