Hi,

The slab in my detached 2 car garage (soon to be woodworking shop was really badly heaved and cracked (no rebar and only 2in thick in spots). A few weeks ago the slab was cut about 6 inches from the sill and broken up, hauled off and repoured by a concrete company. The new slab has #3 rebar, 12" on center, is 5in think and was tied into the old so I shouldn't end up with a floor like before.

The floor looks great and is pretty level throughout, however when I closed the right garage door I noticed that on the right hand side of the door there is a slight downhill slope. This causes about a 1.5" gap on the bottom right side of the door when the bottom left side is fully touching.

I've got a couple of ideas, but the one I am leaning towards is to scribe and cut a 2x4 to the contour of the slab there and then attach it to the bottom of the door with lag screws (it's a metal door). Then I can paint the 2x4 strip the same color as the door and add the drip edge back.

Thoughts/ideas?

Thanks a lot.
