Concrete Ad Mix Kalmatron KFA 1

[Ogrork1]

Has anyone used Kalmatron KFA as an admixture in structural concrete? They say that it alone has been used to make water proof swimming pools.

I'll bet they do.
Making waterproof concrete is a function of skilled installers, good details and a low water to cement ratio. There's no magic dust you can add to the concrete that has any more than a small effect. And I'd be very suspicious of anyone who over promises the results of any admixture.

Ogrork1,

Did you find out any more information on the use of KFA? Does the product perform as Kalmatron claims?
