Cold Joint Seal
Cold Joint Seal
(OP)
I'm designing a 6 inch thick 6'x4'x7'deep concrete structure to hold water. The structure will be burried into the ground with only 6 inches sticking out of the ground. Construction will be pouring the slab first, then pouring the walls, creating a cold joint. Will this cold joint leak a lot of water if any at all? and if so, how do i seal this cold joint?

For a larger box, with higher water level, you might have more of a leaking problem.
Don't use hydrophilic waterstops on narrow walls as the expansion of the waterstop might blow off the concrete along the edge.

Also, were major concrete dams like the hoover dam constructed using water stops at construction joints? It doesnt seem to leak much if any at all from what I recall.

all dams leak, seepage through dams is a major issue, Hoover Dam included. First major use of rubber waterstops was on Hoover Dam.

They build dams out of dirt and rock, but you wouldn't build a swimming pool out of that.

And thanks cvg for that link. It was really helpful. I think I'll be using the rubber waterstop on the water side of the rebar to protect both from leakage and the rebar from rust. I do have a question on the hydrophilic waterstop though. If I made a 10 inch thick wall with double curtain, and placed the hydrophilic waterstop in between the rebars as the pictures in that power point imply, wouldnt that push the gap to become even larger and cause the rebar to rust?
