Reinforced Strength
Retaining Walls & Structural Concrete in the Treasure Valley
From decorative retaining walls to structural concrete reinforcements, C3 Groundworks delivers durable solutions designed to hold back earth, support loads, and protect your property. Whether you’re managing slope, soil erosion, or need structural support, we build with strength, safety, and precision.
Built to Withstand Pressure
Retaining walls do more than look good—they hold back tons of pressure from soil and water. That’s why we engineer every wall we build with proper footing depth, drainage, and reinforcement. Whether you’re dealing with a sloped yard, need a boundary wall, or supporting a load-bearing area, our concrete structures are built to code and built to last.
We work with both residential and commercial clients to construct:
Concrete Retaining Walls – Functional and beautiful walls for slopes, yards, or raised areas
Structural Reinforcement Walls – Load-bearing concrete walls for garages, basements, and property lines
Grade-Level Support Walls – For patios, driveways, or terraced landscaping
Drainage & Backfill Solutions – Prevent water damage and soil erosion
When You Need More Than Just Looks
While decorative block walls may look nice, true structural concrete retaining walls offer the durability required for safety and longevity. We install rebar-reinforced concrete walls with proper drainage and deep footings, ensuring your investment remains rock solid through Idaho’s freeze-thaw cycles.
