OK thank you so much for all of your time on this- it really helps to have someone knowledgeable to ask all these questions and get some ideas before going back to the PB. I will indeed see how the PB responds to wanting the full depth expansion joint.

Correct- they did NOT make any plans to show me- but I do remember the general guy warning me before they started that the new stairs would have a line through them for a movement joint. I did not know much at the time and forgot about that until it was finished and I saw cracks in the coping...

OK. The stairs on one side of the spa are about 6.5 feet and almost 8 feet on the other side- so a bit more surface then three feet. But I get what you are saying. And we do have very clay soil which definitely expands/contracts a lot with the seasons. For this situation, though, I'm not only...

Unfortunately we weren't here when original pool was put in.. and I can't find a better pic of the demo state.. but - that last pic I sent- if you look at the lower left side- it looks to me like just concrete under the rubble. And if you look at the right side it seems there's a cracked line...

This was just a remodel- so they had demo-d the stairs down to rubble and poured concrete over that rubble and actually lengthened the tread from 9" to 12". Here is a pic of after demo and before they added concrete- and to my eye it looks like concrete- not shotcrete- but can you please tell me...

(I think I just lost my latest reply- so my apologies if I did not and they both come thru) I was thinking the same- that caulk is not a good solution- otherwise why not just always caulk instead of grout? The temp was mid 90's when they installed.. but they tell me now that if they regrout -...

Yeah- I thought caulk was NOT a good solution... but the mason said if they redo grout it will just crack again- which makes me think they think it was NOT too hot a day when they installed it? (it was 90's- so it was hot- but if they think installing it now on a 70-80 day will crack again- then...

I did speak with the PB and they sent a mason out who wanted to caulk (siliconized acrylic caulk) to fix them all- but he had the wrong blue color and I wanted to do more research before letting him do that- so I only let him do it to the brown mortar above the sheer decent- not to any of the...

Also- how can you tell visually the difference between shrinkage and movement cracks? TIA.

Thanks for looking.. so this is brand new grout- is this to be expected within a few weeks always of new grout? Then I'd have to do new grout many times per year to keep it nice? Or do you think one new layer at this point could keep it nice for a longer time?

Hi ajw22, I had posted some pics that day- but realized now that I didn't put that as an answer to your response-(see below in main thread) so maybe it did not let you know. Any thoughts you may have further on this would be appreciated. Thanks!

OK here are some pictures: 2 pics of sample cracks. It is in many places in the side walls that have the stairs- so I can't show it all. 1 pic that shows a crack in the coping mortar connecting to tile grout cracks: I did have the mason guy fix that brown mortar with caulk (after this picture...

I will get some pics loaded up here soon.. we have not had any earthquakes lately.. and I'm not seeing these cracks in other areas of the pool. The only thing I would think would have moved would be the clay soil under the concrete decking contracting due to these last months in summer heat. And...

Hey Texas Splash- thank you!

Thank you, mknauss! I believe I had read through the basics here many months ago as a "lurker"- but I should check it out again!

Hi there. I'm new to the site due to an issue coming up with our completed renovation that I can't figure out. Any help would be much appreciated! Just a few weeks after tile and grout were put in we found some cracks in the two side stair areas of the spa wall. This was after having realized...

We bought the house in 2018, and have slowly been figuring out things about the pool (built late 90's). It's the first in ground we've had, and didn't know much about the above ground from a previous home. This year we finally had to get new surfacing and a new skimmer and decided to also update...
