FAQ — DETAILED QUESTIONS & ANSWERS
CAN I INSTALL A POND LINER MYSELF?
PVC and LDPE can be installed relatively easily using basic tools such as a knife and hot air welder.
EPDM requires special adhesive and often professional installation for durable seams.
Astryn FPP liner requires specific welding or bonding techniques due to its material structure and high chemical resistance.
Self-installation means you are responsible for accurate measurements and precise installation.
Mistakes can lead to leaks, damage or reduced lifespan.
For large or complex ponds, professional advice is strongly recommended.
HOW DO I CALCULATE THE REQUIRED LINER?
Measure length, width and depth of your pond or basin.
Add at least ±20 cm margin for overlap and finishing.
A common formula is: (Length + 2×depth + 0.2 m) × (Width + 2×depth + 0.2 m).
Always double-check before ordering.
Consider corners and obstacles.
For complex shapes, it is best to sketch the pond or consult a specialist.
This prevents shortages or unnecessary waste.
WHICH LINER IS BEST FOR KOI PONDS?
For koi basins, EPDM, 4EverFlex and Astryn are excellent options.
They are flexible, root- and UV-resistant and safe for fish.
PVC is less recommended for long-term use in fish ponds.
Choose a liner that does not release harmful substances.
Consider lifespan, thickness and installation method.
EPDM and 4EverFlex are most commonly used for professional koi ponds due to durability and safety.
IS POND LINER WELDABLE?
PVC, LDPE and Astryn can be thermally welded with the right equipment.
This creates strong and durable seams.
EPDM cannot be welded and must be joined using special adhesive.
Proper temperature, speed and pressure are crucial during welding.
Incorrect technique may lead to leaks and reduced lifespan.
IS THE LINER SAFE FOR DRINKING WATER?
Astryn FPP and high-quality EPDM variants are safe for drinking water and fish ponds as they contain no plasticizers or harmful substances.
Always check product specifications and certifications.
Consult a specialist if in doubt.
Proper installation and maintenance ensure long-term water safety.
HOW DO I MAINTAIN MY POND LINER?
Regular maintenance extends the lifespan of your liner.
Remove leaves and debris from the surface.
Inspect seams annually for small damages.
Avoid sharp objects and aggressive chemicals.
Small repairs can be made using repair kits or professional welding.
Good maintenance prevents leaks and preserves water quality.
CAN I USE THE LINER FOR RAINWATER TANKS?
Yes, EPDM, LDPE and Astryn are suitable for rainwater basins.
They are chemically resistant and safe for water storage.
Ensure proper overlap and sealing of seams.
A watertight connection prevents leakage.
For large systems, professional advice is recommended.
