Anchor Knob Sheet (AKS) is a “state of the art”, robust concrete protection liner system. The liner is manufactured from first grade Polyethylene resin (HDPE or LLDPE) and is designed to protect concrete structures in chemically aggressive environments.
AKS is a high quality liner, enhanced through the formation of anchors on one surface. These anchors are formed during the extrusion of the AKS sheeting and provide a total homogeneity between the anchor and the sheet, ensuring the highest possible adhesion to the structure and maximum reliability.
AKS is manufactured in a thickness range of from 1,65mm to 6,0mm and is suitable for a wide range of concrete protection applications.
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.
