A Suspended Garage Slab Creates Extra Space Below
 |
The garage walls are poured in normal fashion with a slab below for future use.
|
|
A grid work of steel beams is installed. To support a concrete slab over deck.
|
 |
 |
Metal deck is installed and fastened to the Beams. #4 rebar is installed at 12" on center each way to reinforce a 5" slab
|
|
Finally, 5"of 3500 psi concrete Is poured over the metal deck. Slope can be back to front or to a center drain.

General Description:
The floor is constructed using a platform of high strength wide flange beams spaced at 5’ 0” on center running perpendicular to and either flush with or continuous over the main beams depending on available space.
This platform is covered by 1.5 C 20 gauge metal deck with a 3” x 4”x 1/4” steel angle mounted around the entire perimeter of the basement to serve as a deck support. Regular weight concrete is poured over the metal deck to a depth of 4” and reinforced with #4 rebar at 16” on center each way. There are no wood elements in the system susceptible to organic growth.
With appropriate waterproofing measures and sufficient vertical room, the space below can be improved for a number of purposes
Materials:
Main Beams: 10” or 8” beams as sized by the engineer running North-South resting in wall mounted angle iron beam saddles and supported mid span by a 3” diameter schedule 40 mono post anchored to the top of the concrete caisson or pad and welded to the bottom of the beam.
Purlins: 8” beams as sized by the engineer running East-West at 5’0” on center welded to the main beam and supported at the side wall with angle iron beam saddles.
Decking & Concrete: 1.5 C 20 painted metal deck as manufactured by Vulcraft or equal. 4” concrete slab with #4 rebar at 16” on center each way at mid depth. Design Criteria: Dead Load 58#/sf, Live Load 50#/sf (2000# Point Loads) Deflection: Negligible Void Space Access: Through blockout in foundation wall by general contractor (if desired)
