The Best And Worst Concrete Base Foundations For A Steel Shed
By Nick Polishchuk
The simplest way to make a concrete base for your steel shed is clear the topsoil, excavate to a depth of over a foot, add a layer of sand, and then pour concrete.
You'll need to smooth the entire surface of the wet slab, then create grooves in it to act as control joints. A more complex option is to build a frost-proof concrete foundation.
If you live in a region where the soil freezes over in wintertime, this type of foundation requires you to excavate deeper and pour concrete footings and piers to prevent cracking.
Laying down concrete pavers gives you the benefits of a stable surface, but without the hassle of putting up formwork or pouring concrete.
