Piers are the most common and cost effective type of floor support and can be:
- brick piers
- timber stumps on galvanised "shoes"
- steel posts that are bolted in each corner onto the pad footing with a "Dynabolt"
- precast reinforced concrete
- core filled concrete block work
The bearers rest on top of the piers and usually run the direction of the longest wall. Joists are then laid in the opposite direction. Floor boards or sheet flooring is then laid on top of the joists.
