How a suspended garage slab is built

Engineer’s design

Thickness, reinforcing and supports all come from the structural drawings. A suspended slab is never guessed.

Shoring

The slab is formed on shoring that stays in place until the concrete is strong enough to carry itself.

Reinforcing

Rebar laid out and tied to the drawings, and inspected before the pour where required.

The right mix

Garage slabs see road salt and freezing every winter, so the mix has to suit that. We confirm it when we price the job.

Suspended slab or slab on grade?

A slab on grade sits on compacted ground. A suspended slab spans over a space below, like a cold cellar, so it is a structural element: it needs an engineer’s design, shoring while it cures and more reinforcing.

Most new custom homes with a garage over a cold cellar need one. We pour it in sequence with your foundation walls, so it fits the same schedule.
