How To Build A Shed Base With Concrete Blocks

Building a shed base with concrete blocks is a relatively simple process that can be done by following these steps:

How To Build A Shed Base With Concrete Blocks

Prepare the site

Choose a level area that is slightly larger than the size of the shed. Mark out the area with wooden stakes and string, ensuring that it is square. Remove any grass or vegetation from the area and dig down about 6 inches.

Add crushed stone

Add a layer of crushed stone or gravel to the bottom of the hole, making sure it is level. Use a tamper or plate compactor to compact the stone and create a stable base. TYPE 1 MOT CALCULATOR

Lay the concrete blocks

Start laying the concrete blocks along the perimeter of the site, using the spirit level to ensure that they are level and even. Continue laying the blocks, ensuring that they are spaced about 3 to 4 feet apart. Make sure that the blocks are level in all directions and that they are aligned with the perimeter stakes.

Fill the gaps

Fill the gaps between the blocks with crushed stone or gravel, making sure it is level with the top of the blocks. Use the tamper or plate compactor to compact the stone and create a solid base.

Mix the concrete

Mix the concrete according to the instructions on the bag. You can mix it in a wheelbarrow using a shovel or use a cement mixer if you have one.

Pour the concrete

Pour the concrete mix into the holes between the blocks, filling them to the top. Smooth the surface of the concrete with a trowel, making sure it is level with the top of the blocks.

Finish the concrete

Let the concrete dry for at least 24 hours, or according to the instructions on the bag. Once it is dry, you can remove the wooden stakes and string and clean up the site.

Your shed base with concrete blocks is now complete and ready to support your shed. Remember to check the level of the blocks regularly and adjust them if needed to ensure that your shed stays level and stable.
