PIK Koi Pond Liner - 60 Mil Ultra

The most versatile liner on the market being fish & plant safe, with high puncture resistance, AquaArmor is the strongest, most UV-resistant pond liner in the industry! This 60 mil is our strongest Pond liner available and sports a whopping bursting strength of over 880 PSI!

While this liner is incredibly strong, the tradeoff is that it is stiffer and less malleable than the thinner RPE liners. The 40 Mil Ultra and 60 Mil Ultra are only recommended for larger installations where the additional strength is necessary, and it does not need to follow tight curves. For most pond installations, the 30 Mil Ultra is the best balance of strength and malleability.

IMPORTANT: Liner does not qualify for free shipping. Additionally, these liner orders are not eligible for return as they are all custom cut to your specs. For this reason, we'd recommend digging your pond first and then measuring it out and ordering your liner so you know exactly the dimensions and don't end up being short.
