Subsidence Mitigation
What is Subsidence Mitigation?
Subsidence mitigation restores stability to areas affected by downward ground movement caused by weak soils, voids, or groundwater issues. Through trenchless polymer injection, soils are strengthened, cavities are filled, and settlement is corrected to protect structures and infrastructure.
Problems Solved
- Ground subsidence undermining roads, buildings, or utilities
- Voids forming from erosion or poor soil compaction
- Settlement causing cracking or misalignment in structures
- Soil weakening from groundwater infiltration or drought cycles
- High costs and disruption from excavation-based repairs
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 Subsidence Mitigation
Subsidence mitigation with polymer injection stabilizes soils and corrects settlement without excavation. These solutions prevent further ground movement, restore structural alignment, and extend the life of infrastructure.
Protect Infrastructure From Ground Movement
- Stops subsidence and soil loss beneath assets
- Restores support for foundations, pavements, and utilities
- Provides trenchless stabilization with minimal disruption
- Extends infrastructure service life and reduces repair costs
