Landfill Liner Installation Contractor

Landfill Liner Installation Contractor

Plastic Fusion Fabricators is a landfill liner installation contractor delivering engineered HDPE and geomembrane liner systems for municipal solid waste, industrial, and hazardous waste landfills nationwide. We install the primary and composite liner systems, leachate collection components, and cell liners that keep landfills compliant with EPA and Subtitle D requirements — backed by certified welders, documented CQA, and 40+ years of environmental containment experience.

A landfill liner system is the engineered barrier that protects groundwater from leachate. Done right, it’s a multi-component system — geomembrane, geosynthetic clay liner (GCL), drainage, and protective layers — installed to exacting standards and tested for integrity before a single load of waste goes in. The liner is only as good as the installation: every seam, penetration, and anchor has to be welded and tested correctly, because a failure underground is nearly impossible to fix once the cell is filled. That’s why landfill owners and engineers hire experienced installation contractors, not just liner suppliers.

Plastic Fusion has installed liner systems across 24 states and hundreds of millions of square feet of geomembrane over four decades. We’re a contractor — we mobilize crews, weld and test the liner, document the QA/QC, and stand behind the installation.

Landfill Liner Systems We Install

• HDPE geomembrane liners — the primary barrier for landfill cells, 60-mil and heavier
• Composite liner systems — geomembrane over GCL or compacted clay for Subtitle D compliance
• Landfill cell liners — new cell construction and cell expansions
• Leachate collection liners — sumps, trenches, and collection layer components
• Secondary and double-liner systems — with leak detection for hazardous waste (Subtitle C) applications
• Landfill closure and capping — final cover systems over completed cells

EPA and Regulatory Compliance

Landfill liner systems are governed by federal and state environmental regulations, and proper installation is what makes a system compliant:

• RCRA Subtitle D — municipal solid waste landfill liner and leachate collection requirements
• RCRA Subtitle C — hazardous waste landfill double-liner and leak detection requirements
• EPA groundwater protection — liner systems engineered and installed to prevent leachate migration
• CQA (Construction Quality Assurance) — documented seam testing, destructive and non-destructive, with full records
• ASTM and GRI standards — material and installation conformance

Plastic Fusion installs to these standards and documents the CQA that regulators, engineers, and owners require.

Landfill Liner Installation FAQs

What is a landfill liner system?

A landfill liner system is the engineered barrier installed at the bottom and sides of a landfill cell to prevent leachate — the contaminated liquid that drains through waste — from reaching groundwater. Modern systems are typically composite: an HDPE geomembrane over a geosynthetic clay liner (GCL) or compacted clay, with a leachate collection layer above. Hazardous waste landfills require double-liner systems with leak detection between the layers. The system must be installed and tested to EPA and RCRA standards.

What makes a good landfill liner installation contractor?

The liner system’s performance depends entirely on installation quality — every seam must be welded correctly and tested, every penetration sealed, and the whole installation documented through Construction Quality Assurance (CQA). A good contractor brings certified welders, proven field experience across many sites, rigorous seam testing (both destructive and non-destructive), and complete documentation. Because a liner failure is nearly impossible to repair once a cell is filled, experience and QA/QC discipline are what separate qualified contractors from liner suppliers.

What liner materials are used in landfills?

The primary barrier is almost always HDPE geomembrane — typically 60-mil or heavier — chosen for its chemical resistance, durability, and weldability. It’s often paired with a geosynthetic clay liner (GCL) or compacted clay to form a composite system. Drainage geocomposites and protective geotextiles complete the system. HDPE is the industry standard for landfill liners because of its chemical resistance to leachate and its fused-seam integrity.

What standards govern landfill liner installation?

Landfill liners are governed by RCRA Subtitle D (municipal solid waste) and Subtitle C (hazardous waste), along with EPA groundwater protection requirements and state regulations. Installation conformance is documented through Construction Quality Assurance (CQA), with seam testing per ASTM and GRI standards. Plastic Fusion installs to these requirements and provides the CQA documentation that compliance demands.

Does Plastic Fusion install composite and double-liner systems?

Yes. We install composite liner systems (geomembrane over GCL or clay) for Subtitle D municipal landfills and double-liner systems with leak detection for Subtitle C hazardous waste applications. Our crews install the full system — barrier, drainage, and protective layers — with documented CQA on every component.
