I'm FINALLY $$$$ putting in new concrete floor in my new 30x60 garage. I'm using 4000 psi non air concrete with fibre. I'm letting it cure 28 days,been hosing it down with water. Now the question my 2 engine cranes I built welded 55 yrs ago heavy duty from hd tubing.ive picked up diesel engines with the one, the wheels are steel 4" should I replace them with rubber or some other material. Or I'm I just thinking to much about floor damage? Concrete from very good source. Tech very good as I was the inspector there for 15 yrs. No price break for me.
