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.

I thought I’d need more but one piece was perfect. It’s very strong and yet folds easily to fit the deeper dips.

I just installed this liner, seems durable, which makes things a little challenging to maneuver at times... time will tell.
