Product Description

Geo

What is Geo UnderGuard?

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 ponds—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.
  • Artificial Turf & Hardscaping – Acts as a durable base layer to prevent sinking and shifting.

This fabric underlayment is a disappointment. It is far too thin to be labeled as 6 ounce. The fabric when unrolled/unfolded and inspected, is thickest at its perimeter. It then immediately thins out to such an extent that I needed to double it over onto itself for it to be of any use. It is so thin, light easily passes through it. It also was fairly easy to pull the fibers apart. For comparison, the Vevor brand I purchased was twice as thick and much higher in quality. I suggest the Vevor, which is a superior geotextile fabric and gives a better estimation of its actual thickness. This Underguard fabric isn't worth the price, in my opinion.

I just laid it down and had much more that I could use. Seems like it will work just fine

Had an issue with a return and they went out of their way to make it right. The product was perfect, it just turned out I didn't need it. Would definitely recommend.

The material in the selling photos make this material appear thick. This stuff is as thin as any other barrier material. At this price and for what they thoat as for using ad an underlayment for a pond is a joke. This won't protect the EPDM liner any more than weed barrier cloth bought at Home Depot

Really hard to use since it came in pieces that we have to arrange now under the liner.

I installed this underlayment beneath the liner on my 10,000 gallon koi pond. It is thick but easy to work with. It seems to be doing a great job, I had a lot of small roots to deal with. I am confident that my liner is well protected. Also, while installing the liner over the underlayment, adjustments to the liner were easy, as the liner moved easily against the underlayment. I did use small biodegradable plastic stakes to hold the underlayment in place while I installed the liner on top of the underlayment. Great product.
