Installing an outdoor bench on soil requires proper preparation to ensure stability and longevity. The recommended foundation depends on your soil type, climate, and whether you want a permanent or movable setup.
For most situations, creating a simple gravel base is highly effective. Start by leveling the area and removing grass or organic material. Dig a trench slightly larger than the bench legs or frame, about 4-6 inches deep. Fill it with compactible gravel or crushed stone, then use a tamper to create a solid, level base. This method provides excellent drainage, prevents frost heave in cold climates, and stops the bench from sinking.
For heavier benches or softer soils, consider using concrete pavers or patio stones set on a sand and gravel base. For a permanent installation in stable soil, you can use concrete footings. Always ensure your final setup is level. This simple foundation work prevents wobbling, protects your bench, and ensures years of comfortable use in your garden.
