Gravity Retaining Walls

Self-Supporting retaining walls rely on their density to resist soil pressure, making them ideal for modest walls under four feet. These are commonly built using heavy masonry, offering affordable solutions for basic yard grading in residential settings. While simpler to design, they still require proper footing excavation to prevent shifting over time.

• Install with substantial materials like concrete for maximum durability
• Confirm adequate drainage layer to prevent sinking

Cantilever Retaining Walls

Cantilever retaining walls use a reinforced concrete stem and footing to resist lateral soil forces, making them perfect for taller installations in both residential and commercial landscapes. These walls deliver exceptional load-bearing capacity, especially when integrated with geotextile fabric. A certified masonry contractor in Bellevue will ensure compliance with stormwater compliance during construction.

Driven Retaining Wall Systems

Driven sheet retaining walls are best suited for limited 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 support unstable slopes where space is restricted. Though less common in residential yards, they’re a go-to for foundation support situations requiring rapid deployment.

• Perfect for loose soils and cramped installation zones
• Typically made from reinforced polymer for longevity

Tieback Retaining Wall Systems

Tieback walls use steel rods or cables anchored into stable soil or bedrock behind the wall face, providing superior strength for high-load applications. These are frequently used in engineered retaining walls projects across Bellevue’s hilly terrain. When paired with concrete retaining walls, they deliver unmatched longevity.
