AST’s custom bedrock injection system is unique in the remediation industry. It combines high-capacity pumping and a custom set of straddle packers to isolate discrete geologic features and contaminant mass. The custom straddle packers’ features include unconfined inflation pressures up to 2,250 psi, independent control of the upper and lower packers, and targeted injection intervals as narrow as 18 inches. Injection flow rates of 45 to 250 gallons per minute at pressures of up to 2,000 psi allow AST to emplace injection fluids and slurries within low and highly transmissive bedrock features including bedding planes, fractures, and across fault systems. The combination of this unique equipment and AST’s experienced injection team lead to more effective and efficient cleanup of contaminated bedrock sites.
