Concrete Slabs for Garages and Workshops

Vehicles, lifts, tool storage, and heavy equipment all affect what the slab needs to handle. Real loads drive real specifications.

Thickness for a workshop or garage floor is typically greater than a residential patio or shed pad. Exact numbers depend on use and site conditions.

Rebar or heavier wire mesh is often part of the plan for these slabs. The right choice depends on the specifications for the project.

Slabs used for wet work — washing vehicles, spilling coolants — benefit from planned slope and, sometimes, floor drains. Drainage should be planned before the pour, not after.

A smoother finish is common for garage floors because it's easier to clean. Traction near doors is worth considering, especially in areas that see rain.

Trench lines, electrical stub-ups, or air lines that need to run through or under the slab should be planned before pouring.
