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. ACROLINE Liner Systems provide 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 cementitious substrate to resist thermal expansion and contraction and groundwater pressure. The high elongation of thermoplastics and mechanical anchoring system of the ACROLINE concrete protection liners allows the liner to bridge cracks in the substrate. Anchored thermoplastic sheets, the foundation product of ACROLINE Systems, are available in a variety of special designs including smooth, non-skid, dual wall, black and- white, fabric-faced, and embedded aluminum barrier in thicknesses ranging from 2 to 12mm. ACROLINE Systems are available in four types of thermoplastic including high-density polyethylene (HDPE), polypropylene random copolymer (PPR), polyvinylidene fluoride (PVDF), and ethylene and chlorotrifluoroethylene copolymer (ECTFE).
