Flexicore

Flexicore is a type of precast, prestressed concrete floor slab. It is often used in construction of multi-story buildings. The advantages it has over a poured concrete floor are that it is lighter in weight and often cheaper. Also, wet concrete does not need to be pumped or carried up to higher floors. The slabs which are manufactured off site are simply lifted with a crane and set in place.
