I have a concrete patio that consists of 4 sections, about 10 feet square
and they are slightly shifting to create 1/2" spaces between them, and the
foundation too. (you can't see how far down the crack goes. seems deep)
I had a tuckpointer here, and he mentioned that besides the work I
called him about, he could fix this as well.
As you can imagine, constant rainfall and freezing weather washes away dirt
the slabs, so over time I'm afraid this will get worse.
The house (and maybe the slabs) are about 50 years old, and we live in the
over clay soil. There is other evidence of shifting soil around here.
The tuckpointer said he'd use hot tar to seal things up in between the
I wonder if that's a reasonable fix, or if I could use another material,
myself, to get a good result.
Would silicon work in this situation? Other sealants?
