A sloped yard can become your favorite feature with the right retaining wall. Here are the main options and what makes a wall last.
Segmental concrete block
Interlocking blocks are strong, affordable and come in many colors and textures. They're the most popular choice for residential walls.
Natural stone
Moss rock, boulders and stacked flagstone give a natural Colorado look that blends with native landscaping.
Poured concrete
Smooth concrete walls look modern and can double as built-in seating around patios or sunken spaces.

Drainage is everything
Water pressure behind a wall is what pushes walls over. Every wall should have a compacted base, clean drainage gravel behind it and a way for water to escape, such as a perforated drain pipe.
Height and permits
Taller walls, or walls supporting driveways or structures, may require engineering and a permit. Rules differ by city across the metro, so check before you build.
- Terrace a tall slope into two shorter walls.
- Add planting beds on each level.
- Finish with sod, rock or a patio on the new flat area.
