I am looking to replace a home driveway, patio, and connecting
walkways, and am gathering quotations. I am posting here to ask for
help with several items:
1. Is a concrete job ok to perform at this time of the year in the
northeast U.S., starting next week, where daily temperatures are in the
60's and night-time lows can be possibly be in the low 50's, maybe high
40's? The job supposedly will be completed by the end of next week.
2. Is a 4 inch thick, 4000 PSI, 6-1/2 bag mix with 10/10 gauge mesh a
reasonable method? Should I consider asking for 5" or thicker, more
cement bags per yard, heavier mesh, etc.?
3. Expansion joints using 1/2" fiber "as needed" are being offered.
Should I insist on expansion joints every "X" number of feet instead?
The climate here is well below freezing in the several months of winter
and in the high 80's in the warmest months of the summer.
4. The job calls for about 2600 square feet of concrete, about half for
the driveway and the remainder for a large patio and 3 walkways. A
rough guess is 27 yards of concrete to be installed after removing
existing concrete, compacting the base, pouring gravel as a sub-base
and then installing the new concrete. Any wild guess as to what a job
like this should cost?
I would very much appreciate any other thoughts or suggestions as well.
Thanks very much for help and suggestions.
