How to lay a base for your shed

How to choose a base for your shed

Once you have chosen your steel shed and decided where it will go in your garden, you need to prepare a solid and level site if not already in place. It is crucial that you provide a level and dry foundation. If your shed base is not level, or subsides over time, the screw holes connecting the wall panels will not line up. The structural integrity of your metal garden shed will suffer. Slowly, but surely you will find leaks at the base frame, panels breaking, and doors sticking.

We also recommend that you lay a damp-proof membrane under your solid, level base. This will decrease the chances of your shed being affected by condensation in the Winter Months.

So choosing a base for your Steel Shed is very important.

Two of the main types of base suitable for a metal garden shed are:

• A Concrete Base
• A Paving Slab Base

Whichever method you decide to choose, we advise you allow a 2-inch (5 cm) lip around the base of your garden shed. To calculate the size of base required for the particular shed you wish to build, add 4 inch to the overall base dimensions to ensure an adequate base size. All of our shed dimensions can be found in the images of each product.
