Engineered Containment System

LANDFILL LINER & CAPPING SYSTEM

Multi-layer geomembrane barrier system designed to prevent leachate migration, isolate waste mass, and ensure long-term environmental containment in compliance with regulatory standards.

Environmental Challenge

Preventing Subsurface Contamination

Municipal solid waste and hazardous landfills generate leachate containing dissolved contaminants that can migrate into soil and groundwater if not properly contained.

Engineered liner and capping systems create a low-permeability barrier with drainage and protection layers to ensure long-term hydraulic isolation.

The landfill liner system is engineered as a multi-barrier containment structure to prevent downward migration of contaminants.

The geomembrane functions as the primary hydraulic barrier, while the clay or GCL layer provides secondary redundancy.

Drainage layers manage leachate flow and reduce hydraulic head pressure on the liner interface.

Functional Mechanism

The geomembrane liner acts as a low-permeability barrier preventing downward migration of leachate under hydraulic gradient.

The drainage layer reduces hydraulic head pressure by facilitating controlled leachate collection and transfer toward sump systems.

The geotextile cushioning layer protects the geomembrane from puncture damage caused by waste mass or subgrade irregularities.

The compacted clay or geosynthetic clay liner (GCL) functions as a secondary barrier providing redundancy against leakage.

Proper seam welding and field integrity testing ensure continuous hydraulic containment across panel joints.

Final capping systems limit infiltration, control gas emissions, and stabilize the waste surface.

Design Considerations
