Do You Need a Retaining Wall? Here's How to Tell

If you’re thinking about upgrading your yard, you’ve probably come across the term “retaining wall.” These strong walls do more than just look nice. They help shape your yard and protect it. For landscaping in Des Moines, where sloped yards and heavy rains are common, a retaining wall can be more of a need than a want.

But how can you tell if your yard actually needs one? Here are some signs it might be time to consider adding a retaining wall.

Your Yard Slopes and Feels Hard to Use

One of the most common reasons people install retaining walls is because their yard isn’t flat. If your backyard feels like a hill, you’re losing space you could use. Steep areas can be hard to mow, tricky to landscape, and even unsafe for kids or pets.

A retaining wall helps flatten those areas. It holds back the slope and gives you level ground to enjoy. That could mean space for a patio, a garden, or just a flat spot for lawn chairs. Instead of struggling to use your yard, you get a space that fits your life.

Water Pooling or Drainage Issues

If water collects around your home after it rains, or you’ve noticed puddles where they don’t belong, your yard’s drainage isn’t working well. You might also see mulch washing away or water running too fast through certain areas.

These are signs that a retaining wall could help. It can slow down and redirect water, protecting your landscape and your home. Water damage can sneak up on you. Fixing the problem early can save you money down the road.

Bare Spots or Erosion in the Yard

Have you seen patches where grass won’t grow? Or noticed dirt disappearing after heavy rain? That’s erosion, and it means your soil is moving.

Erosion doesn’t just mess up your yard—it can lead to bigger problems. Soil slipping away near fences, sheds, or your house can cause cracks or shifting. A retaining wall holds the soil in place so your yard stays stable. It also helps keep your topsoil, which makes it easier to grow plants and grass.

Cracks in Sidewalks, Patios, or Foundations

If you’re seeing cracks in your sidewalks, driveway, or patio, or if your basement walls are starting to bow, that’s a red flag. It could mean the soil is pushing too hard against those surfaces.

Over time, that pressure builds up. A retaining wall helps stop that push. It supports the soil and relieves stress on your hardscape and your home. If you’re already seeing signs like this, don’t wait too long. Fixing the problem early can prevent more serious damage.
