What is a pond liner used for?
Pond liners are used in ponds to keep water from seeping into the soil. They work by forming an impermeable layer between the water and the soil which prevents water loss. Pond liners also provide a base for plants to root themselves in and provide a comfortable environment for fish to explore. Inground Pool Liners The reality is that the average inground pool liner will last 5–9 years. I’ve seen many cases where inground pool liners have lasted less than 7 years and other cases where they’ve lasted almost 20 years.The best natural pond liner is bentonite clay due to its durability and permeability.A concrete pond is more permanent than a liner pond. This can be a real advantage if the pond is designed and built properly but a real nightmare if it is not. The inside contour can be built so the pond has smooth flowing walls leading from the top to the bottom drain. This can make the bottom easier to keep clean.If you want a permanent pond, there are really three basic options: 1) excavation into local impermeable soils–with compacting, 2) clay liners or 3) bentonite or chemical additives.Pond liners typically last 20–40 years, depending on the material, installation, and maintenance.
What is the best liner for a pond?
EPDM rubber liners have been the standard liner material for decorative ponds for a number of years. The main advantage of EPDM is that it’s very flexible and malleable. This makes it a good choice for ponds with a lot of bends, shelves, corners and curves that require folding and pleating the liner to get a good fit. Even backyard ponds benefit from a 30 mil or greater liner to prevent rocks and roots from wearing holes in a thinner material. In general, you’ll only find EPDM in 30 mil and thicker sheets. This is because thinner sheets are too fragile and likely to tear on inground debris during installation.Most home and backyard ponds won’t need a specific underlayment, but you may want one even for small ponds if your soil is very rocky or abrasive. Reinforced liners like ours are less likely to rip or tear than non-reinforced materials, but we still recommend underlayment if you’re concerned due to soil conditions.Even backyard ponds benefit from a 30 mil or greater liner to prevent rocks and roots from wearing holes in a thinner material.

What can I use instead of a pond liner?
Fortunately, a liquid pond sealer can be an easy and affordable solution when you are looking for the best pond liner.

A: Pond liner is essential to your pond build, but it will not stop weeds from sprouting on the pond’s bottom like weed control fabric in a garden.Pond Liner Protective Matting Commonly know as underlay for pond liners the protective matting is produced from a strong non woven man made fibre, which is rot resistant and ensures maximum protection for your liner from stones, rocks, root penetration, or sand erosion, beneath the liner.
Is pond liner fully waterproof?
Ponds, also referred to as pond plastic or pond liners, create watertight ponds and fishponds. They can withstand all weather conditions and prevent soil or surface water from entering the pond water by creating a secure seal. Durability and Strength Differences The HDPE pond liners are resistant to UV, oxidation, chemical reactions, tear-resistant, puncture-resistant. The HDPE pond liners are welded by welding machines and not glued, the chances of leakage and seepage are very low. PVC pond liners are flexible but less resistant to UV.
Can I lay a new pond liner over an old one?
It can be very tempting when replacing your pond liner to just lay the new liner directly over the top of the old liner. We don’t recommend this. If the original pond liner has or develops any holes or cuts that are not at the lowest point, these will provide an entry point for water to get between the two layers. The answer is Yes, you can place a new liner over the old one in most cases. Leaving the old liner in place can provide additional cushioning for the new liner. However, it’s recommended to place an underlay between the old and new liner to prevent small stones or pieces of wood from puncturing the new liner.
