Hello: I am new here but this forum is great! Thanks all! I have a existing gunite in-ground pool at our home and I am remodeling and upgrading it to add a baja shelf of 7' X 15' in the shallow end. I am a general contractor but have no experience with pools so I am learning. We have chipped the plaster off down to the gunite and tied steel to form the baja shelf and new steps which will be shotcreted in. My wife wants an umbrella sleeve in the center of this new baja shelf. I purchased a 7" long plastic sleeve w/ cover which is Aqua Star US101 (or US00-08 on body) but NO instructions or diagrams. I would like to know if this sleeve should be tied into the steel and shotcreted into place or if I should have them leave a pocket in the shotcrete and install this new sleeve with just the plaster holding it into that pocket.?? I did call Aqua Star and the tech was very nice but only said it could be done either way, whatever I want to do. I have no idea what is correct and the best proper way to do this. At what height is the sleeve itself set at? Does the main body of the sleeves top set flush with the shotcrete and the slide-in top portion install after plaster or what? Any help or drawings here would be much appreciated. Lance P.S. I tried to post a picture but it says file is too big & I don't know how to reduce it. It is 1.7MB ??
