What is the Purpose of a Retaining Wall?

If your yard has a slope that acts more like a slip-n-slide every time it rains, you’ve probably wondered if a retaining wall is right for you. Retaining walls aren’t just a “fancy landscaping thing.” They’re a smart, practical way to protect your property, control water, and make outdoor spaces more usable. At The Southern Landscape Group, we help homeowners understand when a retaining wall is a nice-to-have, and when it’s quietly saving your yard from future chaos.

What is the Purpose of a Retaining Wall?

What Does a Retaining Wall Actually Do?

A retaining wall is designed to hold back soil and stabilize elevation changes. In other words, it keeps a sloping lawn from creeping, collapsing, or washing away. It creates structure where your yard naturally wants to shift, especially during heavy rain seasons or freeze-thaw cycles that loosen soil over time.

Can I Just Use Mulch?

Mulch is great, but it can’t stop erosion on a steep slope. If you’re seeing exposed roots, bare patches where grass won’t grow, or soil that seems to migrate downhill, those are signs your yard needs more than cosmetic fixes. A retaining wall can stop the erosion cycle and give your landscape a stable foundation to build on.

Can a Retaining Wall help with Drainage?

Yes—when designed correctly. Retaining walls can redirect water, slow runoff, and work alongside drainage solutions such as French drains or catch basins. The key is proper construction: drainage gravel, weep holes, and the proper grading behind the wall. Without those, a wall can trap water and create pressure (which is how you end up with a leaning wall and a bad day).

Do Retaining Walls Only Exist for Function, or Can They Look Good, Too?

Retaining walls add clean lines, dimension, and definition to your yard. They can create leveled areas for patios, seating spaces, garden beds, or walkways—turning “awkward slope” into “intentional outdoor design.” Materials like natural stone, block, or timber can be chosen to match your home’s style.

How Do You Know What Type of Retaining Wall is Right for Your Yard?

It depends on your slope, soil type, drainage patterns, and what you want the space to do. Some walls are purely structural. Others are more decorative but still help control erosion. A professional assessment helps you avoid overspending—or underbuilding.
