DISPOSABLE FORMWORK FOR COUNTERACTING THE DEFORMATION OF ARGILLACEOUS FOUNDATION SEDIMENTS With foundation problems in clayey soils, conditions which facilitate a “proactive” approach with regard the soil rarely occur within the scope of the project. In most cases, the structure is designed and its behavior is then anticipated as a function of the mechanical characteristics of the soil, while only seldom is it possible to act on these in order to modify unfavorable environmental conditions. Daliform Group created Coffrargile, a disposable formwork made of recycled plastic, to effectively handle the movements of clayey soils and protect floors from shrinkage/swelling. Coffrargile is used in combination with Beton Up, an accessory that prevents the reinforced concrete from forming the “pillars” typical of the classic Iglu’® system. In this way, the formworks take on the function of simple scaffolding on which a load-bearing slab of reinforced concrete can be installed with a cavity below, the purpose of which is to accommodate the swelling and shrinkage of the sediment underlying the foundation due to the special mechanical properties of clayey soils. APPLICATIONS Coffrargile is the effective solution for creating cast-in-place reinforced concrete slabs that do not suffer from the effects of swelling and shrinkage inherent in clayey soils for the construction of office and commercial buildings as well as civil and industrial projects which are threatened by underlying clayey sediments.
