    How do I fix this crack

    Pool cracked in the corner and I chiseled it out to let the water drain. Pool builder is not an option. I want to seal this crack, if possible, with hydraulic mortar mix, I then want to fill that corner with concrete, and build out and extend the stone down from the water fall to the bottom of the pool. What type mortar and concrete should I use for this? Also, is necessary to tie the new concrete into the existing pool wall with rebar? I can do this. I just need to know if I am on the right track.

    Thanks

    Yikes! I see in your other posts that your pool is ~4 years old, right? I know you said pool builder is not an option; I'm guessing that means they're out of business? Otherwise this is their problem to fix. Sorry I can't be more help, but others should be around soon.

    Hydraulic cement should work and if I didn't do anything else, I'd chisel a few holes in the existing shell and anchor a few pieces of rebar in it. It'd be good to have them span the crack but that may not be possible in every place.

    bore or chisel a hole on both sides of the crack and span it with a piece of rebar so it's anchored on both sides into the concrete.

    Great photo. What about an epoxy to go into the holes to bind the rebar?

    Definitely use epoxy and a waterproofing additive and don't forget to blow out the drill holes with a compressor. I'd also consider adding short glass fibres to the mortar mix too. Great photos.

    Hello, My name is John Kells with http://WWW.ADVANCEDART101.COM and I think that you have more problems then what meet the eye in your pictures. Please take a moment and research deep before going down this repair road.
    I have 30 years of experience doing such repairs that other people built, and believe what you want, but, this is very serious if not done right. I will step by step what I see to be your cure if you want to go it alone.
    #1 Chip out all concrete until it is clean and free of lose pieces. #2 Clean rust off of rebar #3 Drill 1/2" holes in the middle of the wall every 6" to epoxy in 3/8" rebar that will be 6" deep on each side #4 wash out holes
    and concrete, allow to dry fully #5 fill 2/3 with epoxy in the drilled hole one level at a time, add steel with the extra length to allow for your crack span #6 Put a form on wall to allow for pouring your repair material
    #7 Before it is dry, remove form to rough up the wall with a stiff brush so that the plaster sticks better ( wet down the old cement before adding new material to assure a good bond, and rub it in with your hand at the point
    of bond to help even more ) I hope this is good enough of an explanation for you, good luck!

    As am I. Not sure you would be able to get that kind of advice anywhere else, even for a fee.

    Super advice! Thanks. What size rebar? this site is worth way more than $30.00.
