What Sets AST’s Bedrock Injection System Apart
AST’s custom bedrock injection platform is unmatched in the in-situ remediation industry. Developed in-house to meet the demands of difficult geology and legacy contamination, the system offers:
- Dual-controlled straddle packers with isolated injection zones as narrow as 18 inches
- Unconfined inflation pressures up to 2,250 psi for tight seal integrity
- High-volume injection capability (45–250 GPM) at pressures up to 2,000 psi
- Targeted emplacement into fractures, bedding planes, and fault zones—regardless of transmissivity
- Compatibility with slurries like BOS 100®, BOS 200®, BOS 200+®,and CAT 100® and soluble reagents
This level of control allows AST to deliver reagents where they’re actually needed, not just where the path of least resistance goes.
Why Our Approach Works — When Others Don’t
Contaminated bedrock sites often stall projects and frustrate stakeholders. AST’s unique combination of high-performance hardware, expert field execution, and adaptive injection design is changing that. Our clients choose AST because we offer:
- Precision: Narrow injection intervals and high-pressure sealing ensure targeted delivery
- Versatility: Effective in low-K and high-K zones, across varied rock types
- Proven Success: Used on complex sites where remediation was previously considered non-feasible
- Regulatory Confidence: Comprehensive methodology and data support compliance and site closure
- Experienced Team: Our injection crews are trained specifically for bedrock remediation
Cleanup Is Possible—Even in Challenging Bedrock
Whether the underlying geology is comprised of fractured shale, weathered sandstone, faulted and/or karstic carbonate systems, or igneous/metamorphic regimes, AST’s bedrock injection solutions are helping stakeholders across the country move legacy sites toward closure. If you’re dealing with persistent bedrock contamination, we’ll bring the tools, team, and technical strategy to solve it.
