How to build a shed base on uneven ground?

Building a shed base on uneven ground can be as easy as digging out a sub-base and checking that it’s level. You can dig down until the soil is light brown and rather compact, then work out where the ground is uneven and move soil around to compensate. Add a weed-blocking membrane down then put plastic grids in to act as your shed base or continue to make a sub-base for paving slabs or concrete. However, you could also build a timber shed base on uneven ground using concrete blocks to level it out. Mark out the area and dig the top layer of soil, trying to get the ground as flat as possible. Build a timber frame to size. Measure out 4 rows of 3 blocks to create good weight distribution and lay in place. Underneath each block, dig around 50mm wider than the blocks and about 150mm deep. Fill the hole with pea gravel until it’s flat. Place timber planks along the rows of blocks and see how level it is. Add or remove blocks where necessary. If it’s only a small difference, use shingle underneath the timber until it’s level. Nail your timber shed base to the timber planks to create a sturdy base for your shed. If you’ve got any questions about building a shed base on uneven ground, it’s best leaving it to the pros. Get in touch with a range of builders who will be able to offer you a quote.

Garden Sheds in Salisbury

Garden sheds are a significant element of any functional garden space. They provide storage for heavy garden tools, as well as for other equipment. A larger sized shed might even provide enough space for plant potting or a general workshop. Additionally, a substantial shed could be used as an inside seating area. Garden sheds are available in a large variety of sizes and can be specified to your exact needs, providing you with full control over the amount and placement of windows, type, size and location of door, and style of roof. Garden sheds typically come in one of three materials. Wooden sheds are the traditional style and can be integrated well into any garden creating a natural look, especially if the wood used for the shed is matched to neighbouring fences. Wooden sheds are still extremely popular, although they will require maintenance by retreating or staining the wood to preserve the life of the shed. Garden sheds are also made of metal, which is very strong and therefore ideal for storage of tools and other equipment. Metal sheds also require minimal maintenance. The final material for garden sheds is plastic, which in modern examples is much more durable than might be expected. When contemplating a garden shed, it's crucial to make certain you select one which will fit in your garden space. Garden sheds will need to be sited on a flat area, and will need a base to be built as a foundation. This base could be produced from either concrete, paving, gravel or a floating wooden base, but will need to be the right size for your shed and capable of supporting the weight of your shed when loaded.
