Reinforced concrete precast double wall BASEMENTS

Advantages of Basements More living space Enhanced property values Better utilisation of building land Improved use of sites with difficult land Construction Method CCP offer precast basement units using the double wall construction method. Double walls are essentially a precast/insitu concrete hybrid which offers all of the advantages of precast concrete with the robustness that insitu concrete affords under the ground. A double wall is a precast concrete unit comprises of two concrete leaves; typically 65mm thick connected with steel lattice girders. The unit is relatively light as there is a cavity between the units which is filled with insitu concrete. When the unit is installed on site, it is temporarily propped and connecting steel to other adjacent double walls or half floor units is placed in the cavity prior to concreting. Once the concrete has hardened a single monolithic element is created. The process is fast and avoids expensive on site formwork as the leaves act as permanent formwork. The units have an outstanding high quality factory surface finish which can be very difficult to achieve on site.
