If you want to stop dirt from washing away and create a better outdoor space, a retaining wall is a great solution. But which type is best? The two most common options are stacked pavers and stucco over concrete blocks (CMU walls).
Both options have pros and cons. In this guide, we’ll help you understand the differences, costs, and durability so you can choose the right wall for your yard!
What is a Retaining Wall?
A retaining wall is a strong wall that holds back soil and helps prevent erosion, flooding, and uneven ground in your yard. People build them to create flat areas for patios, gardens, or driveways.
There are many types of retaining walls, but the two most popular are:
- Stacked Paver Retaining Walls – These are made of heavy interlocking blocks and are stacked without mortar (no glue or cement).
- Stucco Over Concrete Block Walls (CMU Walls) – These are built with concrete blocks, rebar (steel bars), and mortar for extra strength.
Stacked Paver Retaining Walls
Pros (Good Things) About Stacked Paver Walls
✅ Looks Great – Pavers come in many colors and styles to match your home.
✅ DIY-Friendly – No mortar is needed, so these are easier to install.
✅ Good Drainage – Water can flow between the blocks, helping prevent damage.
✅ Easy to Repair – If one block cracks, you can replace it without tearing down the whole wall.
✅ Affordable – Great for small walls (under 3 feet) on a budget.
Cons (Downsides) of Stacked Paver Walls
❌ Not Good for Tall Walls – If your wall is over 3 feet, it may lean or fall over.
❌ Can Move Over Time – Pavers need a solid base and drainage system or they may shift.
❌ Limited Strength – Pavers are not great for holding back heavy soil or slopes.
Best for: Small garden walls, flower beds, and decorative walls under 3 feet.
Stucco Over Concrete Block (CMU) Walls
Pros (Good Things) About CMU & Stucco Walls
✅ Super Strong – Built with steel bars, concrete, and mortar, making them very durable.
✅ Great for Tall Walls – Can be built over 3 feet without shifting or falling.
✅ Waterproof – Properly built CMU walls resist water damage and cracks better than stacked pavers.
✅ Smooth, Custom Look – Stucco can be painted to match your home for a modern look.
✅ Best for Sloped Yards – CMU walls work great for tiered landscapes and steep slopes.
Cons (Downsides) of CMU & Stucco Walls
❌ More Expensive – CMU walls cost more than stacked pavers due to materials and labor.
❌ Harder to Repair – If a stucco wall cracks, repairs take more time and money.
❌ Takes Longer to Build – CMU walls require more prep work and curing time than pavers.
Best for: Large retaining walls, sloped backyards, or areas that need extra strength and durability.
Which Retaining Wall is Best for You?
Choose stacked pavers if: You need a small, decorative wall under 3 feet.
🔹 Choose CMU with stucco if: You need a strong, long-lasting wall that holds back a lot of soil.
🔹 Live in a flood-prone area? A CMU wall is best because it resists water damage.
