"READY TO POUR."
I've been doing some homework on the web and by asking other concreters. Here's what I've discovered:
When there's no formwork and the area to be concreted is as large as ours, concreters establish
reference points
over the area to make sure that the thickness of concrete stays uniform.
These reference points can be as simple as many pegs driven into the ground in such a way that they stick up by 100 mm above the levelled crushed rock base. When they pour the concrete, they simply make sure it comes up to the top of these pegs.
Concreters use as many of these as necessary - it varies depending on the slope of the site etc.
If Mr Murone had finished our driveway ...
NEW CONCRETE WOULD LOOK GREAT - CLEAN, SMOOTH.
BUT WHO KNOWS WHAT'S UNDER IT?
IT COULD BE JUST SMEARED THINLY OVER AN UNEVEN BADLY PREPARED SITE.
HOW WOULD I KNOW?
Until it rained and puddles formed.
Or until I drove over it and it cracked.
Or until the next 40 degree day
Or the next frost ...
Or until any stress was placed on it.
