How To Level A Shed On Concrete

Read this article to learn how to level a shed on concrete.

How’s your slab?

So, you’ve acquired council approval. If you’re going to pour your slab yourself, you’ll save a lot of money, but beware, your investment may end up being a huge mistake - a mistake forever cast in stone.

You should have:

  • permit requirements
  • foundation
  • location
  • shed type and size
  • the shed manufacturer’s instructions for shed erection

It is imperative to build your shed on a solid, well-drained site so that cracks don't end up developing in your slab.

It may be far more cost effective to have an excavator remove the dirt if your shed is large and there is much earth to remove.

Your Site Must Be Firm And Level

Without proper preparation, your shed will be improperly assembled and erected. The screw holes won’t line up and your anchor bolts will not be driven home as securely as they need to be. Aside from that, you can imagine improperly fitted doors - a disaster!

Ensure that when the shed is being assembled, you have access from all sides. That means
you need to set your base far enough away from walls and fences. And if you have intentions of having electricity installed, consult an electrician before selecting your site.

If you need precise wood cuts as part of your shed construction, I would suggest having a look at some of the woodworking articles on Carve Your Creation.

Now that your site is level, your forms should be strong and able to support the concrete until it has cured. Like a cake that is frosted, the frosting needs time to set. It’s now time to place
your shed on top.

Concrete Base On a Slope

If your concrete slab is on a gradient, consider foundation blocks or a retaining wall: two methods that have been proven to be most successful.

Foundation Blocks

Foundation blocks are a good way to level your shed, and you can add or remove blocks as required.

You’ll need:

  • masonry blocks
  • shovel or post hole digger
  • treated timber lengths
  • gravel
  • measuring tape
  • string line
  • spirit level

You’ll be digging holes two inches wider than your blocks and you’ll be heading six inches deep to sink them.

Use the gravel to keep the blocks aligned and place a length of timber on which you’ll place your spirit level (1) to ensure the ground and the blocks are all even.

Retaining Wall

A retaining wall (2) is another option, but you can expect it to cost significantly more.

You’ll need to consider the balance of the cut in the earth and the compaction. You'll also need plenty of space to work.

Reminder: Check with your local authorities before you begin any work to level a shed on concrete.
