Sounds like I maybe should get the floor torn up and get it re poured again to a 4" slab with fibre through it. Or sell the lift and go back to crawling under everything again...
Ready to install a 4000kg 2 post car lift and the concrete is too thin and not the correct psi
Is it better to have 2 pads cast at 4 wide x 5 long x 2 feet deep for each post
Or
4 wide x 16 long x 1 foot deep spanning the two posts
Not sure what is under the existing slab but I think it...
