These vertical 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.
- Excellent for soft soils and restricted installation zones
- Typically made from reinforced polymer for corrosion resistance
Anchored Retaining Wall Systems
Anchored walls use steel rods or cables anchored into stable soil or bedrock behind the wall face, providing extreme strength for tall applications.
