KOE Pond Liners - Features, Benefits and Installation
KOE pond liners from KÖPP are advanced geomembrane solutions engineered for long-term water containment. Made from flexibilized polypropylene (FPP), KOE liners combine strength, flexibility and chemical resistance - ideal properties for reliable pond lining.
This article provides an overview of KOE pond liners, their key properties, installation methods and benefits over other liner materials.
Introduction to KOE Pond Liners
KOE refers to the brand of pond lining products manufactured by KÖPP, a renowned German geosynthetics company. KOE stands for Kombinierte-Oberflächenentwässerung which translates to “combined surface drainage”.
The KOE liners are made from flexibilized polypropylene (FPP) which imparts an optimal balance of properties:
- High strength and puncture resistance
- Flexibility for conformation into contours
- Lightweight for easy installation
- Chemical and weathering resistance
- Impermeability for water containment
- Can be welded for continuous seams
With these well-rounded material properties, KOE is an advanced geomembrane ideal for pond lining applications.
Thickness and Supply Options
KOE pond liners are produced in thicknesses from 1mm to 2mm.
The standard thickness used for most pond lining applications is 1mm, which provides adequate puncture resistance and reliability.
The liners are supplied in roll form, with widths up to 16m available for large projects. The KOE material is green in color for easy visual inspection.
Benefits of KOE Pond Liners
Some of the key advantages of KOE FPP liners over other materials:
- Flexibility – Allows easy conformation into curved pond walls and floors.
- Lightweight – At around 1kg per sqm, KOE is lighter than HDPE for faster installation.
- Weathering Resistance – Withstands UV exposure, humidity, temperature fluctuations from -50°C to 90°C.
- Chemical Resistance – Inert to acids, alkalis, salts and common chemicals. Safe for aquatic life.
- Weldability – Strong, continuous seams can be formed using thermal welding.
- Life Span – With material durability, KOE liners provide decades of reliable service life.
With these well-rounded benefits, KOE offers performance and installation advantages over other pond liners.
Pond Liner Installation
Proper steps for installing KOE pond liners include:
- Grading and compacting the base to smooth finish
- Rolling out liner sections from one end with overlap for seams
- Forming continuous seams by wedge welding overlaps
- Fixing liner edges into perimeter anchor trench
- Sealing inlets, outlets and penetrations using membrane boots
- Covering liner with geotextile cushion and ballast layer
KÖPP provides specialized welding equipment and certified installers to ensure correct liner deployment.
Pond Types Suited for KOE Liners
With their advanced material properties, KOE liners are ideal for:
- Decorative ponds – Flexibility allows creative shaping
- Recreational ponds – Durable for public access areas
- Golf course water hazards – Chemical resistance suits fertilizer exposure
- Aquaculture ponds – Inert material safe for aquatic life
- Agricultural ponds – Withstands drying and re-watering cycles
- Stormwater ponds – Handles intermittent water levels
KOE liners from KÖPP provide long-term performance across any type of artificial pond.
Conclusion
KOE flexibilized polypropylene geomembranes from KÖPP offer an advanced liner solution combining strength, flexibility and longevity. With performance benefits over other pond liners, KOE allows fast, easy installation with continuous welded seams. For durable and reliable containment of high-value water resources, KOE is an ideal pond lining solution.
