That talk with a structural engineer about concrete shrinkage made me nervous
I was pouring a 30-foot driveway last Tuesday and an old structural engineer stopped by, said he's seen too many slabs crack because finishers didn't account for shrinkage after the first day. He told me 'most guys seal too early and trap the water inside, then wonder why it spiderwebs three months later.' Has anyone else gotten advice that made you change your whole finishing schedule on the spot?

Hate when some random pro drops wisdom that makes you rethink everything mid-pour. That's rough but better to know now than after the slab's shot.

I read once that waiting 24 hours before curing can cut shrinkage cracks in half.

Yeah waiting that full 24 hours makes a huge difference in my experience. I let the concrete sit under plastic and just mist it a couple times before starting the wet cure. Have you tried using a curing compound instead of relying on timing alone?
