What is the best material to fill behind a retaining wall?

• <div><p>Sand and gravel are two suitable options for filling behind a retaining wall. If you’re building your own retaining wall, you’ll complete this part of the process—known as backfilling—after you finish laying the blocks. Make sure not to skip it—otherwise, you could wind up with drainage issues, which can cause your retaining wall to collapse.</p></div>

Q: What happens if you don't backfill a retaining wall?

• <div><p>If you don&rsquo;t backfill a retaining wall&mdash;either at all or adequately enough&mdash;the wall won&rsquo;t drain well, and water will be able to pass through it. Poor drainage will lead to a warped wall or a buildup of hydrostatic pressure, which can eventually collapse your retaining wall. If you have particularly sloped land, consult a structural engineer to ensure your <a href="https://www.angi.com/articles/hardscape-features-bring-value-landscape.htm">hardscaping is adding value to your home</a>.</p></div>

Q: How high does a retaining wall have to be?

• <div><p>Generally speaking, a retaining wall should be between 3 and 4 feet high, depending on variables such as the wall-building material, the purpose of the retaining wall, and more. If you want your retaining wall to be taller than 4 feet, check with your local building ordinance office for the maximum allotment. You may also need a special permit for retaining walls over 4 feet tall.</p></div>

Q: Can a retaining wall be a pool fence?

• <div><p>A <a href="https://www.angi.com/articles/what-is-a-retaining-wall.htm">retaining wall</a> can only function as a fence if it&rsquo;s high enough on all sides to prevent someone from accidentally falling into the pool. However, most retaining walls retain dirt, which means their purpose is not related to safety. There would need to be nothing on the other side of the wall for it to be considered a fence, but in that case, it wouldn&rsquo;t retain anything and would cease to be a retaining wall. </p></div>

Q: Are there decorative options for retaining walls?

• <div><p>Yes, including patterns, finishes, and plant integration for aesthetic enhancement.</p></div>
