2" concrete fill over existing SOG
2" concrete fill over existing SOG
(OP)
Existing construction with 5" concrete slab on grade with 2" mud-set tile. The mud set tiles were removed for a portion of the new slab due to some new work and the question now is how to infill back the 2" with new concrete. To me it appears that the 2" is similar to non-structural topping over precast planks. I don't see any issues with providing such a thin topping granted we specify welded wire mesh and control joints at 15' max.
Is 2" too thin of a topping over existing slab?

1. Scabble or otherwise roughen the entire surface of the existing slab.
2. Carefully clean this roughened surface.
3. Wet-soak the roughen surface for 24 hours.
4. Place the 2" overlay (plain concrete, no wire mesh).
5. Wet cure for 7 days.

Wet curing is a necessity for a bonded overlay, in my opinion.
