Gravity Retaining Walls
Gravity retaining walls rely on their weight 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 yard grading in residential settings.

These walls deliver superior load-bearing capacity, especially when integrated with geotextile fabric. A certified masonry contractor in Bellevue will ensure compliance with Bellevue building codes 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 narrow 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 slope repair situations requiring rapid deployment.
