Re: is concrete supposed to breathe?
I just did two houses a while back on the same day with commercial concrete grinder. I hooked up our large Ridgid Shop vac to the outlet port, installed a Hepa Filter, and had virtually no dust at all. We did have to replace the Hepa a few times, (we anticipated this and picked up extras) The only complaint was the exhaust from the 10hp engine. Solved that by breaking out the 42" floor fans, and wearing one of our full face mask respirators.
