Gravity Retaining Walls

Self-Supporting retaining walls rely on their weight to resist soil pressure, making them ideal for low-height walls under four feet. These are commonly built using stone units, offering cost-effective solutions for basic erosion control in residential settings. While simpler to design, they still require proper base preparation to prevent shifting over time.

• Build with solid materials like concrete for maximum performance
• Verify adequate compacted gravel base to prevent settling

Reinforced Retaining Walls

Reinforced concrete retaining walls use a reinforced concrete stem and footing to withstand lateral soil forces, making them perfect for elevated installations in both home and commercial landscapes. These walls deliver superior load-bearing capacity, especially when integrated with permeable backfill. A certified masonry contractor in Bellevue will ensure compliance with stormwater compliance during construction.

Driven Retaining Wall Systems

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

• Perfect for loose soils and restricted installation zones
• Typically made from corrugated metal for longevity

Anchored Retaining Wall Systems

Tieback walls use steel rods or cables anchored into stable soil or bedrock behind the wall face, providing superior strength for critical applications. These are frequently used in engineered retaining walls projects across Bellevue’s hilly terrain. When paired with interlocking blocks, they deliver unmatched resistance to failure.
