1 PERMANENT FORMWORK SYSTEMS For In-situ Ground Beams & Pile Caps GROUNDFORM CELLFORM PILE CAPS

A Growing trend Traditional shuttering techniques for forming in-situ ground beams are increasingly being replaced, by quicker and less labour intensive alternatives.

2 A Growing trend Traditional shuttering techniques for forming in-situ ground beams are increasingly being replaced, by quicker and less labour intensive alternatives. A trend that is encouraged by the emphasis on fast track build programmes and a shortage of skilled tradesmen Now Cordek supplies the labour Reacting to this trend, Cordek have developed a complete design and supply service for an extensive range of permanent formwork systems. Off-site Fabrication Cost Savings Speed Less Labour Groundform Cellform Pile Caps Manufactured from heavy duty Correx polypropylene board to help maintain cover to the re-inforcement, they all reflect Cordek s commitment to quality. Quick and simple to install Minimise the need for skilled labour Supplied on short lead times Components are tailored to site requirements Speed construction and save money The Cordek range of permanent formwork systems bring added value in a number of other ways however.this brochure goes on to explain and illustrate the unique features and benefits that have been designed in, to meet the Contractor s requirements.

3 When forming in-situ reinforced concrete beams it is usually the ground conditions that determine whether formwork is required. Pile caps however, nearly always require formwork. The Cordek Systems Cordek s Groundform System is a practical cost effective solution for forming in-situ beams and pile caps. While the Cellform System offers the same benefits as Groundform, uniquely it also provides built in protection against ground movement or clay heave. Pile Cap Cost effective support Full take-offs are provided from general arrangement drawings, like the one below.the final system is assembled from multiples of the standard units, which are supplied to site together with an allowance for wastage. Quality matters The Cordek systems are manufactured from an extra rigid grade of Correx polypropylene board.the grade selected is the result of extensive site tests, and offers the best value. Lower rigidity boards were also tested.while they offer cost savings which may be superficially attractive, the levels of deflection that occured were considered unacceptable. Groundform Cellform 1

4 Groundform System design, installation and support Groundform is Cordek s permanent formwork system for constructing in-situ ground beams and pile caps on both residential and commercial projects. Generally supplied as a complete U profile, it removes the need for concrete blinding and minimises dig requirements. Corner Connector Formbrace Infill Panel Straight Connector Re-usable formwork systems require working space for fixing and striking.this invariably results in additional double handling and stockpiling of soil. The U shaped beam profile is cut and creased to site requirements in standard units, on Cordek s dedicated production lines. A variety of high rigidity board sizes are used to minimise wastage. Our standard units generally include an extra 25mm on each side, to allow for site tolerances. Sides only formwork solutions are sometimes preferred.this may be appropriate when complex reinforcement cages require in-situ fabrication. While large sheets of Correx board are used in the manufacturing process, they are very difficult to handle and cut on site.apart from the obvious health and safety risk, there is an environmental issue in respect of waste and Cordek do not supply formwork in this format. 2

8 Cellform Product design and application Cellform is a unique permanent formwork system for the construction of in-situ concrete ground beams and pile caps, in areas where ground movement is predicted. Cellform has been patented by Cordek Corner Connector Formbrace Double Infill Panel Straight Connector Claymaster Single Infill Panel Claymaster Pile Collar Cellcore Patent No Suitable for residential, commercial and industrial projects, Cellform is tailor made to specific site requirements based on general arrangement drawings and the predicted ground movement data supplied. From such drawings, Cordek s technical department will provide a full scheme detailing all necessary components, the optimum grade and depth of Cellform to be used and the Claymaster requirements, including pile collars. Manufactured from expanded polystyrene and heavy duty polypropylene, it incorporates the proven Cellcore technology for protection against upward movement. Claymaster is used to protect against lateral movement. 6

10 Accessories/Components & Installation Cordek have developed a full range of components for their formwork systems, to ensure easy installation and foundation integrity. Cordek s unique connectors provide a grout tight finish to minimise concrete wastage and safeguard beam integrity. Cordek recommend the use of Tric- Trac spacers to ensure the correct cover to the reinforcement. Formbraces are used to maintain the formwork profile during the installation process. On sites where clay heave or ground movement is anticipated, the use of Claymaster is recommended to accommodate the horizontal ground movement that will occur. Cordek provide a tailor made cutting service for Claymaster, including special shapes like the circular sections for pile collars. 8
