Planning to excavate for a basement, subterranean garage, or retaining wall in Los Angeles? Shoring systems are the unsung heroes of safe and efficient excavation. Especially in dense or hillside areas like Pacific Palisades and Malibu, properly engineered shoring is essential to prevent soil collapse and structural movement.
What Is Shoring in Construction and Why Is It Essential?
Shoring supports the earth around your excavation during construction. In urban or sloped neighborhoods where buildings are close together or above cut-and-fill slopes, excavation without shoring can cause cave‑ins or damage adjacent structures. Shoring stabilizes the site, ensuring safety and uninterrupted progress.
Types of Shoring Systems Used in Los Angeles
1. Soldier Pile & Lagging
Vertical steel piles driven into the ground with horizontal wood or concrete lagging between them. Ideal for tight urban lots.
2. Shotcrete with Tiebacks
Reinforced concrete (shotcrete) sprayed onto the excavation face and anchored with tiebacks into the earth. Common in steep hillside cuts like those in Bel Air.
3. Secant or Tangent Pile Walls
Interlocking or overlapping concrete piles form a continuous barrier against soil and water pressure—perfect for coastal zones in Malibu with high water tables.
Key Factors in Designing Your Shoring System
-
- Soil type, slope, and groundwater level
-
- Excavation depth and site access
-
- Equipment requirements (drill rigs, cranes)
-
- Integration with Below Grade Waterproofing and drainage
Planning Tips for Successful Excavation Projects
-
- Start with a geotechnical report: Guides your engineer in a safe, cost‑effective design.
-
- Coordinate with your waterproofing team: Many systems double as foundation walls—plan integration early.
-
- Plan utility penetrations: Include sleeves, pipes, and drains before digging to avoid change orders.
-
- Verify equipment access: Ensure cranes or drill rigs can reach the site.
Common Oversights That Cause Delays and Cost Overruns
-
- Ignoring neighboring foundation loads
-
- Underestimating soil retention needs for deep excavations
-
- Late engineering or permit submittals
Final Thoughts: Safety, Schedule & Budget Control
