Geotextile Underlayment

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.
