Dustless glass blasting completed on the shell today. Guy said it was one of the hardest shells he has ever worked on. Said normally small pieces of concrete and stone come off with the paint removal on normal shells - not on this one. Doesn't appear to be any major cracks. Some slight surface cracking but nothing that appears to be all the way through the shell. He blasted the top of the shell as well to remove any loose concrete. I will go through and continue with a rock hammer to remove any additional loose pieces. Now for some plumbing work.
JimmytheGreek I have a question that I know you cannot guarantee or give an 100% accurate answer because there are a lot a variables at play. Lets assume that I complete the cleanup and removal of loose concrete perfectly (I am trying my best) and the conditions are optimal and I use the Sika concrete product or a modified cement product similar to that - what do you think the longevity of the repair will be? I don't want to do this again in 5 years. If its a 20 year repair that would make me feel much better about the work I am putting into this. If its 10 years I may consider reshooting the walls on this pool building a rebar cage inside of the existing walls. In 5 years I will be in my 50's and don't know if the body can take this kind of harsh abuse again. 8 hours of swinging a rock hammer hurts pretty bad the next day.I'm guessing that sika stuff is pricey. The concrete you have now is 4000 max. Cheapest easiest way is bonding agent and forms after epoxy pinning rebar or even a small cage if needed. You could do a delivery if there is site access. Otherwise grab pallets and run them back with a skidsteer to a 2 bag mixer. If you add a littlen plasticizer to 5k bagged mix amd use no more than specified water yiu have very strong concrete.......and its cheap
How long do you think the repair could last?Honestly if it were mine I would form it and pour it in one shot with the best mix the plant can send me. I'd look around for a spec mix. My supplier can fortify standard mixes, a 5000psi with some good additives is strong stuff, stronger than what you have there now. I'd spend my time epoxy pinning the heck out of it and making sure it's really nice. Bigger plants have engineering reps that know their concrete amd often have good suggestions and advice, they do it all day long. I dont know how much mud you need but if its alot that sika is pricey. Where are you at with this? Dont swing a rock hammer use an air chisel or a chipping gun.....dont kill yourself over a few bucks
