The mortar on my last patio job in Springfield started failing after just one winter, and I'm trying to figure out why.

I think the supplier's pre-mix might have had too much lime for our freeze-thaw cycles, so I'm going back to mixing my own from scratch with a different sand source.

Just one winter? That’s brutal.

What kind of mix ratio were you using before? I had a similar issue on a walkway project where the pre-mix just didn't hold up to the cold. Switching to a sharper sand and cutting back on the lime made a huge difference for me.
