HDPE welding.

[Big woody]

Hi, I am building my own pond and have acquired a roll of HDPE 1.5 mm liner but need it fusion welded. Is there any companies that would do this sort of thing I am in the south Gloucestershire area. Thanks.

Welcome!

Here is a good step by step on how to seam liner if you want to try it yourself.

Seaming EPDM liner

Seaming is not difficult but it does require some foresight and thought. Hopefully this list will help you to create a seam that will last for many, many years, issue free. If you can seam your liners in a driveway or somewhere flat that is by far your best option. The method below is how I...

I believe HDPE can't be seamed like EPDM. I'm pretty sure it has to be "welded" together, as the OP stated. I wouldn't try using EPDM seaming techniques on HDPE. The materials are totally different.

I hope you find someone that can do that for you.
My fear is if you can even find someone it might be cost prohibitive. It might just pay to get a new liner and use the one you have for something smaller. Maybe make a stream that flows into a pond.
For my recent bog build I used HDRPE which is similar to your HDPE, but is reinforced. I bought mine online from American Talapia. A 12 ft. X 20 ft. piece with free shipping was under $150 (U.S.). I believe you are not in the U.S., so I don't know if the shipping would still be free.

Yeah, I figured you just overlooked the type of material. Probably just meaning to add a quick helpful response.
I just wanted to make sure that the wrong seaming kit wasn't used.
Years ago, my novice self seemed two PVC liners. Not knowing that I used a seam kit for EPDM, a failure was eminent. It was disastrous of course. Then later I also discovered how terrible PVC liners were in general. They get brittle in a matter of months and puncture very easily.
Live and learn... That's why I like to share my experiences with new ponders. Trying to prevent heartache and wasted money.
