How to build a shed base with paving slabs

Do I really need a shed base?

Yes. Most definitely. Without a doubt.

Placing a shed directly on grass will lead to rot, structural instability and a shorter life for your shed. Skipping this vital step will only lead to problems later on. And they'll probably be sooner rather than later.

You do have options when it comes to laying your shed base. One of the most common ways to construct a shed base is to use paving slabs. You can also opt for a plastic grid system shed base, a wooden shed base or a concrete shed base.

 

A Paving Slab Shed Base

The first thing you will want to do is to clear any vegetation from the area that your shed will reside. Remove the rocks and stones as well as bits of plants and roots, anything that may cause uplift. This will make it easier for the slabs to be placed.

Peg out the size of your shed using string and pegs, giving 20cm extra and start shoveling out the top layer of soil, digging down around 2.5inchs (6cm) deep. This will provide enough depth in order to create a flat surface ready for slabs to be placed.

A mixture of sand and cement (1 part cement to 8 parts of sand) is then placed inside the dug out square. Using a rake, you can evenly distribute the sand to the point visually it looks level. Use a spirit level to get the layer as even as possible.

Place your paving slabs, starting from one corner and use a rubber mallet to hammer down the slab to get it as even as possible. Using the spirit level, you can work out and get the slab perfectly flat, adding more sand if needed underneath the slab until its perfect.

The slabs need to be just above the ground layer, this way rain water is encouraged to drain below.

Once you have placed all the slabs needed, brushed off the excess mix and checked all the slabs to make sure they are flat, you can go ahead with the shed placement.

Now you have your shed base, the shed can be built and placed on top of the base which offers the even foundation needed to keep the shed stable.

 

Other Shed Base Options

Plastic Shed Bases

A quicker, easier way to lay a base for your shed is to use a grid system plastic shed base.

Create a level surface once again. Lay the plastic shed base and fill with shingle. You are now ready to build and erect your shed on top of the base. At Buys Sheds Direct we sell plastic shed bases in all sizes.

Concrete Shed Bases

Laying a concrete shed base involves the same clearance and levelling of land as with a paving slab shed base. However, you then need to create a frame, fill with stone, mix cement, level and allow to set.
