So i've read several threads where folks use some PVC fitting to create an Umbrella hole in their pool decking. On tread talked about how they worked with the concrete guys to incorporate them in the pour.
My concern with this is placement. Seems to me that I won't know where i really would want an umbrella until several weeks into the summer. I won't know where i end up sitting, where i ended up laying, where the wife likes to sit, kids etc.
Does anyone have any experience with doing a core drill on pool decking concrete after it's cured some to make umbrella holes? My deck (patio too) will be poured out of some "special pool mix 4000 psi" that i understand will not have much (any) aggregate in it. If that makes any difference on the ease of drilling.
My concerns are getting a drill bit to start a hole without jumping around, and with the PVC holders they extend a little bit farther down underneath the concrete, if i drill a hole all the way through i'd hit dirt or gravel. If i stop short the hole would be maybe 3" deep, is this deep enough, or does it give the umbrella pole leverage enough to crack the concrete? Or would the umbrella pole just bend?
Another concern would be what would i do if i hit rebar? Can a diamond drill bit drill through rebar? (that would suck, off by 1/2")
