I had 18 yards of a driveway poured yesterday. Two 9 yd trucks. 1st truck came at 11, 2nd tuck just before noon. 85Ã‚°, not too humid, beautiful weather for here.
The ground we poured on is undisturbed, harder than rocks after being driven on for a year. The very top is dusty, clay-like stuff that turns to elephant snot when it gets wet.
Around here, drives are usually poured on the ground, 3000 psi, no wire, no plastic, no fiber reinforcement, no cracks.
Finishers ran control joints across the 10′ drive about every 10′.
When I got there this morning, everything from the 2nd truck has cracks running the length of the drive, except one place where an inside curve starts, and probably should have had a control joint, but I’ve seen plenty with the same situation that didn’t crack.
5 gal of water were added to each load.
Concrete company says the ground was too dry, sucked the water out… should have run plastic, or wet the drive.
7 other drives have been poured in this subdivision at all times of the year, no special prep, no plastic, no fiber, no wire, no cracks. As a matter of fact, I’ve never seen plastic used in a drive, and wire and fiber only when there’s fill or sketchy dirt
Finishers say they got no idea. Never seen this.
The control joints were not especially deep, maybe 3/4″… the other drives have a bit deeper ones. Finishers used a window pane tool with joint groover on the bottom, so I assumed it was deep enough…, but I had them cut the rest of the joints on the good panes deeper today.
Tomorrow finishers will cut through the slab where good meets bad. They don’t have a way to get the slabs out, so Mon I’ll get my excavator to dig them up and haul them off.
Concrete company could do a core test on the cracked slabs but it’ll take 28 days, and might cost 2000 bucks. If it’s wrong they’ll eat it.
They’ll also give me the 4 yds we’re ripping out, for good will.
What I’d like to know is:
has anybody seen this phenomenon, is it even a phenomenom?
How would you deal with this responsibility-wise and money-wise?
