Concrete Protective Liners


ACROLINE® Concrete Protective Linings outperform traditional coatings and traditional linings in aggressive acid and caustic environments. ACROLINE® Systems are a suite of thermoplastic semi-finished products, which are welded or fused together to form custom-designed single or dual layer liners for concrete structures. This type of lining provides a chemical-resistant, leak-tight barrier to contain environmentally hazardous materials or to protect concrete structures from chemical attack. The anchored concrete protection liners are mechanically locked into a cement substrate to resist thermal expansion and contraction and groundwater pressure. The high elongation of thermoplastics and mechanical anchoring system of the ACROLINE® concrete protection liner allows the liner to bridge cracks in the substrate. Some areas of use for ACROLINE® concrete protective linings are:

  • Containment Areas
  • Flooring Systems
  • Trenches
  • Sumps
  • Foundations
  • Manholes and Lift Stations
  • Process Vessels
  • Sewer Pipe Rehabilitation
  • Storage Tanks



  • Mechanically anchors into concrete
  • New lining can be placed into chemical service immediately after welding – No 28-day cure required, as with coatings
  • Ideal for new construction or where retrofits are needed
  • Works in conjunction with standard concrete practices
  • Meets EPA requirements for dual containment with leak detection system
  • Liner bridges cracks in concrete substrate, maintaining containment and corrosion protection
  • Superior chemical resistance
  • Anchored sheet is manufactured in a single process with no interface between the anchors and the sheet
  • Liner system has a long design life and is maintenance-free and repairable
  • Dual-wall ACROLINE® System liner provides integral secondary containment and leak monitoring capability
  • Provides a continuous system when welded to piping of same resin
  • Can be prefabricated and preformed
  • Trench systems can also be fabricated to any size or shape to provide a positive tie-in with flooring systems
  • A variety of thicknesses and plastics are available to meet your thermal and chemical resistance requirements
