Our metal garages can either be anchored on concrete or the ground. The vast majority of people install theirs on concrete but sometimes, a purchaser elects to have a gravel surface on the inside of the building in order to save the cost of pouring a concrete floor. This works fine if the garage is solely for storing RVs and such but not much good if you intend to “mechanic” or use the building for a workshop.
Metal Garages Anchored On Concrete:
Concrete Installation using Expansion Anchors:
We supply you with the proper number of 7” x ½” concrete expansion anchors or “RedHeads”. If you happen to lose one, you can get these at most any hardware store. Installation is by drilling the concrete where the pre-drilled hole in the base rails are and then inserting the expansion anchor, tapping it down all the way if necessary with a hammer, then placing the washer and threading on the nut (supplied with the anchor) and tightening it down.

Ground Installation using Concrete Caisson:
On larger units we recommend anchoring the base rails with a concrete caisson under each pre-drilled base rail hole. We make a hole 30” deep by about 8” in diameter. Then lay the base rails down, insert the 30” ground anchor and fill with posthole concrete.
