Do I Need a Base for my Garden Shed?

What is a shed base?

A base is essentially a garden shed foundation. However you plan to use your shed, there are different types of shed base options which all serve the same purpose: to provide a solid foundation on which to stand your new garden shed.

Is a shed foundation necessary?

This is a common question. In short, the answer to this question is yes. There are several reasons why a shed base is essential.

The first is that no matter how level you think your garden is, you cannot get a shed to sit flat without a support underneath. If your garden is sloping or on uneven ground, the shed base provides extra support. If you build your shed directly on to the ground or grass, the weight of it would likely make it sink.

Another important reason for having a garden shed foundation is to prevent your shed from getting damp. If you place your shed directly on to the ground, then moisture may make it damp and cause problems with rot. This can lead to the shed becoming weak and deteriorating long before its expected lifespan.

The best base for a shed

Another question we are often asked is, “what is the best base for a shed?” There are lots of shed base ideas and we’ll go through the most popular options here:

Concrete

Concrete slabs or concrete shed foundation blocks are often used as a shed foundation. They are good for supporting larger, heavier sheds, or sheds which will be used for heavy duty equipment such as a workshop shed. Concrete shed foundations require low maintenance, but it’s essential that a concrete base is laid completely flat and is level in order to support your new shed.

Wood

 When it comes to choosing the best base for a shed, another contender is wood. This usually takes the form of a wooden frame which acts as a shed platform and is anchored into the soil using either spikes or concrete levelling blocks in each corner to give stability. The good thing about a wood frame is that it allows air to flow under the shed, which helps to prevent damp. This is an inexpensive option, especially if you wish to make the shed base frame yourself.

Plastic

A plastic base usually comes in sections which you fix together and fill with gravel to provide strength as well as drainage.

How to decide on the best base for a shed?

There is no right or wrong choice when it comes to shed foundation blocks. The only thing we would emphasise is that you do need some form of base before installing your new shed.

When trying to work out the best shed base for your needs, we suggest you think about the type of shed you’re going for. How big is it and what is it made of? A heavy duty workshop shed will, for example, need a more durable base than a small bike shed. Think also about the location of your shed and the type of ground it will be sitting on.
