My first liner cost just as much as this one and it was half the size. It was to small and it tore easily. My second liner was 75 dollars more then this one and fit perfectly but I was patching it before it even had water. I got fed up and was going to fill it in after sitting for year and a half. I spent so much time and money on pumps filters lights and liners , I had to try one more liner I bought the 20 x 25 and it is great. A sturdier liner that I know my pond will look.great for Christmas. Thank you for selling a product that is described on line. I have never written a review but I'm so happy with your company I had to. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/135379575-underguard-nonwoven-geotextile-underlayment-20-ft-x-40-ft](https://www.desertcart.sg/products/135379575-underguard-nonwoven-geotextile-underlayment-20-ft-x-40-ft) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-20*
