Polyethylene is a good alternative to traditional pond liners. Polyethylene liner can easily retain your garden pond’s water. It can also be easily shaped into whatever form your pond requires. Polyethylene has many advantages over other pond liners.

It’s strong – Polyethylene lasts for up to 20 years. It’s flexible – When building a pond you will need to excavate the area and shape it into whatever form is required.

Excavating clay or concrete means you have to break up the ground which is hard work, but with polyethylene, all you have to do is cut it to the size of your pond and it will mold itself into shape as you fill it.

It’s cheap – Polyethylene ponds are cheaper than clay or concrete ones. This is because the excavation of clay or concrete ponds can be very expensive whereas polyethylene ponds don’t require any major work.

Polyethylene ponds are not without their disadvantages. Facing extreme heat this liner can expand plus release its chemical substance into the water. And the latter one is very harmful to aquatic life in the pond.

It’s easy for plants and algae to grow on them. This means they need to be scrubbed down regularly. And it’s not possible to insulate the pond with rocks or stones. Because it is too thin compared to other liners.

HDPE is a good choice for pond liners. It is very durable and resistant to tears, abrasion, or chemicals. HDPE can be easily shaped around an area where excavation has already taken place. Chemically inert so will not pollute the water.

Being made with polyethylene foam, the pond liner is environmentally friendly and no toxic chemicals are used in manufacturing.

If you have a large pond and need a heavy-duty pond liner, this is the best choice for you. The waterbed liner can handle sharp rocks and sticks without tearing them apart, making it puncture-resistant.

Waterbed pond liner has negative sides too. Waterbed pond liner has very low durability and strength when compared to other pond liner materials.
