Installing a Skid Foundation

Project Overview

Installing a Skid Foundation

The fastest way to lay a skid foundation for your shed is to set 4x6 or larger timbers on patio pavers that are set in a gravel bed. To keep the timbers from rotting, use pressure-treated wood that's rated for ground contact. If you like, bevel the ends of the timber to dress up the skids. Once all materials are in place, shim between the pavers and the skids to level the foundation. For frost-free ground that drains well, dig trenches 4 to 6 inches deep, fill them with gravel, and rest the timbers on the gravel.

LAY A GRAVEL BED AND PATIO STONES

Remove the grass and dig out an area 3 to 4 inches deep underneath your shed. Fill the excavation with gravel and tamp firmly to create a hard surface. For larger sheds, use a power tamper. Lay patio stones to support the timbers, spacing them 4 feet on center. Position and align the skids using mason's line and batterboards. Shim between the pavers and skids to level one of the skids. Put a straight 2x4 across the skids and level them with each other at one end of the shed. Shim the second skid to level it along its length.
