The Result
Usable yard and defined landscape structure.
A retaining wall turns unusable sloped ground into defined, level spaces. Done in concrete — whether poured concrete or concrete block — the wall resists the soil pressure and drainage forces that cause other wall materials to shift or fail in clay soil over time.
What's Included
What this service covers
- Concrete block retaining walls for residential properties
- Poured concrete retaining walls for larger scopes
- Grade change walls for sloped backyards
- Patio leveling walls to create flat outdoor space
- Landscape separation and garden bed definition
- Driveway cut walls and approach grade changes
- Multi-tiered terracing for steep slopes
Common Situations
When people call us for this work
- Creating usable flat space from a sloped backyard
- Leveling an area for a patio or outdoor living space
- Stabilizing a slope that has been eroding or shifting
- Separating landscape elevation changes with a finished edge
- Replacing a failing wood or block wall
- Managing water runoff across a sloped lot
Technical Standards
What matters for a long-lasting pour.
Not all concrete work is done to the same standard. Here's what we pay attention to on every project of this type.
Drainage behind the wall
Retaining walls in clay soil need proper drainage behind them. Clay that stays saturated creates significant hydrostatic pressure against the wall. We address drainage at installation — weep holes, gravel backfill, or drainage pipe depending on the scope.
Wall height and permits
Walls over 4 feet typically require engineering review or a building permit. We assess wall height requirements at the estimate and flag any permit requirements.
Footing depth
Retaining wall footings in eastern KC's climate need adequate depth — below the frost line to prevent heaving. Walls built on footings that aren't deep enough will move seasonally.
Wall type for the application
Poured concrete walls, concrete block, and segmental retaining wall block each have different applications and appearances. Soil type, wall height, and site conditions determine which is appropriate.
Soil load
The taller the wall and the heavier the soil above, the more structural the wall needs to be. Walls retaining heavy clay soil need to be sized for that specific load.
Tie-ins to adjacent surfaces
Retaining walls often work with a patio pour or walkway above or below. Planning the wall and surrounding concrete together produces better results than adding one after the other.
Eastern Kansas City
Local conditions and what they mean for this work.
Eastern KC's heavy clay soil creates more lateral pressure against retaining walls than sandier soils do. Clay also drains slowly, meaning water can build up behind a retaining wall during heavy rain and stay there longer. Retaining walls in this area need proper drainage features built in — not assumed — to avoid wall failure from hydrostatic pressure. This is particularly true for walls over 3 feet or walls in areas that receive significant surface drainage.

Common Questions
Questions about Retaining Walls
Do I need a permit for a retaining wall in Grain Valley?
Walls under 4 feet in height typically don't require a permit in most municipalities. Walls over 4 feet, walls adjacent to property lines, or walls that affect drainage may require a permit and possibly engineering review. We flag requirements at the estimate.
How long does a concrete retaining wall last?
A properly built concrete or concrete block retaining wall should last 50+ years. The main failure modes are drainage-related — walls without adequate drainage behind them fail faster because of hydrostatic pressure and freeze-thaw cycling in saturated backfill.
What's the difference between concrete block and poured concrete for retaining walls?
Concrete block is common for residential applications up to moderate heights — flexible to install, good drainage characteristics, and works well with most residential landscapes. Poured concrete walls are stronger per foot but require forming and a different installation process. Application determines which is appropriate.
Can you build a retaining wall and a patio at the same time?
Yes. When both are needed, building them together is more efficient and produces better results — the wall height, drainage, and patio grade can all be planned in one scope. This is common for backyard leveling projects.
What causes retaining walls to fail?
The most common causes are inadequate drainage behind the wall (hydrostatic pressure), insufficient footing depth (frost heave), and walls under-sized for the soil load they're retaining. In eastern KC's clay soil, drainage is the most common issue.
