Pond liners are undoubtedly the most cost effective way to line a fish pond or water feature. Although most modern pond liners now come with a lifetime guarantee it usually only covers the liner for UV damage or failure in the factory sealed seaming process. Fish pond liners are manufactured with a width of about 2m. The two meter lengths are then seemed together at the factory to produce the various sizes we all buy in liner packs or off the liner roll stand.

An occasional problem for pond liners that is not covered under the guarantee is that it is possible to pierce or puncture them. This could be accidental or caused by the dreaded heron, and on occasion pierced by a root. I personally have only ever seen bamboo roots pierce a decent liner so beware. A plant or tree root can grow though a liner but in my experience there has to be a hole in the liner first.

If you think the heron has caused a hole there is a simple way to know. When you find the hole check to see if it is an upside down v shape. Herons beaks are v shaped at the end and when they attack your fish they often leave you with a leaky pond, so if you do find this to be the case you may need to think about protecting your pond.

Liner Repair Techniques.

Splice adhesive, liner tape and liner off cut. Score 5 out of 6
This is by far the most effective way. Once you find the hole clean the area around the hole, coat the affected area with a small amount off slice adhesive and leave to go tacky. Cut your tape to adequately cover the hole and lay on the tacky adhesive. Then add more adhesive to the top of the tape, leave to go tacky. Cut your liner to size and lay over the repair. This strengthens the repair and protects it.

Mastic tape. Score 2 out of 6
This is sold by most shops. It is a black sticky tape and has been used to repair liners for years. To work the affected area must be clean and bone dry before attaching the tape. In my experience this is not a full proof method. It may work to start but can come away in the long term.

Silicone like products. Score 4 out of 6
There are a lot of different types off this product. Always make sure what ever you are using is fish safe. Failure to do this could cause fish loss. Some of these products claim to work underwater but I would not recommend you do this. Add your sealant to the liner surface once you have cleaned and made it bone dry. Cut your liner to shape and then roll it over the surface and leave to dry in the air for 12 to 24 hours for maximum effect.
