Which Liner and Underlay should you choose.? Whether your pond is a natural pond, home to a few Goldfish or has giant Koi it has to hold water, and in most ponds the water is kept in with a liner. The process of building a pond is not something too many people would cherish having to do twice. It is therefore important that the correct liner and underlay (if needed) are chosen. If not then the pond will not be water tight and the whole project may need re-doing. You cannot predict every eventuality but spending some time working out the risk and threats can save time and money later. The risks to liners come from above and below. From above they are predominantly from claws and accidents. The claws could be dogs, cats, ducks and herons. From below the risks are from stones, flint, rubble, underground pipe work and roots (existing and new systems). This is not a full list, but some of the most common problems we have come across. If you believe any of these maybe a problem then we would recommend using the stronger liners and underlay i.e. Greenseal, Firestone or Butyl liners each with 250g underlay. However, if you do not believe the liner is under any threat then a budget option may be a 0.5mm PVC liner.

- Greenseal EDPM Pond Liner
Greenseal EPDM pond liners are the modern alternative to Butyl ponds liners. These 0.75mm EPDM pond liners come with a Lifetime Guarantee. Greenseal EPDM pond liners have the same if not better UV stability, weather tolerance and strength properties than Butyl, but at a much lower price.
- Firestone EDPM Pond Liner
Firestone EDPM is a 1mm thick rubber pond liner. Firestone EPDM rubber pond liners have almost exactly the same properties as 0.75mm Butyl pond liners, but have even better weathering capabilities and because this is 0.25mm thicker than the Butyl pond liner you will end up with a stronger product for less. Supplied with a Lifetime Guarantee.
- Butyl Rubber Pond Liner
Butyl pond liners are made from 0.75mm rubber. Butyl is very flexible which is why it was the favoured material when lining ponds where a lot of folds are expected. Unfortunately repeated price rises have made Butyl a more expensive option. Whilst it is not guaranteed against puncture, the flexibility of a Butyl liner helps to guard against puncture. It is offered with a Lifetime Guarantee.
