Pond Liners

We offer a quality underlay and a comprehensive range of pond liner materials to suit most pockets. At our works in chesterfield, Derbyshire we seam weld stock rolls to fabricate any liner up to reservoir size! Our motto at county is "when it's up to quality, not down to price" because we only use high grade selected materials. We sell direct to the public so you get excellent value for money bespoke liners.

To help you choose:

Butyl Rubber:

Top of the price range is butyl rubber which is the name given to the class of synthetic rubbers made primarily from butyl-polymer. Although there are hundreds of ways to formulate butyl rubber from butyl-polymer, all share a chemical structure that gives them extra-ordinary resistance to moisture transmission and biological decay, as well as exceptional elasticity. Butyl has been primarily used for waterproofing in protected environments under earth or water where long term durability is essential, such as for lining ponds, lakes, canals, reservoirs and landfills. Butyl, being non-toxic, is harmless to fish, pond life and plants. Available in 0.75mm or 1.0mm thick, butyl rubber withstands arctic cold to desert heat. Guaranteed period is 35 years but tests show you can expect a minimum of 40 years in harsh above ground environments and better for underground/underwater. Whether you're lining 25 or 4,000,000 square feet, butyl offers a better natural drape with increased flexibility and decreased tearing, so obviously it is the most expensive option

EPDM rubber:

This synthetic rubber is relatively inexpensive to produce and it carries a 20 year guarantee. During the manufacturing process, the long rubber molecules join together by chemical crosslinking to give an elastic, flexible membrane. it is stable to temperature changes, chemically resistant and returns to its original shape following stretching. The crosslinking gives EPDM negligible aging over long periods of time despite exposure to sunlight, atmosphere, UV-radiation, chemicals, water, temperature fluctuations and extremes. It contains no plasticizers or additives which can evaporate or leech out over the years. the strength and elasticity remain virtually unchanged over decades without shrinkage, melting, hardening or cracking and it remains flexible within the temperature range of -30°C to +120°C. our standard grade is 0.75mm thick and is suitable for all types and sizes of pond.

Heavy duty PVC:

This economy material is 0.5mm thick but is only suitable for small to medium ornamental and wildlife ponds. not suitable for fish breeding. it carries a 15 year guarantee but its quite an unforgiving substrate which is susceptible to mechanical damage and dislikes disturbance. However, it can be repaired in situ relatively easily. Sheet sizes climb in increments upto 10m x 25m

Geotextile underlay protection:

Geotextile liner protection fabric is a tough synthetic fabric typically used below garden pond liners to help protect the rubber from puncture from rocks, roots and other soil debris. Unlike sand bedding, carpet padding (never use old carpet!), and old newspapers commonly used for this purpose. Geotextile protection fabric also protects against puncture from objects above the liner by limiting how much the liner can stretch under pressure. When garden pond liners are covered with soil, gravel, rocks or concrete, fabric should be used both above and below the liner.

Geotextile liner protection fabric is a non-woven polyester fabric with optimal characteristics for pond construction. Geotextile 300gram M2 is substantially thicker than fabrics commonly used for landscaping and soil filtration, being ideal for difficult terrain. It is extremely flexible and conformable. Since it does not deteriorate under a wide range of soil pH and is essentially non biodegradable, it will last as long as your butyl pond liner. Its heat and sunlight ability makes it suitable for use under reservoir liners and flood barriers where levels fluctuate.

Repairs and Seams:

Should you inadvertently damage your liner, it can be permanently repaired with our self-adhesive tapes.PVC repairs are easily done, but have a limited lifespan. Stream and waterfall liners can be easily attached to pond liners.

Sizing notes:

1. To find the size of the liner that you require, you will need length (L), width (W), TWICE the depth(D2) and TWICE the amount of overlap (O2) you require round the edge of the pond.
2. calculation: (L+D2+O2) x (W+D2+O2)
3. example:

L = 10ft
W= 7ft
D=1ft 6ins (so D2 = 3ft)
O= 6ins (so O2 = 1ft)

10+3+1 = 14ft
7+3+1 = 11ft
14 x 11= 154 sq ft

If you are unsure of the liner size you require please contact us with the length, width, depth and required overlap and we will calculate the size for you
