Liners

Concrete Protective Liners

In harsh industrial environments, concrete alone isn’t enough. Our mechanically anchored concrete protective liners are engineered to safeguard against aggressive chemicals, prevent leaks, and extend the life of your infrastructure. Whether you're working with tanks, pits, or containment areas, Plastek Werks delivers long-term protection you can trust.

Why Use a Concrete Protective Liner?

Pharmaceutical Trench Liners with
Conductive Tape for Weld Testing

• Chemical Resistance – Withstands acids, caustics, and aggressive process fluids
• Leak-Tight Barrier – Creates a continuous, sealed surface to prevent seepage
• Anchored for Strength – Mechanical studs lock the liner into place, bridging cracks and resisting delamination
• Long-Term Value – Outperforms coatings and traditional liners in durability and lifespan
• Custom Fit – Fabricated and installed to match your structure’s exact dimensions
