AKS™ CPL

CONCRETE CORROSION PROTECTION SOLUTIONS

Concrete has been used as a structural material for over 2000 years. However, the massive industrial progress made over the past 150 years has resulted in more aggressive environments, which have significantly reduced the lifespan of unprotected concrete structures. These demanding conditions created a need for more sophisticated corrosion protection solutions.

SUPERIOR SHEETING TECHNOLOGY

This moved the industry towards a new concept in concrete protection, cast-in concrete protection liners. AKS™ uses the robust qualities of High Density Polyethylene (HDPE) linings by enhancing the design through the creation of a close matrix of anchors. These anchors permanently secure the sheeting to the structure. This system has been designed to successfully and reliably adapt superior HDPE sheeting technology to an age-old construction material.

PERFORMANCE ENHANCING, COST REDUCING

AKS Lining Systems has taken the cast-in liner concept and perfected its design through the development of Anchor Knob Sheet (AKS™) technology, which surpasses all concrete protection alternatives on both costs saving and performance. Our AKS™ product is manufactured from HDPE and supplied in wide sheets or rolls to suit the project requirements.

UNIQUE ANCHOR LOCK

AKS™ is unique in its design, having 1230 anchors per m², ensuring that AKS™ is locked firmly into the concrete structure. Supplied in thickness from 1.65mm up to 10mm, it is used in a diverse range of chemically aggressive applications such as mining, water treatment and conveyance of sewerage. Once anchored firmly into the structure, AKS™ offers a chemically inert, flexible skin. AKS™ offers high abrasion resistance, is acid-proof and offers long-life expectancy in the harshest environments. Its superior crack bridging ability allows for movement in the concrete structure, without delamination.

Anchors are integrally formed with the sheet, enhancing the structure’s integrity whilst protecting the concrete from chemical attack.

TYPICAL APPLICATIONS

MINING AND BUND AREAS

AKS is used extensively in mining applications, where aggressive chemicals are contained or used. The flexibility of the AKS allows for easy installation over expansion joints and other challenging structures where more rigid coating systems fail.

WATER RESERVOIR

AKS, being produced from potable grade resins, is the ideal product for the long term water proofing of reservoirs. AKS can be fitted to new reservoirs or retrofitted to existing reservoirs.

EXTERNAL WATERPROOFING

AKS produced from HDPE or LLDPE resin is considered chemically inert. In high salt concentration groundwater, AKS offers the ideal long term external waterproofing option. Being a fully bonded application offers many additional benefits in terms of injection grouting or compartmentalizing of basement waterproofing.

WASTE WATER TREATMENT WORKS

AKS was specifically designed for the conveyance of sewerage and effluent. The use of AKS in WWTW offers a versatile, flexible, fully anchored lining system that can offer the longest possible design life for these structures. The added benefit of exceptional abrasion resistance offers further cost saving advantages.

AKS™ ANTISLIP

HDPE liners are renowned to be extremely slippery when wet. AKS Lining Systems offers the only tried and tested Anti Slip surface to our Cast-in liners. The anti slip surface texture height can be adjusted to accommodate both pedestrian traffic or vehicular traffic. This product is used extensively in bund areas or other areas where H&S of personnel is paramount. For more info click here.

DIGESTERS

The use of AKS on the underside of Digester soffits offers a number of benefits. The AKS, being fully anchored to the soffit through its 1230 anchors/ sqm, guarantees that the product remains firmly in place, while ensuring an acid resistance surface for the longest possible design life of these covered structures.

LARGE DIAMETER PRE-CAST SEWER PIPES

The use of HDPE AKS in conventional concrete pipes allows these pipes to be used in applications where previously only GRP, FRP or solid wall HDPE pipes would be considered. An AKS lined concrete pipe offers numerous benefits; Chemical resistance to nearly all aggressive environments, No limit to the size or diameter of the pipe, Smooth HDPE internal surface offers far higher friction values for additional carrying capacity, High abrasion resistance ensures minimal damage or wear and tear, Overall cost of Large diameter AKS lined pipe is greatly reduced compared to alternatives.

LINING FOR SEWER TUNNELS

AKS has been used extensively in the lining of TBM segments for large diameter sewer application. AKS, with its matrix of anchors and arrow shaped profile, offers the ideal anchor design to ensure the best possible bond to pre-cast elements. Utilizing Steel Fibre Reinforcing or conventional reinforcing, the anchor design ensures even distribution of concrete and firm anchoring of the liner.

AKS has an extensive track record in the internal lining of large diameter sewer tunnels. The prefabrication of large panels, in-situ concrete and grouting techniques have been well established. Having been used in the first such tunnel in 2001 in Singapore, AKS Lining Systems has extensive technical and practical experience in these specialized applications.

REHABILITATION OF EXISTING STRUCTURES

AKS, through its matrix of anchors, offers the ideal solution for post installation of an HDPE liner to existing, degraded structures. AKS can effortlessly be grouted onto existing concrete walls and floors, offering a long term solution to extend the service life of large containment and conveyance structures. The relined AKS structure will often offer the client a service life greater than the initial design of the concrete structure.

BUTTWELDING

WELDING ROD

AKS Lining Systems offers a pre-fabrication service in the form of “tube” production for the use in Vertical cast, pre-fabricated concrete pipes. This butt welding process minimises waste and speeds up the welding process for the liner requirements in these pre-cast element. AKS Lining Systems can either produce tubes from their in-house facility or assists clients in the establishments of their own butt welding facility though our trained engineers and extensive equipment supply network.

AKS Lining Systems offers a range of welding rod for the successful installation of our full product range. Produced from the same resins and masterbatch formulation, AKS Lining Systems can match the colour of the welding rod to the colour of AKS CPL Concrete Protection Liner or Geoliner Geomembrane. Welding rod is supplied in 5kg or 10kg reels and produced in 3mm, 4mm or 5mm diameter. For more info click here.
