Know the Different Types and Features of Liners for Ponds and Water Gardens

Use Polyex Flexible Pond Liners For Those Tough Lifelong Pond Construction Projects

Polyex pond liner For over 20 years, at Bradshaws we have developed and improved our original pond lining fabric to produce today's top quality pond liner. Polyex liners are flexible, strong and durable with a strength enhancing UV stabilised and rot resistant coating on each side of the liner. The Polyex pond liner is available in black or brown reversible finish and there is a massive range of grades and sizes.

Polyex liners are designed to withstand all natural chemicals and conditions associated with an aquatic environment as well as most preparations sold for pond or garden use. It will withstand whatever type of soil conditions you have.

Talking of soil when you excavate the hole for a liner pond save the soil for use in constructing a waterfall (make sure you know how to select pumps for waterfalls, streams or fountains ... check the links on this site) which you can also make from pond liner materials discussed on this page. With a pond liner it is easy to create planting shelves to suit a variety of pond plants such as bog plants or marginal aquatic plants and even deep water pond plants such as water lilies.

Remove all tree roots, stones, rock and any sharp objects during soil excavation.

For large liner ponds you'll need to bring in construction equipment. You can buy single sheets of liner up to 30 x 20 metres. This will make a large sized pond.

The general equation for calculating the size of pond liner you need is as follows ...

  • Width size of sheet = Pond widest dimension +Depth + Depth again + minimum 1 metre wide to allow for edging overlap on both sides. If you're going to install bog plant planting grooves then allow another 1 metre wide

  • Length size of sheet = Pond longest dimension +Depth + Depth again + minimum 1 metre to allow for edging overlap on both side. If you're going to install bog plant planting grooves then allow another 1 metre wide

  • Example .... if your pond is 2 metres wide and 3 metres long and 1 metre deep you will a liner of the following dimensions (minimum) 2 + 1 +1 + 1 = 5 metres wide and 3 + 1 + 1 + 1 = 5 metres long (remember if you want to create a number of planting shelves then add another 1 metre in both directions.

  • Go to table below at bottom of page and select appropriate available size ...

Standar Underlay Image Standard Underlay (Underlayment to some) protection for all liners

  • Extra thick heavy-duty polythene underlay provides a highly effective barrier for budget ponds.

  • Puncture and tear resistant giving long lasting support for your liner.

  • Flexible, to mould to the contours of your pond.

  • Standard Underlay is sold in sizes which compliment the Polyex Liners. eg if you need a liner 6m x 5m, simply choose the same size for your underlay.

  • All excavations should be lined with river sand before laying the underlay. The sand allows a smooth finish and provides extra protection.

Liner sizes range from 2.5 m x 2.5 m up to 35m x 20 m with many variations in between. Pond construction of virtually any size is thus made possible.

Polyfix Custom Repair Kit for repairing and extending liners

  • Polyfix Tape customises liners to fit oddly shaped ponds, instant for simple repairs, seals holes cut for pipes - no more leaking!

  • The Kit contains two 5m value for money rolls of Butyl and PVC tape.

Upon receipt of your liner, inspect it and store it loosely folded, away from bright sunlight and extreme heat or cold, until ready to use. Our pond liners are guaranteed when underlaid using either Polylay, Polyfibrelay, Standard Underlay or a suitable aquatic brand underlay. Handle the liner carefully when fitting; fold, tuck and smooth into shape before slowly filling with water. Don't allow the weight of the water itself to pull the liner into position. Once installed the liner should not be walked on, stretched or exposed to sharp objects (including animals claws).
