Additional Information about HDRPE Pond Liner

Certification:

• Safe for fish, plants and aquatic wildlife, tested by independent laboratories under US environmental standards.

 

How to calculate the liner size:

Standard formula:

• Pond length + (2 × depth) + 2' = Liner length

• Pond width + (2 × depth) + 2' = Liner width

Practical example:

• Pond of 10' length, 6' width, 2.5' depth ? Needs 17' x 13' liner

 

Calculating pond volume:

Rectangular or square ponds:

•     Length × Width × Depth × 7.5 = Gallons of water

Round ponds:

•     Radius × Radius × 3.14 × 7.485 = Approximate gallons

Frequently Asked Questions (FAQs)

What type of material to choose: EPDM, HDRPE, LLDPE, RPE??

A common issue among those starting a pond project is:

"Which liner should I buy, EPDM or HDRPE, and what thickness?"

 

• AmericanTilapia Recommendation:  

Our pond liners are manufactured in industrial-grade HDRPE, with a real thickness of 40 mil (not inflated in mm like other suppliers).  

Additionally, they are certified safe for fish, free of toxins, and have built-in UV protection, ideal for outdoor ponds, aquaculture systems and long-term projects.  

Built to last, backed by integrity: At AmericanTilapia, we proudly offer high-performance materials you can trust. No shortcuts, no compromises just genuine durability that delivers on every promise.

 

 

How much pond liner do I need for my pond?

"How do I know what size I need for my pond?"

 

?? AmericanTilapia Tip:  

Use this proven formula:

- Pond length + (2 × depth) + 2 feet = liner length

- Pond width + (2 × depth) + 2 feet = liner width

 

We always recommend adding space for the "apron" and avoiding unnecessary seams, which are potential leak points.  

And if you need help, our team will advise you at no additional cost to help you choose the right size.

 

Can I connect two liners or extend an existing one?

"Can two liners be connected without leaks?"

 

• AmericanTilapia Solution:  

Yes, as long as you use professional repair kits or heat welding.  

However, we always recommend purchasing a single piece, custom-made if necessary.  

Avoiding seams is the best way to ensure 0 leaks in the future.

 

What to put under the pond liner?

One of the most common queries:

"Should I put sand, geotextile or nothing under the liner?"

 

• AmericanTilapia Recommendation:  

Always use a protective base such as level fine sand or professional geotextile.  

This prevents punctures from stones or roots, extends the life of the liner, and allows better adaptation to the terrain.  

At AmericanTilapia we also offer underlayment compatible with our products.

 

Is it safe to buy a used pond liner?

 

• AmericanTilapia Warning:  

Avoid used or unknown origin liners. Small cracks or hidden folds can ruin your entire project.  

Our liners are new, sealed and verified before shipping. Each piece goes through quality control to guarantee 100% integrity.
