At Absolutely Amish Structures we know a great, long lasting shed or garage starts with a solid foundation.  Depending on the size or use of your new building will determine the type of foundation you can use.  There are some where a gravel foundation will work but with others a concrete slab should be poured.  Let our friends with Site Prep LLC help you with this so that your delivery and installation of your new building goes smoothly.  For more information check out their website.
