Everything you need to know about shed foundations to help you build the best foundation for your shed


If you’re planning to build a shed, the first thing you’ll need to do is make sure that it has a solid foundation. You also want your shed to be able to handle the weather, as well as any weight that might come along with it. If you’re not sure how to build this type of foundation, don’t worry: I’m here to help! Here’s everything you need to know about how different shed foundations work and how they can help protect your new building project over time

Block piers

If you’re building a shed on uneven ground and want to ensure your shed is stable, block piers are a great option. A block pier is made of concrete, but instead of being poured into a trench in the ground, it sits above ground level. Block piers are not as strong as concrete piers or slabs (you can’t put much weight on them), but they’re cheaper and can be installed quickly—ideal if you need to get your project done fast.

Concrete piers

Concrete piers are an excellent choice for your shed foundation. They’re easy to build and can be built by anyone who knows how to use a shovel and level. Concrete pier foundations require no special tools, but you’ll need several bags of concrete mix, a few two-by-fours, some screws, and at least one steel pipe.

You’ll also want to make sure the ground is level before you lay down any foundation material or else it might not be supported properly later on when building your shed. You can do this with a spirit level or other piece of equipment that measures levelness (try searching “spirit level” or “leveling tool” in your search engine if you don’t have either). If there are spots where they’re unevenly sloped upwards/downwards then dig out some dirt from under them until they’re leveled out again – this will make sure that everything is flat enough before continuing on with laying down any concrete pier materials!

You should now have four pieces of wood placed around where the concrete footings will go; these will act as support beams so make sure these are sturdy enough for what we need them for later on when building our sheds!

Concrete slabs

If you want a shed with a large footprint and that will be used for storage or as a workshop, concrete slabs might be the best option. Concrete slabs are also an excellent choice if you have an uneven backyard or your property is on sloping ground. This type of foundation is ideal for sheds with large footprints because it provides plenty of support at the corners and along walls. Plus, the weight distribution makes these foundations more stable than other types of foundations.

A concrete slab should ideally be installed on level ground but can be raised up to 1/2 inch in places where access needs to be improved (for example at doorways) without compromising strength or stability too much.

To prepare for your slab, dig down into existing soil until you reach compacted subsoil; this will improve drainage around any pipes that may exist below ground level in case there’s ever flooding during heavy rains (which can happen even if it hasn’t rained recently). Then compact this layer by driving stakes into place and hammering them repeatedly with a sledgehammer until they are tightly compressed together so no air pockets remain between them–this step ensures that water doesn’t get trapped underneath when there’s heavy rainfalls!

Skids – floor beams fitted with footplates and anchored to the ground.

Skids are generally made of wood and are usually 2-3 inches thick. They can be as wide as 8 to 12 inches and between 8 to 12 feet long, depending on the type of shed you want to build. The width should be enough space for two people to stand on at once without touching each other when the skid is fitted with footplates (the wooden pieces attached to the bottom of a skid). Skids should also be spaced 4-6 inches apart from one another so that they don’t collapse under pressure if someone stands or walks on them too heavily.

Your shed needs a good foundation.

You need to know how much weight your shed will put on the foundation. This includes:

  • The weight of the shed itself.
  • The weight of the ground under it, which can be different depending on where you live and what kind of soil you have.
  • The total amount of pressure that will be put on your foundation by these two factors combined together (the earth is not lighter than air). Once you’ve added up all three numbers and calculated their sum in pounds per square foot—that is, how many pounds each square foot has to bear—you can determine whether or not a particular type of foundation is adequate for your needs.


Now you know all about the different types of foundations for sheds, so you can choose the best one for your needs. If you have any more questions, please leave them in the comments and we will get back to you as soon as possible!
