I think the best thing is if we see a mat a the lower level of the slab and at the upper level. That, and drain system element placed where it did not thin the slab, are the most important features in the slab field. Jointing is being more closely placed, which will help with shrink cracking and how far joints open as the slab cures. Joint construction is important because sealant deteriorates in all cases. Possibly we will se a waterstop crossing the joint.
Watched “Deepwater Horizon” the other day. Kurt Russell (rig boss) asks Mark Wahlberg if he brushed his teeth and flossed this morning. Said, “It saves a lot of money and pain in the long run.”
Good advice regarding preventive maintenance vs fixing a problem later.
The lesson has to be taught over and over, it seems.
