Utility Trench Breakers
What are Utility Trench Breakers?
Utility trench breakers are underground barriers installed along utility corridors to block groundwater flow, prevent erosion, and protect pipelines from washouts. Using trenchless polymer injection, trench breakers are formed quickly and effectively, providing a durable alternative to concrete or sandbag systems.
Problems Solved
- Groundwater infiltration causing trench erosion
- Washouts undermining pipelines and conduits
- Soil instability in backfill around buried utilities
- Maintenance costs from failed concrete or sandbag breakers
- Delays from traditional breaker construction methods
Types of Polymers Used
High-Density Polyurethane Foams
- Expands to densify and stabilize loose backfill soils
- Provides lightweight reinforcement without added soil pressure
- Cures rapidly to minimize operational disruption
Structural Polyurethane Resins
- Creates rigid reinforcement zones behind walls and utilities
- Transfers structural loads to stable ground layers
- Extends service life of supported structures
Hydro-Insensitive Polymers
- Expands and cures in wet or groundwater conditions
- Seals voids and prevents erosion in saturated soils
- Provides long-term durability in challenging sites
Benefits of Utility Trench Breakers
Utility trench breakers with polymer injection protect underground utilities by blocking water flow and preventing erosion. These trenchless solutions are faster, more reliable, and longer lasting than conventional methods.
Durable Barriers to Protect Pipelines and Corridors
- Blocks groundwater migration in utility corridors
- Prevents erosion and washouts in trench backfill
- Provides durable trenchless barriers without concrete
- Reduces long-term repair and maintenance costs
