Atlantic Pond Underlayment - 12' x 25' (PU1225)
Ensure the lifelong integrity of your water feature with Atlantic Pond Underlayment. This professional-grade geotextile fabric acts as a vital protective barrier between your pond liner and the ground. While many beginners attempt to use sand or old carpet, Atlantic’s non-woven polypropylene fabric is specifically engineered to provide a permanent, rot-proof solution that protects against punctures and extends the life of your liner.
Measuring 12' x 25', this underlayment is the perfect size for small to medium-sized garden ponds, waterfalls, and streams.
Key Features & Benefits
-
Puncture & Abrasion Resistance: Protects your EPDM or PVC liner from sharp rocks, jagged roots, and gravel that can shift over time.
-
Non-Woven Geotextile Fabric: Unlike plastic sheets, this needle-punched fabric allows gas to escape and water to drain, preventing the "gas bubbles" that can lift liners.
-
Rot-Proof & Durable: Manufactured from high-quality polypropylene that will not decay or degrade underground, providing decades of protection.
-
Easy Installation: Lightweight and flexible, it easily conforms to the contours of your pond shelf and vertical walls.
-
Stable Foundation: Helps bridge small voids and soft spots in the soil, preventing the liner from stretching or thinning under the weight of the water.

Why You Shouldn't Skip Underlayment
Installing a pond is a labor-intensive process. Skipping underlayment is the #1 cause of preventable leaks. By installing Atlantic Underlayment, you are creating a "cushioned" environment for your liner, allowing it to handle the immense pressure of thousands of gallons of water without stressing against the rough subsoil. It also provides a clean, puncture-free surface for installers to walk on during the liner placement.
