Shed Bases on Uneven Ground – How to Level Up?

All sheds need to be built on a flat, level base otherwise you risk damaging your shed, reducing its lifespan or, even worse, having your new shed fall over. But what happens if your garden has a slope, or your ground is uneven? Here we look at how to build a shed base on uneven ground.

Planning a location for a shed on a slope

Before you start building a shed base on uneven ground, you’ll need to spend some time planning the location of your shed.  Consider what you’ll be using your shed for, and the distance from your house.

Think also about the digging conditions. You’ll want to avoid digging through hard, rocky soil or tree roots, so try to choose your location wisely.

How to build shed bases on uneven ground

If your garden has only a slight slope, the easiest way to make a shed base level is to remove and relay soil. If the gradient is bigger or moving soil isn’t possible, then the easiest way to build a shed on uneven ground is with a concrete block shed base.

Concrete foundation blocks are less expensive than concrete mix and can be used flexibly. They are an easy and effective way to work in levelling ground for a shed.

If you’re looking at how to make a shed base on uneven concrete, you’ll need to use planks and a spirit level and screed the area first.

Mark out the area for your shed and remove topsoil

Mark out the area of your shed with wooden pegs and string. Next, using a garden spade or shovel, you’ll need to remove the grass, topsoil and rocks to a depth of about 13cm.

Level the ground

If you’re wondering how to level a shed on uneven ground, then this next point is key! We recommend using wooden planks to lie across the stripped ground to highlight uneven areas. You can use your spade to distribute soil from the higher ground to the areas which are on lower levels. At this point, you can use your concrete blocks to help even out the base.

Use a weed membrane

The next stage in building a shed base on uneven ground is to install a weed membrane. This will stop weeds growing through the base of your shed and causing damage for many years to come. Finish off by using a spirit level to ensure your surface is flat before you move on to the next stage.

Choose the material for your shed base

Now that the ground is prepared, you can think about how to build a shed base. There are lots of shed base materials to choose from including wood or concrete.

Think about how you’ll be using your shed and how much support is needed in the base. For example, a shed being used as a heavy duty work shop with work benches and lots of tools will need to be supported with a sturdy base like concrete rather than a shed that is being used to store light weight bikes.

Finally, you can now construct your shed base before the installation of your new shed.
