I will still thicken the concrete below. For drop in anchors to be set properly, they should be set 1/8-1/4 below slab. The anchors we use in 5/8 size are roughly 3'' long. The average garage slab is 4-5'' thick. Concrete poured years ago weakens over time. Its very difficult to tell how strong older concrete is and you see alot of slabs have cracks throughout. I like the system but I wouldnt trust my slab.

What about the portable one Rob posted a while ago? and its goes to full height and it was 1/2 as much.

 

I dont think i saw that thread :confused: I like the idea of this one because it can fit in a garage with 8ft ceilings and not put a car through the ceiling.

I thought that standard res slabs are 3" thick. Also concrete has a 50 year life span on the grades used in resedential applications. It should keep getting stronger and stronger as it ages till 50 years.

Umm no. I have torn out plenty of slabs after only a year. Commercial slabs are sampled and tested. These are the slabs that are usually covered under a normal warranty. Asphalt can be layed at 3'' thickness. I have seen 4'' thick slabs but I wouldnt recommend anything less than 5''. There are alot of factors which goes into properly laying concrete. More than the average guy will ever do/consider.
