About this item
Product details
Anjon Manufacturing's UnderGuard Nonwoven Geotextile Underlayment
adds an extra layer of protection between pond liner and rocky or unstable soils.
It stabilizes soil and prevents air voids from forming between the liner and earth; reduces wear and abrasion from rocks and roots and extends the life of pond liner.
The biggest contributors to Koi pond, water garden, and waterfall failures are poor, unstable soil conditions.
UnderGuard Nonwoven Geotextile Underlayment fabrics are perfect for stabilizing soil, preventing rocks and roots from penetrating pond liner, and for creating 'rock pads' to cushion large rocks and boulders placed in the pond on top of the liner.
UnderGuard Nonwoven Geotextile Underlayment is EASY to install!
UnderGuard Nonwoven Geotextile Underlayment is manufactured in 5', 10' 15' widths and will ship to you in one or more pieces equal to the total square footage of the pond liner in liner/geo combo.
Simply lay the pieces next to each other and install the pond liner. Use any extra underlayment to create pads for large rocks and boulders placed inside your pond.
- 40' x 150' of 6 ounce density geotextile underlayment
- Will come in multiple pieces equivalent to the square footage
- Ideal uses include: pond underlayment, stabilization, weed barrier, landscaping, and construction underlayment
- Manufactured in 5, 10, and 15 foot widths. For installation, overlap geotextile for complete coverage

Underlayment
I think this stuff is mandatory when laying any type liner. It is a strong weave. But I think it needs to be doubled to be truly effective. And the cost for an extra piece is negligible when you consider the cost of replacing a leaking liner. And the price is probably the least of all the costs associated with building a pond. Buy it. Use it. Twice.
