Water Bar in floor joints 1

[aoifeeng]

I need help in designing the most practical and latest method of inserting a water bar in an induced joint in the floor of a reinforced concrete effluent holding tank.Also has anyone experienced serious attack on the concrete in covered effluent balance tanks and what might cause this.
Any help would be welcome.

I do a lot of concrete tank design. But almost all your terminology has me baffled.
Is water bar the same as waterstop?
What's an induced joint?
What do you mean by serious attack on concrete? Is it chemical attack? Is the reinfocing exposed, aggregate, etc?

Thanks for the responce Jed.Water Bar is Waterstop.An induced joint is formed by placing a crack inducer in the bottom of the slab and making a saw cut along the line of the crack inducer on the surface of the slab. The attack on the concrete is chemisal and while no re-bar is at present exposed it will eventually be so if the attack continues.

Now I understand:
To replace the waterstop, use Sikadur Combiflex. See: (

It's a surface applied, bandage looking, strip of hypalon adhered with epoxy.
As far as the chemical attack, it all depends on the chemical doing the attacking. But most repairs involve building up the deteriorated area with a chemical resistant grout and applying a coating over that. Check Sauereisen for different systems,
