Slippery concrete cause?
Slippery concrete cause?
(OP)
Hi, this is from an occasional client requesting an opinion on something I was not involved with.....
" This is new concrete at the main front entry that was installed by our remodel contractor less than 1 year ago. We get a good amount of snow and the concrete becomes VERY slippery even with salt. The GC seems to think the discoloration and slipperiness is due to our use of concrete salt! I know this is not the case and I feel strongly that the concrete was not installed properly. "
It is a well traveled restaurant. And she is seeking some understanding. I really don't know. I would sure appreciate any insights you might be able two share. Thank you.

The restaurant should either add some non skid surfacing or tear it out and redo it. They should do it today. While they're arguing with the contractor someone is going to break a hip.

Concrete can be finished to a mirror shine. It almost never should be.

Recommend abrasive grit blasting (Blastrac or similar).

Agree with Ron's suggestion. Lightly shot-blast the surface.
Or apply a non-slip surface material.
Continuous application of salt will take years to produce the rough surface suggested by ztenguy.
