Raised floor systems, also known as access floors, are an elevated structural floor that is stabilized over a solid substrate, typically a concrete slab. A raised floor system creates a gap ideal for running electrical wiring and HVAC ducts. The structural floor is composed of panels on a grid supported by adjustable vertical pedestals. The pedestals are affixed to the subfloor through either mechanical fixings or adhesives. Since the pedestals are adjustable, the gap between the elevated floor and the subfloor can be between 3 and 48 inches.
