Pond Containment Systems
Protecting liner systems and supporting reliable liquid containment.
Geotextiles in Pond Containment Systems
Pond containment systems are used to store, collect or manage liquids in a controlled way. Whether used for stormwater retention, industrial water storage, wastewater treatment, agricultural ponds or environmental containment, the liner system must remain protected and functional throughout its service life.
Our needle-punched nonwoven geotextiles are used as protection layers in pond containment systems. Installed above, below or on both sides of a liner or geomembrane, the geotextile helps protect the barrier from puncture, abrasion and localised mechanical stress.
During installation and operation, pond liners can be exposed to rough subgrades, sharp stones, aggregate layers, settlement movements and changing water pressure. Without a suitable protection layer, these stresses can damage the liner and reduce the reliability of the containment system.
By acting as a cushioning and protective layer, our geotextiles help preserve liner integrity and contain the water. Depending on the project design, they can also contribute to separation, filtration and drainage around the pond structure.
Key Benefits
- Protects pond liners and geomembranes from puncture and abrasion
- Acts as a cushioning layer between the liner and rough or sharp surfaces
- Helps reduce localised stress on liquid containment systems
- Separates soil, aggregate and lining layers where required
- Supports filtration by retaining fine particles while allowing controlled water flow
- Contributes to drainage and reduced pressure build-up around the liner system
Example of a Layer Structure
In pond containment systems, nonwoven geotextiles are commonly installed directly next to the liner or geomembrane. Their exact position depends on the pond design, the type of liquid being contained and the protection requirements of the project.
- Contained liquid
The water, wastewater or process liquid stored or managed within the pond. - Upper protection layer
Where required, a nonwoven geotextile may be installed above the liner to protect it from cover materials, ballast or mechanical stress. - Liner or geomembrane
The primary containment barrier designed to prevent unwanted liquid migration into the surrounding soil. - Lower nonwoven geotextile protection layer
Installed beneath the liner to protect it from puncture, abrasion and localised stress caused by the prepared ground or underlying materials. - Prepared subgrade or foundation soil
The compacted and shaped base that supports the pond containment system.
