Precast concrete floors

ByKim S. Elliott

Precast concrete flooring offers an economic and versatile solution to ground and suspended floors in any type of building construction. Worldwide, approximately half of the floors used in commercial and domestic buildings, and more than three-fourths in car parks, are of precast concrete. Precast floors offer both design and cost advantages over traditional methods such as cast in situ concrete, steel–concrete composite and timber floors. There are a wide range of flooring types available to give the most economic solution for all loading and spans. The floors give maximum structural performance with minimum weight and may be used with or without structural toppings, non-structural finishes (such as tiles, granolithic screed) or with raised timber floors.
