Site Preparation for Sheds

One of the most important things to consider when purchasing a storage shed is a sturdy foundation. Most manufacturers include a warranty on your shed that is voided if foundation specifications are not met. It is highly recommended to hire a contractor for professional and successful installation.

Level Site

The pad must be square & level over the entire pad. Sheds require a level surface to allow the windows and doors to open any close properly.

Size

The pad should be at least 2 ft longer and 2 ft wider than your shed creating a 1ft boarder around your shed. This allows for proper drainage and keeps vegetation from growing against your building. Having vegetation against the structure, increases your chance of moisture rotting the bottom.

Shed Base options.

Stone Base – This is your most cost-effective option. Simlawn will confirm the size of your shed and the prep size needed, dig the Sod layer off of your site and install 5-6 inch thick base of 57 Limestone. This will also include hauling away the leftover debris.

Timber Frame – Timber frame bases are quite popular for sheds. They provide a strong platform and are less likely to sink overtime. We use the same process as the stone base when it comes to digging the sod layer off and removing it from your site. 6×6 Treated lumber is lag bolted together to create the frame matching your shed size and leveled. We then backfill the whole structure with 57 limestone including the 1ft perimeter around the base. Pricing for this option varies a lot depending on site conditions and the lumber market.
