Stone Base and Gravel Driveway College Grove, TN The gravel driveway is a cost effective option that provides easy access to the home and new shed. The shed pad is complete and ready to last for years to come! After the framing is complete, stone is poured as one of the final steps of the project. Stone is also added to the driveway after excavation is finished. The area for the shed pad is excavated to establish a level site before the framing begins. Before construction begins, the site is framed for the shed and the size of the gravel driveway is confirmed.
