Concrete Slab Foundation

The perimeter of the concrete slab foundation should have a "footing" (12" wide x 12" thick) and in the center of the slab, the minimum thickness required is 4" inches. The 12"x12" footing is required to prevent the slab from chipping/cracking when anchoring the unit. Your local codes may require a larger footing, please consult local codes to determine your specific requirements. There are two options for concrete slab sizes.

  1. Edge Flush. The concrete slab size is required to be the exact size of your metal building. For example, if your unit is a 14' wide x 23' long then your slab has to be 14' wide x 23' long. With this option the base rail of the building will be flush with the outside edge of the slab. L-brackets welded to the inside of the base rail will be utilized for anchor placement. This will give enough distance from the edge of the slab to prevent chipping and cracking of the slab. Where building sides and/or ends are enclosed, side and end panels will extend beyond the base rail to prevent water from entering under the base rail.
  2. Edge Offset. The concrete slab size is required to be 6" longer and 6" wider than the size of your metal building. For example, if your unit is a 14' wide x 23' long then your slab has to be 14'6" wide x 23'6" long. With this option the base rail will be 6" from the edge of the slab and concrete anchors will be placed directly through the base rail. The 6" offset will give enough distance from the edge to prevent chipping and cracking of the slab. Where building sides and/or ends are enclosed, Z-flashing will be utilized to prevent water from entering under the base rail.

Concrete Strip Foundation

The perimeter of the concrete strip foundation should have a "footing" (12" wide x 12" thick). The 12"x12" footing is required to prevent the slab from chipping/cracking when anchoring the unit. Your local codes may require a larger footing, please consult local codes to determine your specific requirements. The footing is optional at open end walls and roll-up door openeings.
