PVC Pond liner
These pond liners are available in 0.5mm grade thickness and are suitable for starter ponds up to around 100 square metres (sqm). This type of pond liner is ideal for lower budgets but its lower grade does mean that it has a lower life expectancy, also this pond liner becomes quite brittle as it ages and if you have clay soil can rip when the soil contracts in warm weather.
Firestone Pond Liner
The firestone Geomembrane or Rubber pond liners are a 1mm grade thickness offering high performance, high strength and superb flexibility.
Due to these factors these pond liners are ideal for small garden water-features, ornamental ponds as seen in picture 1 and even larger ponds/lakes and lagoons.
These pond liners are also guaranteed to be compatible and safe for use with aquatic life – certified by toxicity tests performed by the Water Research Centre WRc-NST.
Butyl/Epalyn Pond Liner
The Butyl pond liner has rapidly diminished within the industry over the past few due to rapid increase in the cast of the raw materials.
However Swedish liner manufacturers have started producing a liner called Epalyn which is identical in look to Butyl and exceeds butyl in some areas such as elasticity. Due to Epalyn’s improved elasticity it is an ideal liner for ponds constructed over clay sol as seen in picture 2.
We are happy to try and track down the true butyl liner for you or we can order the new form Epalyn pond liner which will happily do the same job, and comes with the same life time guarantee as the butyl as long as installed in accordance with the manufacturers guidelines.
These pond liners are suitable for medium to large pond and large lakes, reservoirs and lagoons.
The underlay is as important as the pond liner, and the myth of using an old carpet is no longer suitable!
The underlay is a 250 gm heavy-duty geotextile under-cushion and can be seen in picture 3, this pond liner underlay is recommended to protect your liner, working to extend the liners life and to comply with the manufactures installation guidelines.
The underlay we supply is rot-resistant and is designed to protect your pond liner from accidental damage such as root penetration and punctures from stones and other sharp objects.
The underlay can also be used to provide a protective over-cushion on top of the pond liner in a third layer. Over-cushioning will need to be secured in place with soil, clay, or rocks and may be buried into the edge of the pond and back filled with soil using a double anchor trench to prevent a wicking effect.
This is where the under-cushion absorbs the pond water and deposits it around the outside of the pond. This will also provide a natural finish to the installation.
