Hello all
Wanted to see if there had been a comparison done on tank liners anywhere on here.I know EPDM has been used but how do alternatives fare up in comparison? taking into account cost and the ability to cope with elevated temperature.

How would LDPE(Low-density polyethylene), RPE (reinforced polyethylene) or any other alternative pond liners perform?
I know it may be a case of get on google and research for myself but i feel a post like this would be of benefit to others too.

Regards Mattie

Not exactly the comparison you were asking for but there are examples of different tanks on the BuildItSolar site.

Matte, in post #24 on the link below is a post concerning my use of liquid rubber. I have had no issues of leaks or any sign of trouble with the use of liquid rubber to date. Would I use it again? Yes.

Thanks Tom.
Thats exactly the type of information that is the most useful,when the install has been done and the design holds up without issue over time.

   I wonder how it would hold up on cinder block tank on a slab, or used in conjunction with the popular cinderblock water sealant drylok
http://www.drylok.com/formulas/latex-base-drylok-masonry-waterproofer/

Has anybody built a cinder block tank right on a basement floor?

Thanks Mattie,
Thoroseal, not sure if it's better than drylock or not but I think I would still put the rubberized coating over it for extra protection. (unless I was just making a hot tub but then I would just find one somebody was getting rid of)

Wait, and old hot tub, that might make a nice tank.......
