Site Preparation & Installation

Whether you purchase a shed, gazebo, horse barn, pergola, gazebo or pavilion from Backyard Unlimited, our own experienced installation crew will deliver and install your new structure. All of our guys are friendly, hard working and eager to please you!

To ensure that the installation and setup goes smoothly, some site preparation work will need to be completed before the scheduled install. The type of site preparation required will depend on the structure you've purchased. To help you prepare, we've put together this site preparation guide that outlines the steps you should take before we install your new structure.

Building Site Preparation

(includes sheds, horse barns, pool houses, garages, dog kennels, chicken coops, play houses and gazebos with floors)

The foundation is the unsung hero of the backyard building. Though it often goes unnoticed, the foundation ensures that your structure will stand the test of time. The least expensive and easiest foundation option for most buildings is a gravel pad. Here are some basic guidelines for creating your gravel pad foundation:

  • Create a level frame with 4x4 or 4x6 pressure treated wood
  • Frame can be up to 12" wider and longer than your building dimensions
  • Evenly fill the frame with 4-6" of 3/4" crushed gravel (available from most landscape supply retailers)

Site Preparation for Other Structures

(includes gazebos without floors, pavilions and pergolas)

Structures that don't have a base or floor need to be anchored so they stay in place. We'll anchor the posts of your new structure to either a concrete slab or concrete footers. Here are the guidelines for concrete installation.

Concrete Slab

Most gazebos without floors, pavilions and pergolas can be anchored to a simple concrete slab with a 4" depth.

  • Create a level frame and fill with 4" of concrete
  • Frame can be up to 12" wider and longer than your structure dimensions
  • Allow adequate time for the concrete to cure completely before your scheduled installation

Your installer will anchor the posts directly to the concrete slab.

Please note: Pavilions that exceed 10'x12' should be anchored using concrete footers described below.

Footers

If you have an existing paver patio or have other plans for the area underneath your gazebo, pergola or pavilion you may wish to install concrete footers, instead of a full slab of concrete. We can attach your new structure directly to these footers.

Please note: Pavilions over 10'x12' should be anchored to concrete footers with a minimum depth of 12"

  • Consult the post layout diagram for the building you have purchased. Don't have a diagram for your structure? Just contact us!
  • Using the measurements in the post layout diagram, dig post holes to a depth of at least 12"
  • Fill the post holes with concrete
  • Allow adequate time for the concrete to cure completely before your scheduled installation

Your installer will anchor the posts of your new structure to the concrete footers.
