Grout Curtain Barrier Systems
What are Grout Curtain Barrier Systems?
Grout curtain barrier systems are underground walls formed by injecting grout into soils to create a continuous, low-permeability barrier. This trenchless method blocks groundwater migration, controls seepage, and reinforces surrounding soils to protect infrastructure from water-related damage.
Problems They Solve
- Groundwater infiltration threatening below-grade structures
- Seepage through embankments, levees, or dams
- Erosion and piping caused by uncontrolled water flow
- Hydrostatic pressure compromising retaining walls
- Soil instability around excavations and utility corridors
Types of Polymers Used
High-Density Polyurethane Foams
- Expands to fill voids and strengthen soils
- Creates lightweight, impermeable barriers
- Reduces water migration behind structures
Structural Polyurethane Resins
- Forms rigid underground walls that block seepage
- Enhances load-bearing capacity of surrounding soils
- Provides long-term durability in saturated zones
Hydro-Insensitive Polymers
- Expands and cures under wet or flowing conditions
- Effective for groundwater control in active environments
- Maintains impermeability over decades of service
Benefits of Grout Curtain Barrier Systems
Grout curtain barrier systems provide long-term groundwater control by creating impermeable underground walls. This trenchless solution protects infrastructure from erosion, seepage, and structural failure while minimizing surface disruption.
Reliable Seepage Control Without Excavation
- Blocks groundwater movement and seepage pathways
- Creates continuous underground barriers without excavation
- Stabilizes soils and reduces hydrostatic pressure
- Extends the service life of dams, levees, and buried structures
Key Applications
Dams & Levees
Stops hydrostatic pressure and stabilizes backfill soils
Tunnels & Underground Facilities
Protects liners and walls from groundwater intrusion
Retaining Walls
Stops hydrostatic pressure and stabilizes backfill soils
Culverts & Stormwater Systems
Restores watertight conditions in buried structures
Utility Corridors
Blocks groundwater migration around underground utilities
Embankments & Slopes
Controls seepage that leads to erosion and slope instability
Industries & Applications
Grout curtain barrier systems are used across industries where groundwater control and seepage prevention are critical. From transportation corridors to water management structures, these barriers provide long-lasting protection against erosion and water intrusion.
