There are only 2 main ways to construct a suspended slab – conventional cast-in-situ and the rib and block slab system.
With a conventional slab, all the components are assembled on-site and the entire slab has to be shuttered and all of the concrete poured on site. The advantage is that large spans unsupported can then be achieved with cast-in-situ slabs but are usually much more expensive than alternative systems.
Rib and block slab systems have the lintels and blocks precast and delivered to site. This system uses less concrete and is quicker and cheaper than conventional slabs.
SupaSlab was established in 2000 by its founder Alec Marot who had been experimenting and fine tuning the system for many years. He has since become a leading authority on the system and he is often consulted by leading engineers to problem solve difficult situations where his extensive experience provides expert solutions.
