This pond liner is an excellent basis for building your personal pond system in your garden or anywhere on your property. The pond liner tape is made of premium PVC, highly elastic and tear-resistant, suitable for the design of shallow and deep water zones, and harmless to plants and animals. The pond underlay can easily be cut with scissors. Gluing or welding with PVC (polyvinyl chloride) glue can also be carried out without difficulty. Enjoy creating your little relaxation spot on your ground and floor to distract from stressful everyday life!Important note:1.Before putting the pond lining down, make sure the surface is dry and free from ice, snow, stones and other hard or sharp objects to avoid cuts, bumps and damage.2. You can use the below formula to calculate the size:Pond liner length: finished pond length + twice depth + twice edge overlap*Pond liner width: finished pond width + twice depth + twice edge overlap**minimum recommend overlap 0.10 mIt is recommend to buy some extra metres to compensate for error and to give you enough liner to tuck in around the edges above the maximum water level.3. We recommend the use of a suitable pond fleece under the pond foil. The main function is load distribution and the associated lower mechanical load of the pond foil.
