How Firm A Foundation
Customers always want the best foundation for their storm shelter and many assume they need to pour a concrete pad. While that is necessary for most above ground storm shelters, it really is an unnecessary expense for a Safe Shed tornado shelter.
Our shelters have a 6" steel reinforced floor that is seamlessly connected to the 4" steel reinforced walls. Most other shelters don't have a floor at all and require the buyer to pour a concrete pad, reinforced with a rebar grid, that they can attach the storm shelter to for anchoring. And the thickness, reinforcement, and quality of the concrete pad the customer pours determines how safe the shelter will be, ultimately. Plus the cost of pouring a suitable pad for the floorless shelter is in addition to the cost of the shelter you're buying. It can really start to add up!
So what's the best foundation for a Safe Shed storm shelter? We prefer that you set our concrete tornado shelters directly on the ground, with just a 3" to 4" thick layer of level gravel. The weight of the shelter will cause it to settle nicely into the gravel pad, and our installers can easily auger down 4' below the shelter at all four corners to anchor it securely to the ground.
Save yourself some time, money, and stress...forgo the concrete pad and choose a Safe Shed above ground storm shelter so the floor, walls, and roof all form one seamless building.
