A Boxwelded liner starts life as a flat sheet. This is then cut to the desired size and then "welded" into place to form a box which will hold liquid. Incorporated into this "box" are what we refer to as "flanges" these are placed under your coping stones to secure the liner in place.
A standard size flange is 6 inches, however, being that every liner is bespoke, a flange of any size can be made (a four inch flange should be the minimum size to ensure minimum fixing requirements).
The more accurate the measurement that you give, the better your liner will fit. For this reason we can quote in the following units;
- Metres
- Feet
- Inches
- Centimetres
- Millimetres
Or any of the above units mixed IE four feet 8 inches etc
So what is EPDM?
- Our products are made from Ethylene Propylene Diene Monomer Rubber (EPDM). EPDM is a synthetic rubber with excellent durability and longevity with high resistance to environmental factors including temperature and many chemicals that would be used by a pond owner.
- EPDM is a synthetic rubber with excellent ozone resistance. This polymer has good heat and cold properties. It also has excellent resistance oxidising acids and other chemicals
- It is a totally man made product so it is friendlier to the enviroment than its Butyl rival.
- It is made in Sweden by Selco (formally Trelleborg), a world leader in its industry and also the home of Butyl. Selco (Trelleborg Elastomer Laminates) is widely accepted as the LEADING EUROPEAN MANUFACTURER OF RUBBER SHEETING.
- Although not recommended it has a stretch of 300% before it will snap.
