How to Level the Ground for a Shed on Blocks

Updated February 21, 2017

Sheds are useful storage areas for tools, lawnmowers and other outdoor recreation equipment. Sheds are constructed in a variety of methods including directly on a slab, or elevated above the ground on blocks. If you are installing a shed on blocks, one of the first steps is to level the ground under it. A level ground is critical to ensure that the shed does not slant at an awkward angle once installed.

Determine the dimension of the shed either by measuring the length and the width, or by looking at the set-up instructions. Use a tape measure to transfer the dimensions onto the ground and outline the area using spray chalk.

Read the set-up instructions for the shed to determine how many blocks are required and how far apart they must be spaced. Set the blocks in the appropriate locations using the tape measure. Typically, there is a block in each corner but some sheds require more blocks.

Place a level on top of the first block and look at the top of it to ensure the air bubble is centred. If the block is not level, move it aside and use a shovel to dig out the ground to remove any raised area. Replace the block and test it again for levelness.

Repeat the process on each of the remaining blocks to ensure that each of them are level and dig out some soil if needed to accomplish this.

Locate a long board, such as a 2-by-4. Lay one end of the board on one block and lay the other end on one of the other blocks. Place the level on the top centre of the board to ensure it is level. If it is not level, determine which block is higher and dig out additional soil under it until the board is level.

Test each of the additional blocks using the long board, until all of the blocks are at the exact same depth.
