HOLLOW-CORE SLAB SYSTEMS

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.
