For Maximum Concrete Protection

Concrete Protective Liners (CPL)

AGRUSAFE Concrete Protective Liners (CPL) are specifically designed to offer a robust defense against concrete corrosion and abrasion. Utilizing high-grade thermoplastics, namely HDPE, PP, PVDF, and ECTFE, these CPLs are adeptly tailored for a range of demanding environments. This includes applications such as lining drinking water reservoirs, ensuring durability in deep sewer tunnel infrastructures, and safeguarding building foundations. Exhibiting a notable pull-out resistance reaching up to 80 tons per square meter and a capacity to counter water backpressure as high as 1.75 bar, these liners underscore a commitment to longevity and performance. Whether integrated into cast-in-situ or chosen for precast concrete applications, AGRUSAFE CPLs ensure enhanced structural protection and extended service life.

Application Examples

AGRU Ultra Grip

Concrete Protective Liner (CPL)

The AGRU Ultra Grip Concrete Protective Liner (CPL) features a unique conical stud configuration for ultra strong anchoring in the concrete structure. With a pullout force of 80 tons per square meter, this HDPE concrete protective liner effectively withstands groundwater pressures up to 1.75 bar (at 20°C). For large concrete structures, the available 5 m wide sheets from AGRU streamline installation, reducing required welds by up to 60%. Enhanced abrasion resistance ensures AGRU-Ultra Grip’s prolonged durability and service life.
