I just wanted to get opinions on my plans to fix the somewhat sunken slab in our garage.
We bought the house two years and (it's about 50 years old) and I have been monitoring the slab since day 1. It has not sunk any further so it's likely that the settling happened a long time ago.
Anyway, the slab is about 2" to 1" lower than where it should be and I am considering the following two options:
Add a thin layer on concrete and then install basic by 4/5 PEI rating porcelain tile.
Add the concrete layer but top it with 1/2" interlocking vinyl or PVC tile.
The reason go with the porcelain or plastic tiles is basically to avoid the thin concrete layer from peeling or cracking. Btw, I do intend to drill holes every few feet and use some bonding additive to help the two layers of concrete bond.
The question is, will either of my options work?
