Gravity Retaining Walls

Gravity retaining walls rely on their weight to resist soil pressure, making them ideal for shorter walls under four feet. These are commonly built using heavy masonry, offering budget-friendly solutions for basic yard grading in residential settings. While simpler to design, they still require proper drainage setup to prevent shifting over time.

• Build with heavy materials like concrete for maximum performance
• Ensure adequate drainage layer to prevent settling

Cantilever Retaining Walls

Cantilever retaining walls use a reinforced concrete stem and footing to counteract lateral soil forces, making them perfect for taller installations in both home and commercial landscapes. These walls deliver high-level structural integrity, especially when integrated with permeable backfill. A certified masonry contractor in Bellevue will ensure compliance with stormwater compliance during construction.

Thin-Sheet Retaining Wall Systems

Sheet pile retaining walls are best suited for tight spaces and soft soils, often used in commercial waterfront or urban retrofit projects in Bellevue. These slender walls are driven deep into the ground to stabilize unstable slopes where space is restricted. Though less common in residential yards, they’re a go-to for foundation support situations requiring rapid deployment.

• Ideal for soft soils and narrow installation zones
• Commonly made from corrugated metal for longevity

Tieback Retaining Wall Systems

Cable-reinforced walls use steel rods or cables anchored into stable soil or bedrock behind the wall face, providing extreme strength for tall applications.
