Storage Shed Foundations
Every project big or small starts with a good foundation. The storage shed foundations are the building block for the whole structure and should be carefully analyzed in the planning stages, to make sure that it is stable and completed correctly. This is your investment that you have put money and energy into. You want it to last you for the long term. The foundation will determine the success or failure of the structure over time.
Learn Which Foundation Is Right For Your Project
A proper set of plans normally outline options for different storage shed foundations but it is best to check with your City Permit and Planning Department to ensure that you are building to the codes and guidelines regulated.
There are several key factors that determine the best storage shed foundations. These include the size of the shed, climate zone you live in and the shed floor type you are seeking.
There are basically 2 categories that storage shed foundations fall into. These consist of on-grade and frost proof foundations. On grade which is often referred to as a floating foundation will sit right on the ground and is stable for many small structures. Many people prefer this option because it does not require any deep digging or concrete footings.
It is important to point out that the shed foundation is the base in which your shed will be mounted upon. Of course the least expensive and easiest to create is a dirt floor which would only be suitable for something like a pole type barn, but if your shed is constructed with wall enclosures then it will need to be stabilized with a dry level surface in order to support the frame properly. This can be achieved with solid concrete blocks laid on the surface.
A frost proof foundation is definitely more supportive, providing a strong and long lasting base. They are designed to be resilient against ground movement in cold-weather regions. This can be achieved with a concrete pier or slab but is an expensive alternative. You would need to have a comfort level with pouring your own concrete slab which takes a bit of skill. You must take steps to protect the slab from cracking which is caused by ground subsidence and humidity. Concrete slabs also absorb water so pressure treated wood is necessary where contact is made with the concrete. Concrete piers are poured below the frost line and attach to beams to support the shed. This provides a good solution for solid support and keeps the structure off the ground. You must make sure that the footings are placed on undisturbed soil or 4 to 6 inches of crushed gravel.
No matter what option you decide to go with, the most important thing is that your shed will rest on a level surface in order for the doors and windows to function properly. The water must also run away from the foundation to avoid the structure from potentially sloping.
