Quality Handcrafted Outdoor Garden Storage Sheds in Ottawa Ontario Canada.

Base Preparation

A proper base is important for your shed, gazebo or garage for two main reasons:

  • The structure needs to sit on a solid, level surface to remain stable and for the doors and/or windows to operate properly.
  • The structure needs to sit slightly off the ground to allow for proper water drainage and minimize moisture transfer from the ground to the structure.

There are several types of shed foundations, and the kind you need may depend on where you live, the size of your shed, and its intended use. The following are the most common methods:

Our recommended base is ¾ inch clear stone, to a depth of 4-6 inches minimum. This can be above or below grade, finished to the height of the existing grade.

We also recommend that landscape material be placed prior to the stone to prevent weeds, etc. from coming through.

Option 3: Patio Blocks

This only applies to a shed with two runners, as you will be able to access the patio blocks and level them with shims after the building is in place.

Setting the shed on patio blocks is the most economical option, where 1” thick, 12”x12” patio blocks are placed under each runner, at three-foot intervals.

The building gets placed onto the patio blocks, then it is jacked to a level position and the blocks are then shimmed so the building rests fully supported on the blocks.

Note: Patio blocks are to be used in this option, NOT cinder blocks. Inevitably, there will be some settling after your shed is delivered and placed on site. Placing a shed on cinder blocks greatly increases the risk that your shed will settle unevenly. This can create twisting and offset door and window frames. Additionally, delivery and placement of the shed can be made more difficult with cinder blocks as a base.

Even experienced DIYers may have questions or encounter challenges when building a shed foundation. Therefore, we recommend hiring a qualified building professional.
