What are the best ways to prepare the site for a shed, gazebo or garage?
Option 1: A crushed stone pad. To prepare a stone pad, remove the sod from an area slightly larger than the pad, level the site by removing dirt where necessary, and spread ¾” crushed stone to a depth of 3” & 4”. Tamp the stone down with a piece of 4-by-4 or metal tamper until it is evenly distributed and the site is flat and level. The pad should be 1’ larger all the way around than the shed. For example, a 10’ x 14’ building would require a stone pad of at least 12’ x 16’. This allows for better drainage around the perimeter of the shed for rain/snow melt dripping off the eaves. Water splashing directly onto the ground will, eventually, create a muddy area and splash up onto the shed walls. Note: A “frame” of pressure-treated 4x4’s or cement block will help keep the stone in place and create a neater appearance.
Option 2: A concrete slab. A level concrete slab between 3” – 4” thick and at least a foot larger than the building in length and width, as with the gravel pad.
Option 3: Setting the shed on patio blocks. This is the most economical option where 2” thick, 8” x16” patio blocks are placed on the four corners of the shed. The shed is set on to a level ground with jacks set underneath. The shed is then raised up on the jacks and patio blocks are placed under the corners of the shed. The shed is then lowered on to the patio blocks and the jacks are removed. Note: That patio blocks are used, not cinder blocks.
Option 4: Cement pillars. Cement pillars, with or without tie-downs, are required by some municipalities. Check local regulations for quantity and recommended placement
NOT RECOMMENDED: 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 shed can be with more difficult with cinder blocks as a base. |
