Excavation is a critical component of many environmental remediation strategies. AST Environmental leverages decades of experience to safely remove contaminated soils and waste, reducing immediate risks to human health and the environment. Whether used as a standalone action or as part of a larger remedial approach, excavation must be executed with precision, regulatory compliance, and a clear understanding of site-specific challenges.

Strategic Excavation as a Remedial Tool

Excavation is often the fastest and most direct method to eliminate environmental hazards from impacted sites. It frequently complements technologies like:

  • Off-site landfill disposal
  • In-situ chemical treatment or stabilization

Before disposal, soils may require pretreatment—biological, chemical, or thermal—depending on contaminant type and disposal criteria. AST is equipped to manage this full process efficiently and safely.

Proven Experience in Complex Excavation Projects

AST has removed and managed large quantities of contaminated soil and waste from sites across the U.S. and internationally. We handle projects of all sizes—from small-scale cleanups to massive industrial site remediations. Notable experience includes:

  • Small excavations (<100 CY) to massive operations (100,000+ CY)
  • Contaminant types: petroleum hydrocarbons, chlorinated solvents, PCBs, heavy metals
  • Sites ranging from rural properties to active industrial operations

Our team is equipped to execute high-risk excavations in sensitive environments—inside buildings, adjacent to structural foundations, near, above and below ground utilities, and in active waterways.

Advanced Excavation Capabilities

AST brings the equipment and know-how to manage technically challenging digs, including:

  • Shoring systems: Sheet piling and trench boxes for safe excavation in unstable soils
  • Dewatering: Physical and chemical methods to manage groundwater intrusion
  • Segregation and stockpiling: On-site handling of impacted and non-impacted material
  • Pretreatment: Field-scale contaminant reduction to meet disposal criteria
  • PPE Compliance: Level B and C personal protective equipment for worker safety in hazardous zones
