We recently dug a good sized pond, and Mr Jacnal being so impatient has gone and used a clear plastic sheet which is fairly old, and filled the pond. It must have holes in it, because the water disappeared days later and only left a muddy puddle. Oh, he's convinced the mud is good for the pond, but I disagree. Anyway, my question is, what lining is best for a pond? Something hardwearing and durable, but what is it called and where can I buy one?

its called butyl liner for ponds  . if the pond is 4ft square and 2 feet deep with square sides  you need 10ft by 10 ft to allow for the drop and the edging

Thanks Munty. I'll google for suppliers.

It's only a small pond, and round-ish. Will measure approximate size, but I'm sure it's diameter is less than 1 foot.

I'm sure it's diameter is less than 1 foot.

 :shock:  :shock: that's a puddle not a pond

It's a pond! A amall one WG, but will soon be functional - wait and see! (prays to God the frogs come and set home in pond).

not in that amount of water ............. its a foot diameter thats a dinner plate isnt it? it need to be at least 3 ft across all sides and at least 3 ft deep or it wil freeze over hard and kill everything in it .it needs to be sheltered from northerly freezing winds by some sort of screen be it bushes or pallets  also sheltered from the direct sun or it will dry out

Ooops, I meant 1 metre. Feet and inches confuse me. I do well with centimetres and metres  :oops:  :oops:   !

It's deffo bigger than a dinner plate  :roll:

It's sheltered by fruit bushes and 2 plum trees. I'll be covering the top with wood, and thinking of planting the green manure type grasses around it. I'll post a picture once it's decent looking. Too rough at the moment  :oops:

A butyl liner should be laid on top of sand to prevent damage so you will need a lot.  You can use the remainder to grow carrots.

Chat up your fellow allotmenteers to see if anyone wants to share a tonne bag with you.  If you are in luck, one of them might be/know a builder.   Or get a quote from a builder's merchant.

its a good idea aswell has using sand under the liner to use another liner ontop of the sand,like a carpet or a proper pre-liner.especialy if you have trees near the pond as the roots can burst through over time.and another thing to think about is the plants that you put in the pond.some rushes have very strong root systems and these can rip through the liner so if you plant these put them in tubs/pots and keep your eye on them.

Also you might need to get in the pond at one time or another.  Easy to damage liner against even a small sharp stone

So much to consider that we obviously didn't. This will sound silly, and we were  :oops:  :oops:  :oops: ......

The pond was dug in the place where a black currant bush was. The root went in too deep and although we got a big chunk of it out, we didn't get all of it. Didn't use anything else to kill it. Is it possible it might come up again, or would the pond stop it and kill it off?

This is all Mr Jacnal's fault too    he was in such a hurry to put a pond in, obviously not thinking of what might be involved, the silly man. Does this possibly mean undoing all the work I've done around the pond? I'll get him to do it all, and be bossy whilst I supervise, lol!
