Hi
I suppose to overlay a new concrete slab with 4" thick (each 12' x 20' panel) on the exisitng cracked one with 6"-8" thick. Since the existing concrete slab provides very rare contraction joint,my question is how can I reduce the risk of differential contraction and restraint force due to friction against the exsiting slab when I provide more joint in the new slab. Will plastic membrane work?
Thanks
