Concrete garages are constructed with precast concrete or cast-in-place concrete. The major difference between the two methods is that the precast concrete has pre-tensioned, prestressed strands within, and the on-site poured cast concrete requires post-tensioned, prestressed strands or rebar within.
For some projects, it may not be possible to do the post-tension stretching at the site safely. A garage that is positioned tightly between other structures or is located underground would require precast, pre-tensioned, prestressed concrete.
A lack of sufficient parking can cause congestion and unsafe conditions. Stakeholders of such projects are usually eager to resolve the situation. The affordability of precast concrete and the speed at which it can be produced allow these projects to be finished quickly.
