Guidance on a range of different floor types: post-tensioned slabs, flat slabs, ribbed & waffle slabs, hollowcore, water and air cooled slabs as well as information on floor screeds.
Flat slabs are highly versatile elements widely used in construction, providing minimum depth, fast construction and allowing flexible column grids.
A floor screed is usually a cementitious material applied onto either a solid in-situ concrete ground floor slab or onto a precast concrete floor unit. There are many proprietary screeds on the market and information about these can be obtained from the manufacturer.
Hollowcore slabs derive their name from the voids or cores which run through the units. The cores can function as service ducts and significantly reduce the self-weight of the slabs, maximising structural efficiency.
Post-tensioned (PT) slabs offer the thinnest slab type and long spans can also be achieved. PT slabs use high-strength tensioned steel strands to compress the slabs, keeping the majority of the concrete in compression.
Ribbed and waffle slabs provide a lighter and stiffer slab than an equivalent flat slab, reducing the amount of concrete needed.
TermoDeck is a system that uses the thermal mass in hollowcore concrete floors to provide low energy heating and cooling.
