I missed the time when he took the samples :( - I doubt he did a very thorough job, and it did not sound like they intended to repair the side (they are more concerned with repairing other various issues the masonry guys discovered, although it makes no sense to be sticking masonry on a faulty...

Well, the guy said that "for shotcrete, unlike gunite, it is perfectly fine to use wall scrapings on the floor and that shotcrete does not produce rebound"... That is after I sent him the links which he obviously did not look at. Yeah...maybe I look stupid or something. He did take the samples...

Thank you; I requested (nicely) that the company check the areas of the bottom near walls, using the information from the links provided by Chris and JamesW. I will let you know what they will say.

Thank you, this is VERY helpful!!

Well, those are quite some images! I am sure this is not something a pool company will be thrilled to have to do though...

:cry: :cry: :cry: Sorry - I have read this, but when you say "chipping out" I imagined small bits in one spot, but if there are problems over the entire/most of the pool bottom.... :cry: :cry:

Chris - and if there are voids & rebound, what should be done? Scrap the whole thing? Report the company? Is there a way to repair this? I added more pictures - pretty much the entire process. I looks like they shot a layer of concrete on the pool bottom on top of whatever slid down from the...

Well, cracking days after pouring can't be good. And if the bottom is weak, our soil will do a number on it - as the PB knows well, you have to build especially strong concrete structures here.

This is what is looked like when they were building (picture too large to post). The second guy on the right is standing pretty much where the crack is. http://s1061.photobucket.com/albums/t475/a_niceone/

Sorry, double post.

And if they used the rebound and the shell is compromised - the the pool pretty much toast? The will probably want to put some epoxy on it and proceed with everything else...

Yes, that is what it looks like to me, about 1.5-2m, and maybe 2mm wide. I believe the side where the crack is gets a little more sun than the other side, but it really depends on the time of the day. It looks like list of the pool dried evenly, but not perfectly (although water on the bottom of...

I was hoping I was seeing things, but no - there it is, a crack on the bottom to wall transition curve :(.

Re: curing shotcrete - is this a problem? PICTURES ADDED Thanks! I may try the hammer thing (with a little light one!). Construction supervisor came this morning and said to stop watering, it's all good and they will be preparing for the masonry. Today is Wed, and the pouring was last Thur. Is...

Re: curing shotcrete - is this a problem? PICTURES ADDED Thanks guys. I was seriously freaking out. Here is the picture of the entire pool - let me know what you think. It is 40X14, integrated spa, will have automatic cover.

Ykes! All I can say is this sucks! Good Luck!

Re: curing shotcrete - is this a problem? Well, it is not just edges - I am attaching a couple of pictures of spots that remain light when everything is wet.

Re: curing shotcrete - is this a problem? Thank you, this is very helpful. I defintiely plan on taking pictures and getting this on . Also, there is one spot that looks like it is crumbling, but it is not where the color is different, but one of the other edges. I got finally got the...

Re: curing shotcrete - is this a problem? Yeah, I tried that yesterday - it was more of a mess than help, but I can try tinkering with the thing again today. The pool is long and narrow, so ideally there would be 2 sprinklers. Looks like it might rain - that would be helpful... Now, should I...

Re: curing shotcrete - is this a problem? Yes, I think they have used some rebound. It looked like this was a typical practice for this crew. They just told me to water it with the hose twice a day. I am doing more than that today, but I do not see how continuous misting for a week will be...

The pool was poured Thursday. Initially, the plan was that the builders will do the first watering. They finished later then expected, said the concrete was too wet to water, and I should water it Friday. I watered Friday morning and afternoon (it was extremely dry and windy). While watering...

Thanks Matt! I will see the PB today - missed them yesterday because I was at work, but they communicate OK all in all. Crazy, they just started digging this week and now the steel in coming!!!

Wow! I do not know enough to comment on technical details, but it looks great and I am super impressed by how much you saved by DYI!!! Just wow!!

Excavation only took 2 days and it is done. However, PB left some dirt where the ledge and the corner spa will be. I have seen in one of the threads here that all dirt should be removed and steps and spas should be sitting on concrete and metal. Is it true and should I make a stink, or is is...
