RAPFORM is composed of RAPFORM panels and injection moulded connector clips, which together provide stay-in-place concrete formwork for concrete walls, along with a permanent finish. The polymer panels are clipped together, and in combination the clips and panels allow for the construction of concrete walls. The concrete walls can be reinforced, as required by the engineering design, by easily installing steel reinforcement bars into the formwork system. RAPFORM provides customers with a complete solution including, walls, roofing, windows, doors and services. Once the system has been constructed the building is complete, and there is no further requirement for the post-construction installation of services.
