Varieties of Retaining Structures

Mass-Based Soil Retention Systems

• Ensure a properly graded base to balance weight evenly

Structural Beam Wall Designs

Concrete T-shaped systems offer advanced structural integrity for commercial projects. These systems use a reinforced stem and footing, often with geogrid reinforcement to support greater lateral pressure.

Great for steep slopes, these installations require certified plans and are frequently used in multi-level yard projects across Puget Sound.

Anchored Stabilization Builds

Cable-reinforced walls deliver unmatched strength for high-risk slopes. These systems use steel rods or cables anchored into solid soil or rock, connected to the retaining panel
