Perfect all purpose protection for sub grade concrete.
Excellent elongation and recovery properties.
Superior flexibility and pliability.
Exceptional bonding strength to self and substrates.
Easily workable around protrusions and profiles.
Unaffected by corrosive salts and dilute acids found in ground water.
IMPERFLEX membranes are made by saturating and coating a reinforcement core with a homogeneous elastomeric blend of SBS (Styrene-Butadiene-Styrene), distilled bitumen and stabilizers. The elastomeric compound is carefully produced under controlled conditions to ensure stability at atmospheric temperatures and flexibility even at very low temperatures. IMPERFLEX membranes are impermeable to water, very flexible and easy to work around contours and protrusions.
QUALITY ASSURANCE & MATERIAL WARRANTY
Imperbit Membrane Industries’ Management system is registered to ISO 9001 standards & all IMPERFLEX 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.
IMPERFLEX membranes conform to the requirement of UEAtc MOAT: 31 – 1984, MOAT 64: 2001 and tested in accordance with UEAtc MOAT 27 – 1983, ASTM D5147.
A variety of reinforcement cores are used in the productions of the IMPERFLEX range, these include 180, 200, 250 & 270 gr/m² spun bond polyester, glass fiber tissue and a combination of the two.
The top surface of the membrane is finished with PE film, fine sand or Black Quartz. The bottom surface is covered with a thin layer of 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 3, 4 and 5 mm and in a standard length of 10 meters. (Base sheets are produced in 2 mm thickness and in length of 20 mtrs)
