Minimum thickness for concrete pour
Minimum thickness for concrete pour
(OP)
Is 1" too thin a thickness for concrete slab on grade (using fibermesh)? It's an odd situation, the pour thickness slopes from a 3" at one end to 1" at the other with aprox 4 ft width across. The pour is going to be on top of an existing concrete floor (basement underneath). The concrete floor has been roughened to a ¼" amplitude. The pour being suggested is 3/8" chip mix with 5" slump and no fly ash (all cement). The floor will get tiled or carpeted eventually.
So is 1" too thin a thickness to pour?

The best "chemical bonding agent" is Portland Cement. With the other stuff, there is too much chance that it will act as a debonding agent.

The topping may actually be 1"-1/2" thickness and now I am wondering if I should just have them use non-shrink grout.

A portland based sand/cement slurry can be an effective bonding agent as long as the surface has been prewetted (no ponding water) and is scrubbed into the surface. For thin cementitious toppings I am a fan of matching the properties of the base slab.
