Tattling to the permit office is a real good way to not be swimming until 2024.

Only reason we still put steel mid slab in city street pavements is because we are using seriously out of date technology.
Great post, btw…thanks for your insights/observations.
A pool slab isn't designed for that bud...Mas89 said:" Tensile loading on your slab should be low".gotsand said:
What answer could he possibly give that's reasonable? The chairs are just for show to the City inspectors, but they aren't really necessary as tensile loading on your slab should be low.
Even if that's true, "It'll be good enough." should not be good enough, but slippery contractors love to play that hand.
I would not assume that. What if a large tree needs to be taken out with equipment or a mini excavator needs to dig somewhere and access is only across that slab? Lots of reasons to do the job right. A small skid steer has had to access my yard over the pool decking several times over the years.
That is the same horse**** I felt like it was when I heard it while taking bids over the last year on a pool.AGGIE WH08P said:
Well, heard back from pool contractor. He was able to confirm that they will give us a lifetime warranty on my concrete. He mentioned that they already offered a lifetime warranty for any mayor failure (more then the minor cracks).
Of course, my first though was how good is a lifetime warranty if this company isn't around in 10 years. Who knows. I'm going to get everything in writing to be safe.
Just out of curiosity, did you used to work for an O&G company in Houston, and are friendly with Lorenzo?agcivengineer said:BoerneGator said:Please elaborate. Do you mean to suggest that the huge amount of rebar installed in the miles and miles of concrete interstate hiway are unnecessary?Quote:

There are 3 concrete pavement types found in the USA: Jointed reinforced concrete (JRCP), continuously reinforced concrete (CRCP), and jointed concrete pavement (JPCP).
JRCP is common for parking lots and city streets in Texas...and is not really recommended anymore by any organization, nor is used by any DOT in the country anymore. This is the pavement that has #3 or #4 rebar at 18" on center each way and then expansion joints every 80' or so. This pavement is hard to maintain and water infiltrates the expansion joints causing erosion problems and other issues, plus is noisy and hard to build a good ride. Random cracks can form here and deteriorate over time because there isnt enough steel in it. However, its standard and hard to change.
CRCP has 10 times the amount of steel compared to JRCP, but doesnt have expansion joints, will crack due to rebar about every 5 - 10 ft, however there is enough steel to keep cracks tight, and is standard on Texas highways. This is a very good performing pavement (probably the best), but is expensive and slow to build, however doesnt require much maintenance, hence great for heavily trafficked roads.
JPCP (TxDOT calls it CPCD) does not have steel in mid slab, but does use smooth dowels at transverse joints to allow for movement while transferring load across the joint and tie bars (rebar about 4' long spaced every 24') along the longitudinal joint to prevent slab migration. There are no expansion joints in this pavement. This is the standard concrete pavement found across the USA in all DOT's and cities except in Texas.
If yall are curious, i do teach as an invited industry advisor to the senior CE Capstone design class at A&M every semester, and my father is a also a professor in the CE Dept at A&M.

I kind of feel honored that in 13 years and thousands of threads on TexAgs, mine got you to speak up!! Greatly appreciated!!
One on the pool contractor owners came out today. He agreed that it wasn't right. He said he would visit with the concrete company and see about getting a 10-20 year warranty.
Make sure it's a 3rd party warranty. Otherwise it's not worth anything.
