Water Storage Tank Liners
Water Storage Tank Liners
(OP)
I have a project that would require lining a water storage tank (for potable water). The water storage tank is steel, bolted, and epoxy lined. The tank leaks at the gasket, between the bolts. I was wondering if anyone has any experience with "spray-on" tank lining epoxy, if so, what are the advantage and disadvantages? A couple of companies I was looking at are at the following links:

The rubber gasket between the plates will flex due to changes in water depth and ambient temperature. Epoxy linings tend to be very hard and would crack in this application.
Is the bolted tank manufacturer not standing up to his warranty? If you want to fix your leaking tank have you considered using RTV silicon to caulk the gaskets to the tank walls?
Epoxy linings in welded steel tanks are a good alternative.

Rubber was banned as a material in
potable water systems many year ago,
because it supports Legionella
proliferation. If those gaskets are
indeed rubber they need changing.

The only solution is to remake the joints.

Do you or your company have any
data for the relative Legionella
growth/proliferation on that
polyurea material?

Most spray applied products depend on surface preparation for success.
Whatever the case may be you should speak to someone who specializes in coating the type of tank you have and has seen the application years later to determine strength and durability of the product.
