Q: What is the cheapest way to build a retaining wall?

• <div><p>Poured concrete is likely the cheapest way to build a retaining wall, as this material costs anywhere from $6 to $8 per square foot. The next best budget-friendly option is to use landscaping timbers. These timbers are great for DIY projects, as they don&rsquo;t require tools to successfully build a retaining wall. Landscape timber costs around $10 to $14 per square foot. Depending on your <a href="https://www.angi.com/articles/garden-styles-your-backyard.htm">chosen garden style</a>, you can also go with natural stones or concrete blocks. Natural stones can be expensive if you buy them, but they&rsquo;re a lot less costly if you can source them from your property. </p></div>

Q: How long does it take to build a retaining wall?

• <div><p>Most retaining wall installations can be finished in one to three weeks, but the timeline varies based on factors like wall size and material. The local climate and major weather events, such as storms or flooding, can also extend the project's timeline, as can any holds ups in the permitting process.</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: What is the difference between a foundation wall and a retaining wall?

• <div><p>With foundation walls, the slab on grade and force at the top of the wall is resisted by flooring. With retaining walls, the force at the top of the wall is not resisted.</p></div>

Q: Does a 2-foot retaining wall need drainage?

• <div><p>Each design is different, so we can&rsquo;t say definitively if you&rsquo;ll need a dedicated drainage system in place for a two-foot retaining wall. However, you can likely skip the drainage, as this project is typically served for walls that are 4 feet tall or more. Even with a relatively low wall, consider drainage if you are building on top of clay or poor-draining soil types or if there are buried water sources nearby, like a well used for other <a href="https://www.angi.com/articles/beginning-home-gardening-guide.htm">outdoor garden projects</a>.</p></div>

Repaired my leaking main Second floor bathroom drain piping. Whoever did the original repair/ install obviously wasn’t a pro. Probably a child it was so bad. Mitch did a great repair and not one leak.
