About Our Shed Foundations in NJ

Our gravel (crushed stone) shed bases are our most popular form of shed site prep in New Jersey. A gravel shed foundation is the best for prefab sheds and other buildings with pre-built wooden floors. We use compacted “clean” stone, which provides a firm base for your shed while still allowing water to drain through.

Up front and honest.

Our site was challenging. Lots of buried boulders and a bit of a slope. They worked with us to decide exact placement of the shed foundation, and saved us money buy moving it to an area with a little less slope. They were up front and honest with us about some of the site challenges,
