Sure-Grip® concrete protective liners made of HDPE, HDPE-el, PP, PVDF and ECTFE are produced with state-of-the-art manufacturing technology. This system has been successfully applied worldwide for more than 25 years and serves as a long-term alternative to spray-applied concrete protection products.
Sure-Grip prevents concrete corrosion and degradation and can substantially extend the lifetime of a structure. In addition, by preventing ex-filtration and infiltration, concrete protective liners provide direct protection for the environment and increased operating efficiencies. Furthermore, the unique anchoring system also enables construction in areas of significant back-pressure. Unlike spray-applied liners, which have to be reapplied regularly due to cracking or delamination, concrete protective liners are long-lasting. The reapplication of spray liners presents residuals cost with significant effort to empty and clean the tank as well as operational downtime.
Concrete protective liners combine the advantages of thermoplastics (flexible, ductile, corrosion resistant) with those of concrete (high strength, high stiffness). Thus, the concrete is protected effectively and the durability and life expectancy is increased.
Innovative Design for Leak-Proof Constructions
The unique V-shaped anchor studs, which are integrally formed onto the liner during the extrusion process to allow a secure mechanical anchoring of the concrete protective liner to the concrete guaranteeing optimum anchoring to the concrete. Depending on the specific project requirements, a variety of anchor designs, resins, and liner thicknesses and colors are available. Concrete protective liners are joined by welding which provides permanent and reliable joints. Different welding technologies, depending on the project requirements, are available for a secure and leak-proof joint:
- Butt welding
- Extrusion welding
- Hot wedge welding
- Hot gas welding
