10' x 15' 20 mil PVC Pond Liner & Underlayment Combo

Pond Liner is the foundation for any Koi pond, water garden or waterfall. PVC vinyl pond liners are the most cost effective versatile and adaptable liners. They are ideal for ponds of all sizes with steep or gentle sloping sides, tight corners, contours and shelving. PVC liners are completely safe for fish, plants and wildlife. Attaches easily to waterfall boxes, weirs and skimmers. Remains flexible and pliable even in extreme hot or cold temperatures. PVC vinyl liners contain plasticizers which will deteriorate in direct sunlight. For best results use ground cover, rocks or gravel to protect PVC liner from direct UV exposure. 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. The standard warranty is 5 years for defects in materials or workmanship. PVC pond liner is not warranted for UV deterioration.
