Tank Liner Installation & Repair Contractor

Tank Liner Installation & Repair Contractor

Plastic Fusion Fabricators is a tank liner installation contractor specializing in flexible geomembrane liners for commercial, custom, manure, agricultural, and industrial tanks. A tank liner is the impermeable HDPE, LLDPE, or RPP barrier installed inside or around a tank to contain its contents, protect the tank structure, and prevent leaks from reaching the soil and groundwater. We fabricate and install drop-in and fitted tank liners — and repair existing ones — for tanks of every size and service. With 40+ years of geomembrane fabrication and installation across 24 states, Plastic Fusion is the contractor to call when a tank has to hold what’s in it.

A tank liner does what the tank alone often can’t: it provides a continuous, chemically compatible, leak-proof barrier between the stored material and the tank wall. Whether you’re lining a new tank, retrofitting an old one that’s started to leak, or adding secondary containment, the liner has to fit the tank, resist the contents, and seal completely. That’s fabrication and installation work — and it’s what we do.

Tanks We Line

We line and repair the full range of tanks, with dedicated expertise for each:

• Commercial tanks — liners for commercial storage and process tanks: commercial tank liners
• Custom tanks — custom-fabricated liners for non-standard tanks and unique requirements: custom tank liners
• Manure tanks — liners for manure and agricultural waste storage tanks: manure tank liners

We also line agricultural and fertilizer tanks, wastewater and water tanks, and process tanks across industries — matching the liner material to the contents and the tank.

Tank Liner Repair

Tanks leak. Liners age, crack, and fail, and a tank that’s lost its liner is a containment risk. We repair and replace tank liners — patching, relining, or installing a new fitted liner — to restore the tank to reliable, leak-free service without the cost of replacing the tank itself.

Flexible Geomembrane Tank Liners

Our tank liners are flexible geomembrane — not rigid fiberglass, metal, or coating systems. That means a fitted or drop-in liner that conforms to the tank, seals continuously, and can be fabricated to almost any tank shape:

• HDPE (high-density polyethylene) — excellent chemical resistance and durability for a wide range of tank contents
• RPP (reinforced polypropylene) — flexible, highly chemical-resistant for aggressive chemicals, fertilizers, and fuels
• LLDPE — added flexibility to conform to tank geometry and detailing

We match the material to what the tank holds and fusion-weld or detail the liner to seal completely, including around fittings and penetrations.

Tank Liner Installation, Not Just Industrial Ponds

Tank lining is its own discipline — fitting a liner to a contained vessel rather than an open basin. If your project is an open pond, pit, or basin rather than a tank, our industrial liner installation covers that work. This page and its tank-specific pages are for lining and repairing tanks.

Tank Liner FAQs

What is a tank liner?

A tank liner is an impermeable barrier installed inside or around a tank to contain its contents and prevent leaks. Our tank liners are flexible HDPE, LLDPE, or RPP geomembrane — fabricated to fit the tank, fitted or dropped in, and sealed continuously. It’s the working barrier between what the tank holds and the tank wall, the ground, and the groundwater.

What is the best material for a tank liner?

It depends on what the tank holds. HDPE offers broad chemical resistance and durability for many tank contents; RPP is the choice for aggressive chemicals, fertilizers, and fuels; and LLDPE adds flexibility for complex tank geometry. We match the material to the contents and the tank. We install flexible geomembrane liners rather than rigid fiberglass, metal, or coating systems.

Do you repair existing tank liners?

Yes. We patch, reline, and replace failed or aging tank liners, restoring the tank to leak-free service without replacing the tank itself.

What types of tanks do you line?

Commercial, custom, manure, agricultural, fertilizer, wastewater, water, and industrial process tanks. We have dedicated pages for commercial, custom, and manure tank liners, and we line tanks across other industries as well.
