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 Seaford

Garden sheds are a critical aspect of any useful garden space. They can offer storage for heavy garden tools, as well as for other tools. A sizeable garden shed could even provide enough room for plant potting or a general workshop. Additionally, a large shed could be used as an inside seating area. Garden sheds are available in a large range of sizes and can be specified to your exact requirements, giving you total control over the amount and placement of windows, type, size and location of door, and style of roof. Garden sheds normally are available in one of three materials. Wooden sheds are the typical design and can be integrated well into any garden creating a natural look, especially if the wood used for the shed is matched to bordering fences. Wooden sheds are still very popular, although they will demand maintenance by retreating or staining the wood to protect the lifespan of the shed. Garden sheds are also constructed from metal, which is very durable and therefore great for storage of tools and other equipment. Metal sheds also require almost no maintenance. The final material for garden sheds is plastic, which in modern examples is much more resilient than might be expected. When considering a garden shed, it's essential to make certain you choose one that will fit in your garden space. Garden sheds should be placed on a level 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 have to be the right size for your shed and capable of supporting the weight of your shed when loaded.

Try to put your shed in open space, away from trees, bushes and other buildings. This will help to protect it from falling branches and sap. It will also mean that you can access all sides of the shed for repair and maintenance purposes. Make sure you take a look at garden shed planning rules before you pick a final spot for your shed.
