 About Pond-Grade 'BUTYLITE' Rubber
BUTYLITE is a premium, synthetic rubber pond liner recommended by leading European water gardening experts. It has been field tested for more than forty years in hundreds of thousands of installations throughout the world, varying in size from 25sq. ft garden ponds to 4,000,000sq. ft water storage reservoirs. It is remarkably flexible and comfortable, it is safe for all aquatic life, it withstands exposure to artic cold and desert heat, and it will last longer than any other flexible liner underwater and underground. Although BUTYLITE costs more than other synthetic rubbers, it has superior performance combined with an unlimited range of sizes and shapes which easily makes it the liner of choice for projects of any size that demand the very best liner available.
Formulation
BUTYLITE is fabricated from a unique BUTYLITE rubber formulation optimised for pond liner use. It differs from other Butyl rubbers commonly used for commercial waterproofing in four important ways. It is completely safe for fish, plants and plant life, it contains some traces of polymer for superior durability in exposed applications, it has a talc free surface for easy handling and attractive appearance, and can be factory seamed with a high strength hot bonding process.
Lifetime
We guarantee our rubber BUTYLIFE liners for 35 years. Extensive field experience suggests that they will last longer than forty years in severe above ground environments, with even more life expectancy in protected underwater and underground environments. Other manufacturers may claim their liners can last as long as BUTYLITE but none have the track record to prove their claims.
Thickness
BUTYLITE liners are available in .75mm and 1mm thicknesses. Irregular free form garden ponds, particularly those smaller than 1,500 sq. ft, should be lined with .75nn BUTYLITE: no other pond liner is more subtle or elastic and none can be installed with so few folds. Larger projects should be lined with 1mm BUTYLITE for enhanced resistance to abuse since the thicker sheet offers significantly greater strength with only a little loss of flexibility.
Appearance
The talc free process used to manufacture BUTYLITE gives a slightly textured surface with a flat black colour.
Repairs & Seams
Should you inadvertently damage your liner, it can be permanently repaired with our self adhesive tapes; stream and waterfall liners can be easily joined to pond liners with our self adhesive seam tapes. Although we advise against ‘field seaming’ pond liners, unless the project is too large to be lined with a single sheet of rubber, durable seams can be made by using a combination of seam tape and repair tape. |
