Strong as an Elephant
Elephant Structures is proud to offer both standardized buildings, and fully custom carports, garages and commercial buildings. We can meet any need, anywhere, and you’re sure to receive a quality building. This garage can be installed on almost any level surface, from raw dirt, to gravel, asphalt, concrete, and even wood decking. The construction foundation must be level, within 3” in any direction for the building to be installed. We do recommend a concrete foundation as this provides the most quality construction quality and long-term performance of the structure, a level building site will ensure weather protection and proper alignment of the galvanized steel legs, metal sheeting, and roofing panels so it will looks as great as it performs. Concrete footers may also be used in place of a full concrete pad – engineered foundation drawings will be provided with your purchase to designate how the foundation should be prepared if you’re pouring concrete or using footers.
