28 reviews for ThinkMax 15×20 ft Pond Liner 20 Mil Thickness Durable LLDEP Material

  1. Kian simonson

    I bought this liner to put behind my waterfall to stop any leaking. It’s thick and durable, I had no problems with it being too stiff, it was very bendable, it didn’t tear when I placed the rocks on and around it. Very happy with the product and the price!

  2. Jenny

    Used this for a winter skirting because of its durability, thickness and size easy to maneuver where I wanted it. Great value for its size and strength. Will be easy to fold for storage.

  3. Goat mom

    Just as described

  4. Gordon Hughes

    This liner material is very stiff and difficult to work with, seems to be pretty tough though. However it can be cut easily, I dropped my pump and it created a slice in the liner . I think as long as you are careful installing it should last a long time. I had extra so just doubled mine.

  5. miguelson finney

    It’s very thick. I’ve lined the inside with gravel and large stones. I was worried because I have been in and out working on the pump and filter and there’s never been an issue with it leaking. I’m very happy with my purchase!

  6. Daisy

    The packaging was secure and the liner was undamaged. It’s a bit heavy but manageable. Installation was straightforward and it fits perfectly in the space I prepared.

  7. Fiona

    The black color helps prevent algae growth, which is a huge benefit. I didn¡¯t expect such a practical design feature. Really impressed with the overall quality.

  8. Sakib

    This is by far the best liner I have bought yet only thing better would be full on rubber I think. It’s tricky to work with because it’s so thick but ai opened it and left it out in the sun for about an hour while I finished up the hole and then laid it in while it was warm and it went great. I’ve built this pond and river system 3 times prior to this attempt and the liners have always ended up being the problem since they were always to thin and were very easy to damaged. This liner is significantly more damage resistant.

  9. Mason

    The weight might be a bit much for some, but it¡¯s necessary for the thickness and durability. Worth every ounce for the peace of mind it brings to your project.

  10. Isaac

    Easy to work with and sturdy. Handles rocks and boulders without issue. The thickness makes it feel solid underfoot when walking around the pond edges.

  11. Kevin

    Highly recommend for anyone planning a water garden or pond. This liner offers excellent protection against leaks and is built to handle all types of terrain.

  12. Hannah

    Exactly what I needed for my new garden pond. The size is ideal for most home projects. No complaints so far¡ªjust smooth installation and solid performance.

  13. Bella

    Excellent customer service and fast shipping. The liner was rolled tightly but unrolled smoothly. No wrinkles or damage upon arrival. Definitely worth the money.

  14. gi viana

    We used this to line the spillway of our pond renovation. It was easy to lay out, easy to shape, easy to cut. It’s also quite strong – the only thing that poked through was a literal spike from a tree we had cut down. This was cheaper overall than pretty much every option at local stores, and it has held up through heavy rains, storms, and all kinds of critters messing with it. Would buy again if I was doing another water retention project.

  15. Gabriel

    Perfect for a DIY pond build. The instructions were clear and the liner came ready to use. No complicated steps required. Just roll it out and start shaping.

  16. Eric Voeltz

    This is a very thick & durable liner & if you don’t have it in the sun, heated up before you start working with it, you’re gonna hate trying to line your pond with it. But if you do it right & let the sunlight heat it up, it’s easy to lay down. You’re not going to get all the creases out tho. It’s impossible with rubber material this thick. But I wasn’t worried about that, becuz I put boulder sized rocks around my pond to hold it down & it obscures the creases. As for durability…this liner is tough!

  17. Jasmine

    I¡¯ve used other liners before, but this one stands out for its quality and ease of use. The LLDEP material is clearly superior and built to last many years.

  18. Henry

    It took me less than an hour to install this liner. The size is generous and the material is strong yet pliable. Works great for both ponds and decorative water features.

  19. Ethan

    I have a small pond and this liner was more than enough. It¡¯s tough and handles sharp objects well. No issues after several weeks of continuous use.

  20. Felix

    I used this liner for a community garden pond and it held up perfectly. No leaks after weeks of use. Strongly recommend for anyone looking for a reliable pond liner.

  21. Zachary

    Great value for the price! The ThinkMax liner arrived in good condition and covered my entire pond area. Easy to cut and shape as needed. Very satisfied with the purchase.

  22. Caleb

    The black color blends well with natural surroundings, and the UV resistance is a big plus. I’ve had it installed for several months now and no signs of wear or fading.

  23. Alexander

    I love that this liner is safe for aquatic life. My fish seem happy and there are no harmful chemicals involved. Great choice for creating a healthy ecosystem.

  24. Caleb

    The 20 mil thickness provides just the right balance between durability and ease of handling. Not too stiff, not too thin. Perfect for beginners like myself.

  25. Georgia

    Very pleased with how flexible this liner is. It conforms easily to uneven ground. The puncture resistance has been tested by small stones and everything seems fine.

  26. Ivy

    I appreciate the eco-friendly aspect of this product. Safe for fish and plants, which is essential for my koi pond. Also, it looks very natural once installed.

  27. Dakota

    I needed a large liner for my waterfall, and this 15×20 ft size was perfect. It’s thick enough to handle rocks without tearing. Highly recommend for any water feature project.

  28. Elijah

    This pond liner is incredibly durable and easy to install. The 20 mil thickness gives it great strength, and the LLDEP material feels high quality. Perfect for my backyard pond project.
