Keystone Retaining Walls: What They Are and Why You Might Need One

Got a sloped section or an awkward corner of the garden you can’t use? A keystone retaining wall might be the solution. These solid, interlocking blocks are designed to hold back soil, shape your section, and make the most of your space—all while looking clean and tidy.

What Is a Keystone Retaining Wall?

Keystone blocks are engineered concrete units that lock together to form a stable retaining wall—no mortar required. Their clever design means they can be built quickly, curved to suit your space, and reinforced where needed for extra strength.

You’ll often see them used on:

• Sloping driveways

• Tiered garden beds

• Backyards with elevation changes

• Commercial landscapes and boundary edges

Why Choose Keystone?

• Strong and stable – Holds back soil, prevents erosion, and manages water flow

• Flexible design – Can follow curves, corners, or straight lines

• Tidy, modern finish – Clean edges and block texture look sharp

• Low maintenance – No cracking or shifting like poured concrete walls

• Drainage-friendly – Designed to handle water buildup behind the wall

Do You Need a Retaining Wall?

If you’ve got:

• Sloping land you can’t use

• Erosion or slipping soil after heavy rain

• A landscaping project that needs strong structure

• Plans for a driveway or patio on a slope

...you’ll likely benefit from one. And it’s better to get it done right the first time.
