I'm designing a residential garage with basement underneath. The foundation will be conventional concrete. However the floor to support the vehicles is a design / engineering problem.
Is it less expensive overall to use:
A) prestressed concrete slabs (such as hollow core or perhaps double T)
or B) stage and form and then pour concrete reinforced with rebar?
This is for a modest residential two-car garage attached (tied-in) to the home's existing foundation. probably 22x22 or 24x24 feet.
We have many freeze-thaw cycles per year. I don't think we want a wood floor, unless you have a good reason.
I would like to hear from anyone with experience using the prestressed/prefab concrete products. Also was it easy to find an engineer to sign off on the plans.
Please also send in any useful links, thanks.
