Landfill Cell Construction for Waste Containment
On-site landfill cells are a proven solution for managing continuous industrial waste streams. AST specializes in constructing engineered containment systems using industry-standard materials and proven sequencing practices. Typical cell construction includes:
- Structural fill for subgrade stabilization
- Low-permeability clay liners
- Geosynthetic clay liners (GCL)
- High-Density Polyethylene (HDPE) geomembranes
- Geocomposite drainage layers
- Protective sand or soil cover layers
Proper coordination of liner installation and earthwork ensures long-term system integrity and regulatory compliance. AST has constructed several multi-layered landfill cells, including highly regulated designs for the pulp and paper industry.
Closure Systems for Inactive and Unpermitted Sites
When landfill cells reach capacity or when legacy disposal areas require remediation, closure becomes critical. AST installs engineered capping systems to reduce infiltration, prevent leachate generation, and protect groundwater. Our closure systems are built using many of the same components used in new landfill construction, tailored to the specific conditions of each site.
AST has installed multiple landfill closure systems, including:
- Permitted municipal landfill closures
- Hazardous waste dump site containment
- Industrial facility legacy site caps
These projects help clients reduce long-term liability and maintain compliance with federal and state closure regulations.
Industry-Leading Earthwork and Material Handling
AST’s experience in landfill construction is backed by extensive material movement capabilities. We have excavated, transported, and placed large quantities of soil and waste across a broad range of landfill projects. Our in-house expertise, fleet, and project management systems allow for safe, efficient, and precise execution on projects of any scale.
