Topping for Existing 6.5" Slab-on-Grade
Topping for Existing 6.5" Slab-on-Grade
(OP)
Hello everyone,
I've got an existing 6.5" interior slab on grade that I would like to add a 4" topping get additional capacity for heavy wheel loading.
What are some of the general considerations to get increased capacity in terms of mix, reinforcement, surface preparation, dowels, etc.
Thanks in advance,

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Wire mesh was picked up by the GPR at 6" o.c. near the bottom of the slab.

Some time later core out some samples. Take a chisel and try to break them apart at the joint. My bet is that none will break at the joint.
