For a level, well-draining site, patio stones can be placed on top of your grass under the wood floor pressure treated runners. We typically use between 6-9, depending on the shed size. The patio stones are included in our installation service when you order a wood floor.
For areas with poor drainage, we recommend removing 6-8 inches of topsoil and replacing it with a crushed gravel base to allow the water to flow. The patio stones can then be placed on top of the gravel.
Cement pads are typically the best foundation for all sheds. The pad has to be a minimum 4″ thick and sit approximately 2″ above the grass line. It should be edges, not curved, and flat, with no drainage slope. To hide the cement pad, make it the same size as the shed floor. In cases where there is a large grade, cement footings are a better option.
