I thought about covering the cracks with West Epoxy System. The large cracks were previously filled with "SikoFlex", a flexible putty substance.

It is downright hilarious doing this kind of research here.
Ask reliable builder, mason or a civil engineer.
Just for example: there is about 100 recipes on the web for a plain "Venison ham roast".
About 85 of those are completely wrong and useless!
I know, I have been hunting whitetail last 40 years.
So good luck!


So why are you such a jack ass?

What are the downsides of using paint, chemical ?
All input is welcome.
Thanks,

If the floor and footer are poured at the same time and the first course of block later, what joins the block wall to the footer? That is, how do you prevent the wall from separating from the floor?

As for pouring a footer , laying the block walls then pouring the floor,, if you're planning on plastering this pool , it wouldn't be the way I would go about it. Footers can settle , then you have a leak around the perimeter of the pool. With the footer dug as you have described , tie all the steel in the floor and pour the footer and floor at one time ,, then lay the block. We pour floors on big commercial pools all the time ,, I'm talking 70' by 150' by 17' deep. and this is how we do it. I have seen pools with the floor poured later and they leak period.

You can drill holes in the footer with a hammer drill and drive rebar down in to the holes. Set the block cavity over the rebar. I have seen most people are putting the rebar in every other cavity. The rebar should extend up past the top layer of block. Once the block are filled, the rebar extending past the top can be bent over and used to tie the deck to the wall. Plus it will provide support to keep your deck from settling.

when the steel is tied for the floor we bend it up against the walls about 2 to 3 foot high so it can later be tied into the wall steel, remember we are shooting the walls so placement is not critical .. If using block for the walls it will take some planning to make sure that the steel comes up in a block cavity or some other approach that the builder seems needed. For example I could see using the block that has half of the webbing cut out length wise, Don't know their proper name but I think they use them for a space to lay conduit or whatever.

Cwalker,
My apologies if this is a dumb question, but what prevents a leak at the wall and footer/floor joint connection when the first course of blocks is installed after the floor/footer has cured?

Is there that much difference between plastering over poured cement and cement cinderblocks? What causes the cracking?

Nota, have you had any problems with the plaster cracking?


The crackinc occirs as a result of shrinkage. You can prevent this by laying the block in mortar and placing a horizontal wire reinforcing in between each course. This is how we bricklayers keep block walls from cracking.
