Pond Liner

Has anyone used this type of woven pond liner?

Thanks @wiseowl . How big is your pond?

 

I am planning a large wildlife pond, approx 7m x 12m. A rubber lining would cost probably over 1000 pounds. I am considering buying one of these type linings. It says they have a 25 year guarantee........whatever that means.

 

I've got butyl and it was built in 1989, still seems ok, but I agree they are expensive if you go big.

In this world you usually, only get what you pay for, is my motto, if it seems cheap, it probably is.

Having said that I'm not answering your question, no I've not tried that type of liner I'm afraid.

Wonder how you go about getting your money back if it fails after 10yrs or possibly less?
The big hassle is replacing it if it is all built in round the edges, if you just use mud and stones not such a problem, perhaps, but still an upheaval you can do without.

 

I have asked Bradshaws to send a sample. One of the things we like about this product is it's light weight. Butyl or rubber is heavy and we have serious concerns about damaging it during the installation process. It will be Mr Redwing and a helper putting it in. We plan to use an underlay as well.

 

You're not by any chance on a clay soil are you @Redwing ? If so would it be worth considering a puddled clay pond? Cheap, eco-friendly and looks like a fun project! how to make a clay pond

Has anyone on here made one? I remember one in the wild bit of my grandmother's garden - the level went up and down quite a lot, depending on the weather, but it looked very natural and I can remember seeing newts in there, so the local wildlife evidently appreciated it.

 

@Clare G we are on clay and tried puddling it but it kept leaking, we suspect because of rabbit tunnels. We did try over a couple of years and have now decided to give into a lined pond. It'll be completely made with wildlife in mind,

 

Had trouble starting my Ferrari this morning bloody foreign motors.

Anyway just thought I'd add, unless a liner gets speared the most likely part to go is the part that is often showing around the top edge, the uv degrades it, so if you keep it covered in earth or rocks right down to below the water line you should avoid that.

 

I've just had to replace a butyl liner after only 20 years, despite it's 50 year guarantee. All because of a bamboo which, although planted quite a way away originally, made a beeline for the pond and pierced 2 thicknesses of underlay and the butyl in 8 places like a knife through butter! Moral: think carefully about which surrounding plants to put in!

 

Thanks for the info @noisette47

I put a barrier in I have bamboo about 3ft away from the pond blue arrow, I put paving slabs vertical red arrow, the bamboo is raised in planters with no bottom in, hopefully ill have no problems I might cheese wire the bottom of the planter every few years as a precaution.
