FOUNDATION NOTES

 You should check with your local building official or Code Enforcement Office for the foundation

requirements in your County. You will need to know the frost depth, the wind load and the snow load to

determine the size and depth of the footings.

 If you order an engineering drawing package it will include a foundation drawing. The typical VersaTube

foundation is a 4” thick slab with 12” wide x 12” below grade footing. The footing has two runs of #4 rebar

running the length of the footing, one 3” from the bottom and one 5” above that rebar. The rebar is

centered in the footing. We also recommend a welded wire fabric reinforcement 6/6/10/10 at mid-depth in

the slab. You could also use #3 rebar in a square grid pattern 24” on center.

 The ground should be compacted to a minimum of 1000 PSI bearing pressure.

 If you have a frost depth deeper than 12” you will need to extend the footing depth down to or below the

frost line.

 We recommend the use of a 1 1/2” x 1 1/2” sheeting ledge around the top edge of the slab. This will close

off the bottom of the side metal panels and prevent water from running onto the building floor.

 If you do not require a concrete slab, you can pour concrete strip footings without a slab.

PIERS: You can use concrete piers in place of the slab and footing or strip footing. The piers must be sized to

support the dead load of the building plus the roof snow load. The piers must be deep enough to resist the

wind uplift on the building and be at least as deep as the frost line. Our typical pier is 12” in diameter. Larger

buildings and buildings with a heavy snow load will require a wider pier. Piers are typically located at every

post.

CONCRETE: We typically speck 2500 psi concrete, however some Counties require a denser concrete.

Please check with the building department for a recommendation. If your building in located in a high wind

area you may need to increase the concrete density to get better pull out ratings on you anchors.

ANCHORS: We recommend concrete wedge anchors be used to anchor your VersaTube building. On the

sides of the building we use 5/8” x 5” anchors with the base plates and 5/8” x 7” anchors with base rails.

On the end walls we use 1/2” x 4 1/2” anchors for base plates and 1/2” x 7” anchors for base rails.
