The GeoSierra Trenchless Permeable Reactive Barrier (PRB) is a patented, field-proven solution for passive, long-term groundwater remediation in deep and complex environments. By enabling the installation of continuous subsurface treatment zones without open excavation, this approach supports remediation in urban settings, mixed plumes, and areas with limited access. Using controlled hydraulic inclusion propagation, GeoSierra PRBs form vertical permeable treatment barriers that intercept and treat contaminated groundwater while maintaining predictable performance across variable subsurface conditions.
Key Benefits
- Low site impact – No excavation, minimal disruption
- Built for complexity – Performs in mixed plumes and variable geology
- Proven performance – Controlled placement with verified results
- Broad treatment scope – Effective for VOCs, metals, PFAS, and more
- Long-term solution – Passive system designed for durability
