## Description

Outdoor and Garden Bestsellers

Review: Exactly what I needed - I’ve only had it for a couple of months, but I have every confidence that it’ll last forever. Very thick and sturdy, yet easy to manage and cut to size. I’m happy to have found it and I feel that it is worth every penny. Thank you (from me and my fish).
Review: Reliable material - Very minimal thickness . This should not be an issue if you have a previous molded liner or SMOOTH excavated EARTH depression. I DOUBLED mine over because of MORE THAN enough material for a 7 x 4 x 2 ft. DEEP pond. Easy too, as felt like, NON-Woven underlayment material molds itself to surrounding pond depression with some effort.

## Features

- Enhances Stability and Integrity: Prevents liner sagging and shifting, helps control soil erosion, drainage and maintains structural integrity of the pond ensuring even water distribution.
- Longevity and Ease of Maintenance: Reduces the risk of premature wear and tear, minimizing the need for frequent liner adjustments and upkeep for outdoor ponds.
- Heavy Duty and Versatile Use: Made with commercial grade non-woven geotextile, suitable for large, medium or small fish and Koi ponds, landscaping, weed barrier and construction projects.
- Measures 10 feet wide by 15 feet long. Includes 15 garden staple U-pins to stake down the non woven fabric for easy installation and hassle-free pond underlayment setup.

## Questions & Answers

**Q: What is the size of the REKVEN underlay, is one enough, and how long does it last?**
A: It is 10 x 15 feet, perfect for most small to medium ponds, but always check your liner size. For larger ponds, you can overlap multiple pieces or fold/double the underlay for extra thickness. When installed correctly, it can last 20 to 30 years.

**Q: Is it suitable for waterfalls, fountains, streams, bubbling rocks, salt and fresh water ponds, and other waterscapes?**
A: Yes, the underlay is ideal for waterfalls and other waterscapes like fountains, streams, and bubbling rocks. It offers strong support and protection beneath liners to help prevent punctures. It’s suitable for both freshwater and saltwater ponds.

**Q: Is a pond liner underlay really necessary, and do I need to do anything before laying the fabric?**
A: Without an underlay, your liner can be easily punctured. Before laying the fabric, it is important to clear the pond area of rocks, sharp debris, and roots. A debris-free, clean, level surface will maximize performance and the fabric’s lifespan.

**Q: Is it thick/durable and permeable, and UV resistant?**
A: The fabric is thick and durable with a high-density 4.5 oz/yd² weight. It is permeable by design to allow for drainage. While strong, long-term exposure to direct sunlight is not recommended as it may cause degradation.

**Q: What is the recommended overlap for multiple underlays, and will the underlay work with different liners?**
A: We recommend overlapping each underlay section by 4 to 6 inches to prevent gaps and create a smooth base, securing overlaps with the included U-pins. The underlay will work with all major liners like EPDM, PVC, HDPE, LLDPE, and RPE.
