Soldier pile wall construction installs vertical piles and lagging to retain soil during excavation. Ruffhouse builds these walls for commercial and industrial sites across Washington and Oregon — often as part of a broader earthworks package.
Construction sequence
- Mobilize and lay out pile locations from the approved plan
- Install soldier piles to design embedment
- Excavate in lifts and place lagging between flanges
- Backfill/compact behind panels; add bracing or tiebacks when required
- Document as-built conditions for the GC and engineer
Where this method fits
- Urban lots with limited setback
- Hillside and waterfront cuts in the Puget Sound region
- Basements, podium excavations, and infrastructure trenches needing vertical retention
