Excavation Support
What is Excavation Support?
Excavation support stabilizes surrounding soils during trenching, foundation work, or underground construction to prevent collapse and ensure worker safety. With trenchless polymer injection, soils are reinforced without heavy shoring or disruptive methods, keeping projects safe and efficient.
Problems Solved
- Soil collapse risks during trenching or excavation
- Instability around utility and pipeline corridors
- Weak soils unable to support open cuts safely
- Groundwater infiltration weakening excavation walls
- Delays and hazards from conventional shoring requirements
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 Support
Excavation support with polymer injection prevents collapse and groundwater intrusion, enabling safe and efficient trenching or foundation work. These solutions minimize risk, reduce downtime, and protect workers and infrastructure.
Safer Excavations With Trenchless Soil Reinforcement
- Reinforces soils to prevent collapse in excavations
