What kind of foundation should I opt for my metal building?

The right foundation depends on your building type and ground conditions. For enclosed buildings (garages, workshops): You’ll want a full concrete slab. It needs to be reinforced with steel and have thicker edges to support the building. A professional concrete contractor should handle this using the exact plans we provide. For open structures (carports, RV covers): Concrete piers work best and cost less. These are tubes of concrete set deep in the ground below the frost line. Your building’s posts anchor directly into these piers. The center area can stay as dirt, gravel, or be paved later if you want. For big farm or storage buildings: Some larger buildings use a perimeter foundation with a short wall (called a stem wall). This provides a solid base around the edges while the interior can be gravel or a thinner concrete floor. Important : We give you detailed plans showing exactly where to place the anchor bolts for your specific building. Don’t pour any concrete until you have these plans – they’re different for every building we make. Your concrete crew needs to follow these plans exactly so your building will bolt down properly.
