Level the ground for your new metal carport or custom metal building

So you’ve chosen a quality metal carport and picked out the perfect spot for it. What now? Whether you have purchased a metal carport kit or are planning on having it professionally installed, it’s important to level your site before the first pole is placed.

Why leveling your site is important

If your carport site is more than four inches or so out of level, you could be asking for trouble. Your carport could end up leaning to one end or one side. If not balanced, it could become top heavy, making it more susceptible to pulling up anchors during a good windstorm. This could compromise not only your carport, but also the contents within it. If you have a steel carport with enclosure or another type of metal building structure, all components—roof panels, sides, and ends—need to line up properly or your walk-in or garage doors may not open properly. You are also inviting various animals (snakes, mice, and other critters) to find their way through the gaps into your enclosure.

Carport Base Options

Depending on what you will be using your carport for, you can go with a couple of options.

Concrete Carport Foundation

A concrete slab has many benefits for your steel carport. Unlike using a dirt floor or gravel, concrete does a better job protecting your precious storage. For example, tires that sit in standing water or mud can suffer unnecessary wear and tear, which can become costly over time—especially if you are sheltering a larger vehicle. Concrete will keep your contents drier and cleaner. If you have an enclosed portion on your carport, it will ensure protection against various critters as well.

Gravel Carport Foundation

This is a simple gravel base for the carport floor. Over time the gravel will shift and develop trenches which can be easily re-leveled. This is a more cost effective option if you are on a tight budget or if you are sheltering items that don’t require as much TLC.

How to level an area for your metal carport

  1. Check for Utility Lines and Clear the Area

Check with your local utility companies before you get started to make sure you don’t run into any gas or water lines. Once you are cleared, you can start by removing shrubs, grass, and other plants in the area.

  1. Measure and Mark the Area

Using measuring tape, measure the area where you will be installing your metal carport. Be sure that the area you are measuring is slightly larger than the actual structure. Use a spray paint to mark the perimeter.

  1. Place Stakes at All Four Corners

Place the ground stake in your first corner, and then use measuring tape to measure to the second corner. Place the second stake. Repeat the process until all four corners are marked. If you are going to lay down a concrete pad, you will have to square your site. (We won’t cover squaring in this post, but instructions are readily available on the web.) Otherwise, as long as your site is pretty well “squared,” you should be good to go.

  1. Level the Sides with String or Twine

Once you have staked your four corners, find the stake that appears to be at the highest point. Measure a set number of inches from the ground and tie your string there. (We will use four inches for this example.) Choose your next stake and tie the string at the height where it seems to be level with the height of the first stake. Place a line or string level in the middle of your length of string. Adjust the line by adjusting the string on the second stake up or down until the bubble in the site glass of the level is in the middle.

  1. Measure Your High/Low Points to Find the Difference

Once your string is level, measure the high point (which should be four inches) and your low point and figure the difference. For example, if your string is four inches high at one end and six inches at the other, you have a difference of two inches. This would be an acceptable slope for basic metal carport designs, but in the case of more complex steel carport plans, metal barns, or other metal buildings, you would need to add dirt to the low point or remove dirt from the high point to eliminate the slope so that your structure can be anchored securely. Repeat this step for the other three corners to be sure that your entire site is level. Now you are ready for your gravel or concrete.

By leveling your site prior to installation, you can avoid costly problems. Most metal storage building installers will not install your metal structure if the site is not reasonably level, requiring you to pay additional delivery and/or installation charges for a second trip out. Also, you could compromise your new metal structure by putting undo pressure on one side or causing gaps which lead to a variety of other problems.
