When constructing a pond, water feature, or any containment system, the foundation beneath your liner is just as important as the liner itself. UnderGuard Underlayment by Anjon is a premium-grade geotextile fabric engineered to enhance liner durability, prevent damage, and extend the lifespan of your water feature. Unlike traditional materials like sand or carpet padding, UnderGuard provides superior protection against punctures, shifting ground, and environmental wear. Why does UnderGaurd stand out? Superior Puncture & Tear Resistance – Made from high-strength, non-woven geotextile fabric, UnderGuard acts as a protective barrier, preventing rocks, roots, and debris from damaging your liner. Enhances Drainage & Stability – Unlike plastic sheeting or inferior materials, UnderGuard allows for proper water drainage, reducing hydrostatic pressure and preventing water from becoming trapped underneath the liner. Safe for Fish, Plants & Wildlife – Made from non-toxic, Wildlife safe materials, UnderGuard is completely fish- and plant-safe, making it ideal for koi ponds, water gardens, and natural habitats. UnderGuard Underlayment is designed for more than just pondsβ€”it’s a multi-purpose solution for various outdoor and containment projects Ponds & Water Gardens – Provides a protective base for EPDM, PVC, and RPE pond liners. Retention & Drainage Basins – Improves water flow while stabilizing the ground. Foundation & Erosion Control – Reinforces ground stability in landscaping applications.

Liner and Geo Combos 45 Mil & Underlayment 60 Mil & Underlayment Review: Finally a great liner from a great company!!! - I started my pond at the end of 2019. 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.
