Frequently Asked Questions (FAQs)

When performance cannot be compromised, your choice of material supplier is as critical as the material itself. We provide more than just a product; we deliver a technical partnership.

How long do fish pond liners last?

Quality liners can last 20-50+ years with proper installation. EPDM rubber liners have been proven to last over 30 years, while RPE liners are rated for 20-40 years. Budget options like PVC typically last 10-15 years. Longevity depends on UV exposure, underlayment protection, and maintenance.

Which liner material is safest for fish?

EPDM rubber, RPE, and LLDPE/LDPE are all completely safe for fish and aquatic life. Avoid PVC liners if possible, as they may contain trace amounts of arsenic and other chemicals from plasticizers that can leach into water over time. Always choose liners specifically designed for ponds, never use rubber roofing material.

What thickness should I choose?

For EPDM liners, 45 mil is standard and recommended for most applications. RPE liners are typically 30-36 mil due to their reinforced construction. LLDPE ranges from 17-20 mil, while PVC is usually 12-20 mil. Thicker isn’t always better; reinforced materials like RPE offer superior strength at lower thickness. Consider your specific application and traffic around the pond.

Do I need underlayment beneath my liner?

EPDM rubber liners require underlayment for warranty coverage, as they’re more susceptible to punctures. RPE liners don’t require underlayment on smooth surfaces like sand or clay. However, underlayment is always recommended for maximum protection from roots, rocks, and sharp objects, significantly extending liner life.

Can I repair a punctured liner?

Yes, most liners can be repaired. EPDM and RPE liners can be patched using special repair kits with adhesive patches. Clean and dry the damaged area thoroughly, apply primer if included, then press the patch firmly over the tear or puncture. Some materials can also be heat-welded for permanent repairs.

How do I prepare the pond base?

Remove all sharp objects, roots, and rocks from the excavation. Create a smooth base using 2-3 inches of sand or soft clay. Install geotextile underlayment if required. Ensure proper shelf levels and gradual slopes. The smoother and more protective the base, the longer your liner will last and the better it will perform.
