Sand Under Pea Gravel

Sand under pea gravel is important for creating a stable, well-draining, and low-maintenance surface. This landscaping method is especially useful for walkways, patios, and garden paths. A properly installed sand layer helps prevent gravel movement, improves comfort underfoot, reduces weed growth, and extends the life of your outdoor space.

Why Use Sand Under Pea Gravel?

When installed correctly, sand forms a compact base that prevents pea gravel from shifting or migrating over time. This is critical in areas with foot traffic or frequent rainfall. Gravel migration occurs when stones move away from their intended location, leading to ruts, bald spots, or spreading beyond path borders.

In addition, sand improves drainage by allowing water to pass through efficiently. This reduces puddling and helps keep your gravel surface dry and usable—even after a storm.

Weed Control Benefits

A sand base makes it harder for weeds to grow up through your gravel. It blocks sunlight and airflow from reaching the soil below, making the environment less hospitable to weeds. While not a complete weed-proofing solution, sand significantly cuts down on maintenance.

Reducing Gravel Migration

Sand’s ability to “lock in” the gravel above helps reduce unwanted movement. Over time, this means fewer stones spilling onto lawns or garden beds, and less gravel needing to be raked back into place.

Compact and Comfortable Surface

A thin layer of sand under the gravel also softens the feel underfoot. It allows gravel to settle evenly and creates a smooth, consistent walking surface without shifting or sinking.
