curing shotcrete W. PICTURES. Now found CRACK

[aniceone]

What do the samples look like - are they cores and did you get pictures - the contractor should tell you how is going repair the side - a good bond is needed so it will not delaminate latter - the contractor is trying to run over you , stick by your guns - you have the California Building Code on your side also the American Concrete Institute -Guide to Shotcrete 506
I feel you pain

I missed the time when he took the samples - I doubt he did a very thorough job, and it did not sound like they intended to repair the side (they are more concerned with repairing other various issues the masonry guys discovered, although it makes no sense to be sticking masonry on a faulty shell).

Of course they are trying to run me over ...
