It depends on the model of your pool. You’ll always have to level the topsoil, but most vinyl-lined pools require an additional 1- to 2-inch layer of sand to protect the liner. This way, when a foot kicks down to the bottom of your pool, it’s not scraping the liner against the hard ground. If your pool isn’t vinyl-lined, you can skip this step or add a layer of another base material, like decomposed granite. Always check your manufacturer’s instructions before you begin.

The right depth depends on your intended use for the area. For instance, pea gravel for walkways and patios typically only needs to be about 2 to 3 inches deep. However, driveways and other areas with heavier loads may require 4 to 6 inches for better stability.

Landscape boulders, especially porous stones like sandstone or granite, can crack or break over time. Cracks occur when water seeps into the surface of the stone and freezes. The risk is highest when it rains during the day and temperatures freeze overnight since the moisture has time to penetrate deeper into the rock before expanding.

The number of bags of topsoil you need depends on the depth you’re filling. The average topsoil is sold in a roughly forty-pound bag, covering 12 square feet at a one-inch depth. Since topsoil is by nature the uppermost layer of soil, you can bet on only needing to fill about 4 to 8 inches of soil depth with it.
