Concrete Protection Liners
Sangir Concrete Protection Liners are meant explicitly for lining Cement/Concrete pipes, tanks, chambers, and other structures, internally and externally. These are manufactured in two materials of construction, blended polyethylene (PE) and Polypropylene (PP). These are installed when concreting itself, and the V-Type or T-type anchoring gets permanently embedded and fixed in the concrete surface, forming a permanent bonding with the substrate. Sangir concrete protective liners provide excellent and cost-effective solutions for protecting concrete surfaces against attack from adverse chemicals, biological hydrogen-sulfide, and other chemicals in the flow media. These isolate the concrete structure suitably to ensure that Concrete-corrosion or erosion does not take place and the operational life of the systems is extended appropriately.
