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.
Groundwater remediation challenges often extend beyond treatment alone. Depth, geology, access constraints, and ongoing site operations can limit the feasibility of conventional trenching or excavation approaches.
GeoSierra Trenchless PRBs help project teams overcome these constraints by enabling targeted, in situ treatment with minimal disruption. Controlled emplacement and advanced monitoring techniques support predictable barrier performance, while trenchless installation reduces waste, limits surface impact, and supports long-term remediation goals.
