Custom Geomembrane Fabrication for Complex Projects

Complex specs. Fast turnaround. Field-ready fabrication.

That is where we do our best work. If your project has unusual dimensions, specific material requirements, or a timeline that leaves no room for back-and-forth, you are in the right place. We custom fabricate geomembranes, liners, and containment systems across secondary containment, erosion control, stormwater management, and specialty applications. With three fabrication locations across the U.S., we can help get your order built and to your jobsite quickly.

Six custom panels. Five field welds. One day on site.

Pennsylvania Well-Pad Containment System

When standard sizes, simple specs, or off-the-shelf products are not enough, Inland helps turn complex project requirements into field-ready fabricated solutions.

Challenge: The site had a non-standard perimeter berm configuration and no pre-existing design details.

Inland Solution: Our team reviewed the site information, developed a custom panel layout, and fabricated six 60XGL geomembrane panels sized for the project.

Field Result: The system was installed in one day with a six-person crew and only five field welds.

Why It Mattered: The fabricated layout reduced field work, eliminated unnecessary material waste, and helped the crew complete the installation before summer heat became a greater jobsite safety concern. This is where factory fabrication makes a measurable difference: fewer field seams, less wasted material, faster installation, and a layout built around the actual site.

What Our Fabrication Capacity Means for Your Project

Every custom order is fabricated in a controlled factory environment with documented QA/QC procedures. Your product is built, checked, and prepared before it ships. That can mean less field welding, fewer on-site variables, and a more efficient installation for your crew.

Material Guidance

We help match HDPE, LLDPE, CWPE, RPE, RPP, XR-series, and non-woven geotextiles to the application based on exposure, installation method, and expected service life.

Lead Time

Custom does not have to mean slow. Share your timeline, delivery location, material requirements, and project conditions, and we will help you understand what is workable.

Layout Planning

Send us your dimensions, drawings, site details, or project requirements. Our team can turn that information into a practical panel layout built around field conditions and delivery needs.

Factory Fabrication

Your panels are fabricated in a controlled factory environment before they ship. That helps reduce unnecessary field welding, material handling issues, and installation complexity on site.

Capacity is not just about square footage. It is about helping your project move from spec to installation with fewer field variables, better planning, and a fabricated system built around real jobsite conditions.

Common Applications for Custom Fabrication

The project drives the spec. If your application is not listed, tell us what you are working on. Chances are, we have fabricated something similar.

Secondary Containment Systems

Pit liners, tank liners, berm systems, and chemical storage containment have to fit the footprint, hold the required volume, and install without creating a field fabrication problem. Inland fabricates to exact dimensions using HDPE, LLDPE, CWPE, and other materials matched to your application, exposure, and chemical compatibility requirements.

Pond & Water Management Liners

Stormwater retention, detention, wastewater ponds, and impoundments often depend on panel layout, seam planning, and site-specific dimensions. Inland can fabricate one-piece or large-panel liner systems to help reduce field seams, simplify installation, and support a cleaner jobsite process.

Erosion & Slope Control

Channel lining, slope protection, embankment stabilization, and other erosion-control applications often depend on site conditions, hydraulic exposure, installation method, and project requirements. Inland can help configure geocell, geogrid, and ITL RCR® solutions around the conditions your team needs to manage.

Specialty Applications

Floating covers, above-ground storage systems, insulated covers, custom covers, and turnkey containment systems do not always fit into a standard product category. If you do not see what you need here, tell us what you are working on. Chances are, we have fabricated something similar.
