Underlayment: 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. Nonwoven geotextile 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. Underlayment is EASY to install 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.
