Hollow-core was originally conceived and developed as South Africa’s alternative to insitu cast concrete floor panels for multi-storey buildings some 25 years ago. In today’s world of innovation and fast-tracking, the hollow-core floor slab is a viable and in many instances, preferable alternative to more conventional building methods. Besides the obvious advantages of simpler, faster construction, not to mention a more durable end product, the secret of applying the material successfully is in the pre-planning. Get one of the CMA member companies involved at the concept stage and their advice and design input comes at no charge. Set out in this manual are several examples demonstrating the versatility and multi-purpose functionality of the prestressed and reinforced hollow-core slabs. Applications covered include security walls, reservoir roofing, retaining walls and warehouse walling, multi-storey floor applications to residential, commercial and industrial buildings, as well as suspended ground floor slabs in clay areas. Also discussed are important sub-contracting aspects which apply when slabs are deployed in their more traditional guise as flooring.
