Sure would appreciate some advice.
There's a 1/2 basketball court (20x25) made out of 2x4 slabs of concrete poured about 80 years ago.
Over those 80 years, the slabs have heaved and moved, with very very little cracking. The difference in height between them is at most 2", but most are less than 1"
I'd like to be able to do this job inexpensively, but well so that it lasts for years.
Could I put a 4" slab down right on top of this, with a mesh inside?
Vabor barrier? Foam between slabs? Sand between slabs? Rebar into old and new slabs to connect them?
Thanks very much,
