6oz Nonwoven Geotextile Underlayment

Koi Pond, Water Garden & Waterfall




6oz Geotextile Koi Pond, Water Garden & Waterfall Underlayment

The biggest contributors to Koi pond, water garden & waterfall liner failures are poor, unstable soil conditions

Nonwoven geotextile fabrics are probably the most commonly known geotextiles. Nonwoven polypropylene fabric, which has a felt-like consistency, combines strength and flow ability. The fabrics are strong but permeable, allowing for varied uses. Nonwoven fabrics commonly are used as to stabilize unstable soil, prevent rocks and roots from penetrating pond liner from below, and is often used by landscapers to create “rock pads” to cushion large rocks and boulders placed on top of pond liner. Nonwoven Geotextile Fabrics have a random, three dimensional pore structure and are highly water permeable, as is necessary in many geotextile end uses.


·         High tensile strength pond liner underlayment is easy to use

·         Provides a stable and lasting foundation for Koi ponds, water gardens and waterfalls

·         Is used by landscape contractors to create rock pads

·         Virtually indestructible; unaffected by hydrocarbons, mildew, rot & freeze-thaw cycles

·         Enhances soil stability and controls erosion

·         Diffuses gas and fluid build up   



Don’t Settle For Less!

Many home stores, garden centers and online resellers offer lighter weight pond liner underlayment, often as lightweight as 2.8 oz. Given the total investment you are making in your project, the additional cost of a higher grade underlayment like our 6 oz product is worth it to stabilize poor, unstable soil conditions.  .
