Shed Site Prep Guide: Gravel Pad vs. Concrete Pad
Last updated June 2, 2026
Most portable buildings need a solid, level base. A crushed-stone (gravel) pad is the most common and economical choice and supports drainage; a concrete pad is more permanent and costly. Either way, keep the pad level and make sure the delivery path is clear and wide enough.
A good foundation keeps your shed level, dry, and lasting. The two most common options are a gravel pad and a concrete pad.
Gravel (crushed-stone) pad
- The most common and economical base for a portable building
- A bed of crushed stone (commonly around 4–6 inches) inside a level border
- Promotes drainage and airflow under the building
- Faster and cheaper to prepare than concrete
Concrete pad
- More permanent and very stable
- Higher cost and more lead time to pour and cure
- Often chosen for garages or heavier use
- May require its own permit in some areas
Keep it level
Whatever base you choose, a level surface is the single most important thing. An unlevel pad can cause doors to bind and stress the structure over time. If you're not sure, ask your dealer what they recommend for your building and soil.
Delivery access
Delivered-fully-built buildings arrive on specialized equipment. As a rule of thumb, the delivery path should be wider than the building, with room to maneuver and clearance overhead (branches, wires) and at gates. Walk the route before delivery day and clear obstacles. Confirm exact requirements with your dealer.
Requirements vary by building, dealer, and ground conditions. Always confirm base and access specifics with your dealer before delivery.
