Liquefaction Mitigation
What is Liquefaction Mitigation?
Liquefaction mitigation is the process of strengthening soils to resist seismic loading, vibration, and dynamic stress. By injecting expanding polymers into loose or saturated soils, the method increases density, reduces pore water pressure, and improves ground stability during earthquakes or other dynamic events.
Problems It Solves
- Soil instability during seismic activity or heavy vibration
- Sudden settlement and loss of bearing capacity in saturated soils
- Damage to foundations, pavements, and underground structures
- Erosion and soil displacement caused by ground shaking
- Long-term risk of failure in critical infrastructure located in liquefaction zones
Types of Polymers Used
High-Density Polyurethane Foams
- Expands to densify loose or saturated soils
- Provides lightweight support without adding soil load
- Improves resilience to seismic stress and vibration
Structural Polyurethane Resins
- Forms rigid reinforcement in weak zones
- Transfers structural loads to more competent soils
- Extends long-term ground stability for critical assets
Hydro-Insensitive Polymers
- Expands and cures in wet or saturated conditions
- Reduces pore water pressure that triggers liquefaction
- Maintains performance in challenging seismic environments
Benefits of Liquefaction Mitigation
Liquefaction mitigation reduces the risk of catastrophic settlement during seismic events by improving soil density and stability. This trenchless solution protects foundations and critical infrastructure with minimal surface disruption.
Strengthened Soils for Safer Infrastructure
- Increases soil density and resistance to liquefaction
- Provides long-term seismic protection for infrastructure
- Non-destructive, trenchless installation method
- Reduces downtime and repair costs after seismic events
