The use of precast flooring components in the building industry is an economical alternative to the traditional practice of formwork and insitu concrete. With flooring typically 6-8% of a structure's total cost, savings of up to 30% of a project's construction time make precast flooring a logical decision when selecting the type of flooring.

Types of precast flooring
It is recommended that you contact the precast manufacturer of your choice in the early planning stages to determine the most appropriate flooring system and availability.
