Retaining Wall Installation
Segmental and engineered retaining walls that prevent erosion, create usable space, and add lasting value to commercial property.
For homeowners: we build large, engineered residential walls. Patios and smaller hardscaping route to our sister company, Sequoia Stonescapes.
What a segmental retaining wall does for a commercial site
Segmental block retaining walls prevent soil erosion, create usable level space, and provide structural support across grade changes on commercial properties.
PacWest installs engineered wall systems with the drainage, geogrid reinforcement, and compaction that commercial sites require, so the wall performs for decades.
- Engineered, code-compliant systems
- Drainage and geogrid reinforcement
- Proper base prep and compaction
