Coffrargile disposable formwork

8 sp p h L Advantages: • Ease of positioning due to die cutting. • Easy to cut to permit the passage of ventilation pipes, sewer and system piping. • Quick to install, saving up to 80% of the time required for traditional procedures. L-Plast accessory L-Plast is used for new constructions to create the slab and foundation beams with a single concrete casting; when restructuring is used to easily create reinforcement curbs for existing foundations. Furthermore, L-Plast is ideal for creating air ducts in general, such as for cold rooms, for example (if forced ventilation is necessary) or in geothermal applications where air must be blown into the under-fl oor cavity. When restructuring, when the existing walls must be reinforced or when an underpinning must be created, L-Plast is a useful work tool that helps creating a new slab or reinforcement base with a single casting. Case study: new construction on swelling clays As part of a major operation on the outskirts of Paris, we were faced with the challenge of constructing a residential complex on a plot composed of swelling clays, a situation that would surely compromise the foundations. This situation is normally resolved by constructing the foundation on posts with a distribution mat “suspended” on their heads, a very laborious and expensive solution. By using Coffrargile, in combination with its accessory Beton Up, we were able to create a simple scaffolding on which it was possible to install a 50 cm thick, load-bearing, reinforced concrete slab, with an underlying cavity, the purpose of which was to accommodate the swelling and shrinkage of the foundation sediments. The use of Coffragile with its accessory Beton Up enabled the creation of a pedestrian- accessible platform capable of bearing the 50 cm thick reinforced concrete in the design specifi cations. Thanks to Coffrargile, which is solid and suitable for any and all weather conditions, the construction company was able to complete the work more quickly and economically than would have been possible with traditional solutions. For the sections in which the 50 cm x 50 cm modules did not fi t, the Coffrargile elements could easily be cut and adapted to any shape. This project highlights Coffrargile as an innovative and economical technical solution for treating the problem of swelling clays.
