Concrete Protection

What is Concrete Protection?

This product group offers a complete, premium quality selection of plastic liners that provide perfect protection for concrete

The main focus here is on protecting concrete against environmental influences and aggressive or abrasive media, in order to improve the service life of concrete works.

Concrete protective liners are used wherever a concrete building faces tougher requirements. The main applications for concrete protective liners are, in particular, in transportation and storage of liquids, and where chemical resistance cannot be ignored.

Effective protection for concrete is ensured by the combination of the benefits of special thermoplastic liners (flexible, ductile, no corrosion) with those of concrete (high strength, high stiffness). The concrete is effectively protected therefore prolonging the service life of the structures. Concrete protective liners are therefore a useful option in many concrete building applications, in renovation work, for example. Absolute mechanical anchoring and bridging of cracks in concrete, as well as excellent shear and impact strength and the durability of the liners for concrete protection are just a few of the many benefits.

Concrete protective liners are welded together to create permanent and reliable joints. Depending on the project requirements, butt welding, extrusion and hot wedge welding are necessary for a reliable and leak tight weld, which additionally offers chemical resistance.

World’s first anchored concrete protection

In 1986, AGRU introduced thermoplastic concrete protection
With 40 years of continuous development and field experience, AGRU remains the original pioneer and benchmark for durable concrete protection. Our systems help ensure structural integrity in potable water tanks and reservoirs, wastewater treatment structures, industrial facilities and other concrete exposed to chemical or mechanical stress. This long-term performance makes AGRU’s liners a proven solution for protecting and extending the lifespan of critical concrete infrastructure.

Concrete protective liners

Corrosion protection through chemical-resistant plastics
Reinforced concrete is the material of the 20th and 21st centuries. As robust as reinforced concrete may seem, water and chemicals often find a way to infiltrate the reinforcements, and compromise the stability of structures. Concrete protective liners made of chemically resistant plastics effectively prevent concrete corrosion and therefore extend the life of the structure. They are ideal for buildings with high groundwater backpressure or strict environmental requirements
