Retaining Walls
Retaining Wall Construction in Treasure Valley
At C3 Groundworks, we specialize in building strong, long-lasting retaining walls that combine functionality with visual appeal. Whether you need erosion control, structural support, or improved landscaping, our retaining wall solutions are engineered to perform and built to last throughout Boise, Meridian, Nampa, Kuna, and surrounding Idaho communities.
Functional, Durable & Custom-Built Retaining Walls
Retaining walls aren’t just landscape features—they serve a critical purpose. From holding back soil on sloped properties to creating level yard space and preventing erosion, every wall must be precisely engineered to stand the test of time.
We construct a wide variety of wall types, including:
Gravity walls (block or boulder)
Reinforced concrete walls
Segmental retaining walls
Timber and natural stone walls
Engineered structural walls with geogrid reinforcement
Whether you’re building for looks or for load-bearing function, we’ll guide you through the best solution for your property and budget.
Engineered for Stability & Code Compliance
At C3 Groundworks, we don’t cut corners. We follow best practices in site preparation, drainage, and soil reinforcement to ensure each wall is structurally sound and properly permitted where required.
Our process includes:
Site evaluation and slope analysis
Drainage and water flow planning
Soil compaction and base preparation
Expert block or concrete placement
Geogrid and backfill installation
Clean finishing and grade restoration
Every wall we build is engineered for Idaho’s challenging soil and weather conditions, preventing long-term shifting, cracking, or failure.
Residential & Commercial Applications
From backyard retaining walls to large-scale commercial grade slope support, we serve clients of all sizes. Our walls are ideal for:
Sloped yard stabilization
Raised garden beds
Driveway and parking lot leveling
Basement and hillside support
Property boundary enhancement
We collaborate with landscapers, developers, and general contractors to ensure every project stays on schedule and on spec.
