AKS Lining Systems is a specialist manufacturer of high performance Concrete Protection Liner (CPL) materials. The cast-in liner, called Anchor Knob Sheet (AKS) is attached to concrete structures through the embedment of its 1230 anchor knobs/studs per m² into the concrete. The optimal size, shape and number of knobs ensures an extremely high pull-off resistance from the concrete. The anchors are homogeneously formed with the HDPE liner during the extrusion manufacturing process. The high chemical resistance of HDPE, along with proven welding and testing systems, ensure that sewers, manholes, pump stations and other concrete structures, which operate in chemically aggressive environments, are provided with long-term protection against corrosion. Additional benefits, like raised carrying capacity, through a low friction coefficient, when used for liquid conveyance, make this a cost-effective solution for a wide variety of lining applications.
