Tips for Building a Gravel Base for Your Shed
Just like a house, a garden shed needs a good foundation. Fortunately, a shed is much smaller, so you don’t need a foundation that is as large and you have more options for building a base for your shed. Try Gravel Base for your Shed.
When it comes to garden sheds, building a gravel base is one of the most common recommendations. In this post, we are going to look at some tips for planning and building the base for your storage shed.
How big should the base be?
The first thing you need to plan is the size of the shed’s foundation. A good recommendation is to build the base about a foot wider and a foot longer than the shed. This will give you about 6” of clearance on each side. The reason to build the base a little bigger is to assist with drainage and to prevent mud and dirt from splashing up on the sides of the structure. It will also make it easier to maintain your landscaping around the shed.
You also have the options for the depth of the base. Most shed builders would recommend a 4” or a 6” pad. Once you have the space cleared out and leveled, you can then frame the area of the base with pressure-treated lumber. Depending on the depth of the pad, you can go with 4”x4”, 4”x6” or 6”x6”.
Is concrete a better option?
Gravel is the best option for most storage shed foundations. Concrete would only be necessary if you are building a shed that is particularly heavy or if you plan to store heavy items like a car. The first thing to point out about choosing concrete for your shed foundation is that it is going to cost more and it is going to require more work. However, that is not the only reason why gravel is a better base material for most sheds. With a concrete shed foundation, water will just rest up against the edge of the base. If you go with gravel, you get better drainage and this will protect the shed from water damage.
If you are planning to build a garage or a large storage shed, then concrete might be the better option. As an alternative, you could consider building a gravel base with concrete piers for added stability.
Which type of stone should I use?
The best type of stone is going to depend on the location. Most shed builders would probably recommend ¾” stone for a shed base. It is small enough to pack together well and it can provide good drainage if the shed is in a wet area. Another option is to go with crusher run stone. Crusher run stone packs together really well and it will provide a firm foundation. The only issue is that if the area has a tendency to hold water, it could compromise the base of your shed.
What if the shed is not level?
Many homeowners do not realize the importance of accurate leveling when they put a shed up. The truth is, your shed needs a stable foundation that is level. This allows the weight of the structure to be evenly distributed and it will help you to avoid a number of problems.
