Placing concrete has traditionally involved setting up a series of wooden boxes and then concrete is poured into alternate sections.
After the concrete has dried, the boxing is dismantled and a new load of concrete goes into the sections missed the first time around – hence the name ‘hit and miss’ pouring.
While this method of pouring concrete is well-established and fairly straightforward, the process has always had drawbacks. A major issue is the amount of time it takes – because you’re being forced to sit through the drying process before you can pour again. Cutting control joints into the concrete with a diamond saw adds more time on top this.
