Gravity Retaining Walls
Massive retaining walls rely on their mass 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 footing excavation to prevent shifting over time.
- Construct with substantial materials like concrete for maximum stability
- Verify adequate compacted gravel base to prevent sinking
Concrete Retaining Walls
Reinforced concrete retaining walls use a reinforced concrete stem and footing to resist lateral soil forces, making them perfect for elevated installations in both home and industrial landscapes. These walls deliver superior load-bearing capacity, especially when integrated with permeable backfill. A certified masonry contractor in Bellevue will ensure compliance with King County regulations during construction.
Thin-Sheet Retaining Wall Systems
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 support unstable slopes where space is constrained. Though less common in residential yards, they’re a go-to for foundation support situations requiring rapid deployment.
- Ideal for loose soils and cramped installation zones
- Commonly made from corrugated metal for longevity
Cable-Supported Retaining Wall Systems
Anchored walls use steel rods or cables anchored into stable soil or bedrock behind the wall face, providing maximum strength for tall applications.
