Self-Supporting retaining walls rely on their mass to resist soil pressure, making them ideal for modest walls under four feet. These are commonly built using concrete blocks, offering budget-friendly solutions for basic erosion control in residential settings.

Driven sheet retaining walls are best suited for confined spaces and soft soils, often used in commercial waterfront or urban retrofit projects in Bellevue. These narrow walls are driven deep into the ground to anchor unstable slopes where space is limited. Though less common in residential yards, they’re a go-to for slope repair situations requiring rapid deployment.

Anchored Retaining Wall Systems
Tieback walls use steel rods or cables anchored into stable soil or bedrock behind the wall face, providing maximum strength for high-load applications.
