HDPE Liner Installation Contractor

HDPE Liner Installation Contractor

Plastic Fusion Fabricators is an HDPE liner installation contractor — an HDPE lining specialist installing high-density polyethylene geomembrane for ponds, lagoons, landfills, secondary containment, and industrial sites nationwide. HDPE is the workhorse of environmental containment: the most chemically resistant, durable, and widely specified geomembrane, and the barrier most projects are built on. With 40+ years of HDPE experience and active projects across 24 states, PFF installs, fusion-welds, tests, and documents HDPE liner systems built to last.

HDPE (high-density polyethylene) is the geomembrane of choice for most containment because of what the material does: it resists an enormous range of chemicals, it won’t degrade in UV exposure, it holds up against the leachate and process fluids that destroy other materials, and its fusion-welded seams create a continuous, monolithic barrier as strong as the sheet itself. Whether it’s a 40-mil pond liner or a 100-mil landfill barrier, the performance comes from correct installation — fusion welds that are tested and documented, penetrations that are sealed, and a system that’s installed to specification.

Plastic Fusion has installed hundreds of millions of square feet of HDPE and geomembrane over four decades. As an HDPE lining contractor, we self-perform the work — our certified welders fuse and test every seam, and we document the CQA the project requires.

HDPE Liner Applications

• Pond, lagoon, and reservoir liners
• Landfill liner and cap systems
• Secondary containment for tanks and process areas
• Industrial process and wastewater containment
• Mining containment and leach pads
• Agricultural and water storage containment

Why HDPE for Liner Systems

• Chemical resistance — withstands a broad range of acids, bases, and hydrocarbons that degrade other liners
• UV and weathering resistance — performs in exposed applications without breaking down
• Fusion-welded seams — hot-wedge and extrusion welding create continuous, leak-tested joints
• Durability — resists puncture, abrasion, and stress cracking over a long service life
• Range of thicknesses — from lighter pond liners to heavy 60-mil, 80-mil, and 100-mil containment barriers
• Proven standard — the most widely specified geomembrane for environmental containment

Why Owners and Engineers Choose Plastic Fusion

• 40+ years installing HDPE liner and containment systems
• HDPE lining contractor that self-performs — certified welders, not subcontracted crews
• Hot-wedge and extrusion fusion welding with documented seam testing
• Custom HDPE fabrication — boots, penetrations, and sump liners built to spec
• Documented CQA for compliance and owner records
• Hundreds of millions of square feet of HDPE and geomembrane installed
• Active projects across 24 states with nationwide mobilization
• Full geomembrane capability across all liner materials and geosynthetic systems

How HDPE Liner Is Installed

• Subgrade preparation — graded, compacted, and cleared of anything that could puncture the liner
• Panel deployment — HDPE panels deployed and positioned, with custom fabrication to minimize field seams
• Fusion welding — seams joined by hot-wedge (dual-track) and extrusion welding
• Seam testing — non-destructive air-pressure and vacuum testing plus destructive peel/shear sampling, all documented
• Penetrations and anchoring — pipe boots and details sealed and tested, perimeter anchored in trenches
• CQA documentation — complete installation records for the owner and regulators

Industries Served

Plastic Fusion installs HDPE liner for landfill and solid waste operators, mining and mineral processing, municipal and industrial water and wastewater utilities, agricultural operations, and the environmental engineering and construction firms managing lined containment nationwide.

HDPE Liner Installation FAQs

What is an HDPE liner?

An HDPE liner is an impermeable geomembrane barrier made of high-density polyethylene, used to contain liquids and protect soil and groundwater. It’s the most widely specified geomembrane for environmental containment because of its chemical resistance, durability, UV stability, and fusion-weldable seams. HDPE liners are installed in ponds, lagoons, landfills, secondary containment, and industrial sites, in thicknesses typically ranging from 40-mil to 100-mil depending on the application.

What does an HDPE lining contractor do?

An HDPE lining contractor installs HDPE geomembrane liner systems — preparing the subgrade, deploying and fusion-welding the panels, testing every seam, sealing penetrations, and documenting the installation through Construction Quality Assurance. The contractor’s welders, testing rigor, and field experience determine whether the liner performs. Plastic Fusion is an HDPE lining contractor that self-performs the work with certified welders and documented QA/QC, with 40+ years and hundreds of millions of square feet installed.

What HDPE liner thicknesses do you install?

We install the full range of HDPE geomembrane thicknesses, from lighter liners for ponds and water storage to heavy 60-mil, 80-mil, and 100-mil barriers for landfills, chemical containment, and demanding applications. The right thickness depends on the chemical exposure, mechanical demands, and regulatory requirements of the project, and we help specify it to the application.

Is HDPE the same as geomembrane?

HDPE is a type of geomembrane — the most common one. “Geomembrane” is the general category of impermeable synthetic barriers, which also includes LLDPE and reinforced polypropylene (RPP). HDPE is specified for most containment because of its chemical resistance and durability, but the right material depends on the application — LLDPE for more flexibility and conformance, RPP for certain exposed covers. Plastic Fusion installs all geomembrane materials and helps specify the right one.

Do you repair HDPE liners as well as install them?

Yes. In addition to new installation, we repair HDPE liners — heat welding, patching, and testing to fix tears, punctures, and failed seams. Because HDPE is fusion-welded, repairs restore the barrier to a continuous, tested condition. Our crews handle both new HDPE liner installation and repair of existing systems.
