Excavation Trench Breakers
What are Excavation Trench Breakers?
Excavation trench breakers are underground barriers installed in utility trenches to block water flow, prevent erosion, and maintain soil stability. With trenchless polymer injection, trench breakers are constructed quickly and effectively, eliminating the need for concrete or sandbags.
Problems Solved
- Groundwater infiltration causing trench erosion
- Washouts undermining pipelines and conduits
- Soil instability around trench backfill
- Costly maintenance from failed trench breaker systems
- Inefficiencies of concrete or sandbag breaker installation
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 Excavation Trench Breakers
Excavation trench breakers with polymer injection provide watertight, long-lasting protection against groundwater infiltration and erosion. These trenchless solutions are faster and more reliable than traditional breaker methods.
Durable, Trenchless Barriers for Utility Protection
- Blocks groundwater movement in utility trenches
- Prevents erosion and soil washouts around pipelines
- Provides durable trenchless barriers without concrete
- Minimizes maintenance and long-term repair costs
