You've picked your shed — now comes the step that determines whether it lasts 5 years or 30: preparing the site. A storage shed is only as solid as the ground beneath it, and here in coastal Georgia, with sandy soil, a high water table, and heavy seasonal rain, getting the foundation right matters even more. As Savannah shed builders with over 36 years of experience, we've delivered thousands of buildings across Savannah, Pooler, Richmond Hill, and Chatham County. This guide walks you through exactly how to prep your site so delivery day goes smoothly and your shed sits level, dry, and stable for decades.
Why Site Prep Matters (Especially on the Coast)
Placing a shed straight onto bare grass or dirt is one of the most common — and costly — mistakes we see. Without a proper base, the building can settle unevenly, doors and windows start to stick, and moisture wicks up into the floor and framing, leading to rot and mold. Savannah's humidity and frequent downpours make drainage the number one priority. A good foundation lifts your shed off wet ground, channels water away, and keeps the underside ventilated so your building stays sound year-round.
Choosing the Right Foundation
For most Savannah homeowners, a gravel pad is the best all-around choice. It drains beautifully — critical in our climate — it's affordable, it's quick to install, and it works for everything from small garden sheds to large workshops. A typical gravel base uses compacted ¾-inch crushed stone over landscape fabric, contained by a pressure-treated timber border.
A concrete pad is the heavy-duty, permanent option, ideal for large buildings, garages, or anything you want a sealed, flat floor for. It costs more and takes time to cure, but it's rock-solid.
Concrete blocks can work for smaller sheds on fairly level ground, but they offer the least support and aren't our first recommendation for the coast. When in doubt, gravel is the sweet spot of drainage, durability, and value.
Picking and Measuring the Spot
Choose a high, dry area of your yard with good natural drainage — avoid low spots where water pools after a storm. Mark out your foundation footprint about one foot larger than your shed on every side; this extra margin improves airflow and keeps roof runoff from splashing back onto the siding. Use stakes and string to outline the pad, then measure corner-to-corner diagonally both ways — equal measurements mean your base is square.
Keep the pad at least two to three feet from fences and property lines, and check your Chatham County zoning and any HOA rules before you build, as larger sheds or permanent foundations can require a permit.

Getting the Base Level and Draining
A level base is non-negotiable — even a slight slope leads to a misaligned shed and sticking doors. For a gravel pad, frame the perimeter, fill with crushed stone, rake it out to all corners, and compact it firmly so it won't shift under the weight of the building. Use a long board and a level across the top to confirm it's flat in every direction.
To beat Savannah's moisture, slope the surrounding ground gently away from the pad so rainwater drains off rather than collecting underneath. If your yard is especially wet or clay-heavy, a gravel perimeter or simple drainage channel adds cheap insurance against future problems.
Clearing the Path for Delivery Day
Our delivery trucks and trailers need clear, wide access to your site. Before we arrive, remove branches, brush, debris, and any obstacles along the route and around the pad. Make sure overhead limbs are well clear, gates are wide enough, and there's room for the truck to maneuver and pull straight out.
If you're unsure whether your access works, just ask — our team has navigated thousands of Savannah-area properties and we're happy to talk it through ahead of time. Finishing your prep a week or so before delivery keeps everything on schedule.
