Geomembrane and HDPE Liner Repair

Geomembrane & HDPE Liner Repair

Plastic Fusion Fabricators provides geomembrane and HDPE liner repair for ponds, lagoons, landfills, secondary containment, and industrial sites nationwide. When a liner tears, punctures, leaks, or a seam fails, the barrier is compromised — and every day it stays that way is lost containment, regulatory exposure, and risk to groundwater. We locate the failure, repair it by fusion and extrusion welding back to the liner’s original integrity, and test the repair to confirm it holds. As the fusion welders who install these systems, we repair them the right way — not with a temporary patch, but with a tested, permanent weld.

A geomembrane liner is a fusion-welded barrier, and a proper repair restores it to that same fused, continuous condition. A failed seam gets re-welded. A puncture or tear gets a fusion-welded patch of the same material. A leak gets located, repaired, and re-tested. The difference between a repair that lasts and one that fails again is whether it’s done with the same welding expertise and testing discipline as the original installation. That’s what separates a liner contractor from a patch-job.

With 40+ years installing and repairing HDPE and geomembrane systems across 24 states, Plastic Fusion brings certified welders and documented testing to every repair — on liners we installed and liners we didn’t.

Liner Repairs We Perform

• Seam repairs — re-welding failed or separating fusion seams
• Puncture and tear repairs — fusion-welded patches in HDPE, LLDPE, and RPP
• Leak location and repair — finding and sealing leaks in exposed and covered liners

• Mining containment and leach pad repair
• Agricultural and water storage liner repair

Why a Failing Liner Can’t Wait

A compromised liner is an active problem. A leak means containment fluid is escaping — lost product, contaminated soil or groundwater, and potential regulatory violation. A failed cap lets water in. A torn pond liner loses water and undermines the system. The longer a failure goes unrepaired, the more it costs — in lost containment, in environmental exposure, and in the larger repair the damage becomes. Fast, properly welded and tested repair protects the system and limits the liability.

Geomembrane & HDPE Liner Repair FAQs

How are HDPE and geomembrane liners repaired?

HDPE and geomembrane liners are repaired by fusion and extrusion welding — the same welding methods used to install them. A failed seam is re-welded; a puncture or tear is repaired with a fusion-welded patch of the same material; a leak is located, sealed, and re-tested. Because the repair is welded into the existing liner, it restores the barrier to a continuous, tested condition rather than relying on adhesives or temporary patches. The repair is then tested to confirm it’s leak-tight.

Can you repair a liner you didn’t install?

Yes. We repair geomembrane and HDPE liners regardless of who installed them. Our fusion welding expertise applies to any HDPE, LLDPE, or RPP liner, and our crews locate the failure, repair it to original integrity, and test the repair. Whether it’s a liner we installed or one installed by others, the repair is done to the same standard as new work.

Do you offer emergency liner repair?

A failing liner is an active containment problem, and we mobilize for urgent repairs. The priority is locating and sealing the failure before it causes further loss or environmental exposure. With crews experienced across many sites and the ability to mobilize nationwide, we respond to repair needs on ponds, lagoons, landfills, and containment systems where containment can’t wait.

How do you find leaks in a liner?

Leak location depends on whether the liner is exposed or covered. Exposed liners can be inspected visually and tested by section. Covered liners may require leak-location survey methods to pinpoint the failure before excavating to repair it. Locating the actual point of failure — rather than guessing — is what makes a repair effective, and our installation experience helps us identify where and why liners fail.

Is a welded repair as strong as the original liner?

A properly executed fusion or extrusion weld restores the liner to a continuous barrier as strong as the surrounding material. That’s the advantage of polyethylene geomembrane: it’s welded, not glued, so a welded repair becomes part of the liner itself rather than a separate patch that can peel or fail. We test repairs to confirm they meet the same leak-tightness standard as the original installation.
