Overview

Crushed stone provides stability in many landscaping and building projects. Whether you're laying stone for a patio, or putting in a stable footing for a foundation wall, many building projects suggest crushed stone as an early step in the process. The angular edges of crushed stone interlock more than sand or pea gravel and provide more stability. You can purchase crushed stone from many big-box home improvement stores, as well as contractor supply stores.

Step 1

Remove a layer of sod from the surface of the soil using a sod cutter.

Step 2

Remove the soil in a layer that extends below the frost line for your region to prevent damage to the footing, patio or pathway that can be caused from frost heave. Foundation wall footings are typically 24 inches wide, while landscaping trenches follow the shape of the finished landscape project.

Step 3

Insure that the soil in the bottom of the excavation is level by laying a plywood board across the bottom of the soil. Place a carpenter's level over this to measure.

Step 4

Tamp down the soil using a soil-tamping tool.

Step 5

Cover the soil with crushed stone in a 4-inch layer. Tamp down the stone using your stone-tamping tool.

Step 6

Spread a ½-inch layer of damp, coarse sand over the stone. Level the sand and use the board and carpenter's level to measure.

Step 7

Tamp down the sand over the crushed stone using the tamping tool.

Step 8

Lay paving bricks or foundation bricks for your wall over the tamped-down sand.
