Sawn joints spalling
Sawn joints spalling
(OP)
What are your ideas and experiences on why the edges of saw cut contraction in a slab on grade are spalling off. My thought is the joints were cut too soon. The rest of the slab looks good but almost all the joints look like the attached picture.

I will admit however, that I have only seen streets cut with a softcut saw. Never seen a slab on grade cut that way, so I cant comment on the effect of burnished finish.
