Re: 2 post lift near shrink cracks??
What's the slab sitting on? Sand, gravel, rock? Mine sits atop 20ft of blasted ledge, I had 1 crack in my 6 inch thick floor, I put my lift in, bolted it to the floor, and I had to bolt shallow as I have a heated floor. Holds my 07 cc duramax about half way up. I'm to chicken to go higher. Lol
But id have the guy that poured it back to take a look, that's slot of cracks.
