Seal pond liner

[clives]

Greetings,
I have placed a new liner over an old liner.
There are a couple of places where it is not completely sealed.

What is the best material to create a thin seal over the bits that need to be completely sealed??

I have a heat gun if needed.

Thanks
Clive

Ok well what did you use as a liner. What's not completely sealed ?

Hi
I laid a new pvc liner on top of an old liner.
There are a couple of areas where the liner is not sealed.

I want to lay a waterproof tape to ensure a water tight seal. Or is there a better solution??

Thanks
Clive

Pvc has less than a good reputation unfortunately

What would you recommend then??

epdm .45 or hdrpe

Thanks for the advice.

My pond is shaped like a tear, not square.
With the old liner is cemented in

How do I securely glue the overlaps??

Here is a link to @GBBUDD write up on seaming epdm liners. It is very thorough and walks you through the process. https://www.gardenpondforum.com/threads/seaming-epdm-liner.26807/

Whenever I see the title of your thread, I can’t help but think of a pond for seals. That would be cool!
