Build With Bulkhead Repair
The Bulkhead Repair Advantage
When Pressurized Cement Slurry Injection Is the Better Solution
(Pressure Grout • CLSM • Grout Injection)
When Voids Exist Behind the Bulkhead
Voids caused by soil washout, tidal action, erosion, or poor compaction are best addressed with slurry injection because it:
- Completely fills hidden voids
- Bonds to both soil and structural surfaces
- Stops water migration and prevents future washout
When the Bulkhead is Moving, Rotating, Bowing, or Settling
Pressurized grout provides structural soil improvement by:
Â
- Stabilizing the soil mass
- Increasing bearing capacity beneath and behind the wall
- Densifying loose ground to reduce lateral pressure
When a Watertight Seal is Required
Cementitious slurry and microfine grouts are effective for:
Â
- Blocking seepage pathways
- Reducing hydraulic pressure acting on the bulkhead
- Injecting into cracks, joints, and seams for durable waterproofing
When Access for Traditional Backfill is Limited
If excavation is impossible or the backside of the bulkhead is inaccessible, slurry injection becomes the only practical solution.
When Traditional Backfill Would Add Excess Lateral Load
Wet soils impose significant lateral pressure. Grout—especially lean slurry or CLSM—adds less load and eliminates problems caused by poorly compacted fill.
Types of Pressurized Slurry Used
1. CLSM (flowable fill controlled low-strength material)
- Self-leveling
- Non-shrink
- Requires no compaction
- Excellent for large voids
2. Microfine Cement Grout
- Penetrates fine or dense soils
- Ideal for stabilizing sand and silt
3. Chemical Grouts (Hydrophobic Custom Mix)
- Designed for active water leaks
- Creates a permanent barrier
4. Soil-Cement Slurry
- Strengthens and separates soil from bulkhead
- Suitable for deeper stabilization zones
Recommendation
For Stabilization, Void Filling, and Erosion behind bulkheads
Using pressure injected custom cement based mixture to seal area behind the bulkheads
For Long-Term Drainage and Hydrostatic Pressure Reduction
Custom mixed material to fill erosion compromised areas underneath sidewalk caps at waterfront areas and behind bulkheads
For the Best Overall Performance
Remove existing concrete cap, to completely install the custom mixed curtain-to stabilize soil and manage water movement and reinstall new concrete waterfront cap
