Geotextile Liner Installation

Geotextile Liner Installation

Plastic Fusion Fabricators is a geotextile installation contractor for environmental, civil, and industrial containment projects. We install woven and nonwoven geotextiles as part of complete lined systems — the separation, filtration, and cushion layers that protect geomembrane liners and keep containment systems performing. As a containment contractor that installs the full geosynthetic stack, we deploy geotextile where it does its critical jobs: protecting the liner from puncture, separating soil layers, and filtering drainage.

Geotextile is a permeable fabric, not a barrier — and in a lined system that distinction is the point. A nonwoven geotextile placed under or over a geomembrane is the cushion that protects the barrier from puncture by the subgrade below or the cover stone above. Woven geotextiles separate and reinforce soil layers. In drainage applications, geotextile filters water while holding back soil. Each function protects the system, and each depends on correct installation — proper overlaps, seams, and placement that a product supplier can’t provide and a road crew doesn’t specialize in.

Plastic Fusion installs geotextile as part of lined containment, with 40+ years of liner experience across 24 states. When the same contractor installs the geotextile and the geomembrane, the cushion and the barrier are placed to work together.

Geotextile Functions in Containment

• Cushion and protection — nonwoven geotextile protecting geomembrane liners from puncture by subgrade or cover material
• Separation — keeping aggregate, soil, and drainage layers from intermixing
• Filtration — allowing water to pass while retaining soil particles in drainage systems
• Reinforcement — adding tensile strength to soils and subgrades
• Drainage support — working within leachate and stormwater collection systems

Geotextile Applications

• Cushion layers protecting geomembrane in landfill and pond liner systems
• Separation layers in containment cell construction
• Filtration in leachate and drainage collection
• Slope and subgrade reinforcement in lined systems
• Erosion control and shoreline protection
• Industrial and civil containment projects

How Geotextile Is Installed in Lined Systems

• Surface preparation — the subgrade or liner surface is prepared and inspected
• Layout and overlap — geotextile is rolled out with specified overlaps, oriented to its function (filtration, separation, or cushion)
• Seaming — overlaps are sewn or thermally bonded as the specification requires
• Placement over or under liners — when installed with a geomembrane, the geotextile is placed and secured without puncturing the barrier
• Cover placement — protected from equipment damage, with controlled access during cover or aggregate placement

Geotextile Installation FAQs

What is geotextile and what does it do?

Geotextile is a permeable fabric used with soil to separate, filter, protect, reinforce, or drain. It comes in woven forms (for separation and reinforcement) and nonwoven forms (for filtration and cushion/protection). In containment systems, its most important role is protecting the geomembrane liner: a nonwoven geotextile cushion placed under or over the barrier prevents puncture from the subgrade or cover material. Unlike a geomembrane, geotextile is not a barrier — it’s the fabric that protects and supports the barrier.

What is the difference between geotextile and geomembrane?

A geomembrane is an impermeable barrier — typically HDPE — that stops liquid from passing through; it’s what actually contains leachate or process fluid. A geotextile is a permeable fabric that lets water through while serving functions like separation, filtration, and cushion. In a lined system they work together: the geotextile protects and supports the geomembrane, and the geomembrane provides the containment. Plastic Fusion installs both as a single-source contractor.

Why does a geomembrane liner need a geotextile cushion?

Geomembranes can be punctured by sharp subgrade material below or by the stone and cover placed above them. A nonwoven geotextile cushion absorbs and distributes those point loads, protecting the barrier from puncture that would create a leak. On many containment projects the geotextile cushion is what gives the liner its long service life — which is why correct cushion selection and installation matters as much as the liner itself.

Do you install geotextile with the geomembrane liner?

Yes. We install geotextile and geomembrane as a single-source contractor. That coordination matters: the cushion geotextile has to be placed and secured to protect the barrier, and when one contractor installs both, the layers are sequenced and detailed to work together — with one point of accountability for the lined system.
