Q: When does a slope need a retaining wall?

• <div><p>To maintain the integrity of your landscape, a retaining wall must be installed if the slope of the angle exceeds 35 degrees. The lean of the wall must be 1 inch per 12 inches in height to disperse the weight of the soil uniformly and guarantee the correct drainage of the soil.</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: Does a small retaining wall need a foundation?

• <div><p>Small retaining walls still require a foundation of some kind, typically a concrete footing. This helps to ensure the wall is structurally sound and prevents the ground from shifting over time, especially during those winter freeze/thaw cycles. The footing helps spread the weight of the wall and the load it carries over a larger area of the ground, thus assisting with stability. This is true of small retaining walls, <a href="https://www.angi.com/articles/rock-garden-ideas.htm">larger rock garden</a> walls, and the like. </p></div>

Q: How do professionals ensure durability in wall construction?

• <div><p>Through proper drainage solutions and compacting the foundation soil.</p></div>

Q: Why do retaining walls lean?

• <div><p>Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.</p></div>
