I'm certain, as I've said before, that it is NOT the Permadri causing the problem. There has to be some flaw in my construction that is the source of the leak. If it was the Permadri causing the problem, then the whole thing would leak like a sieve. I fully intend to continue to use Permadri products on other projects. This one was a huge learning experience. I think the main possible cause is the construction on the lower right front of the tank where I didn't shim a board that had a void between it and the slab.
What I have proven with this build, is that my construction technique for the tank works and is extremely strong. I experimented with a new coating and found it to be very good. There are very few things i would change, but if I could change one thing it would be going with 1/2" plywood and hardiboard instead of 3/4" plywood to sheath the tank.
The window seal will be easy. After the initial fill to seat the liner and smooth out any bump and lumps, I'm going to install a wood frame around the inside of the window. The frame will be coated with Permadri to seal it. The liner will be sandwiched between the frame and the tank wall. The liner section over the window will be carefully cut out to expose the window.
25' x 30' (24' x 28' is what I need) liner is $315 (cheapest I could find so far), so I'll be saving my pennies. Let me know if you find a better price.

I haven't researched the details yet because Im planning a pond build before next summer, but isn't it possible to custom weld your own liner rather then have it tailor made at significant savings?
I'm not having it tailor made. If you use any of the the online liner size calculators, they tell you the size you need by inputting the length, width, and depth. I'll be using my liner folding technique to fit the liner flush inside the tank.
Neat that is how i bend metal for hvac unit drain pans lol I wish I could get that liner for you

I wasn't implying the permadri was at fault, just it's inability to seal the unknown structural anolmaty on its own. My first guess was always the floor or floor wall seam. Two layers of flooring might indeed be the answer, seams perpindicular to each other. I wonder if a 3/4 inch fiber re-inforced poured concrete onto the floor would have solved the problem.
nc0gnet0, I would definitely go with 1/2" plywood and hardy board (concrete board) over it instead of 3/4" plywood if I could go back and do it again. I've thought about putting hardy board over the existing coating then sealing over that, but that would cost more than the liner. I may do that in the future. The liner is simply a solution I know will work.
id complain to your local permadri product distributor , :grinyes::grinyes::grinyes: oh wait thats you :grinyes::grinyes::grinyes:
lol just joking , i agree with you going for the liner now , its been a long hard struggle with this tank and the sure fire way is to liner it .
how will u seal the window ??? will u pull it and bolt it or use addecive??
