What is coch slab?

Been around a long time and never heard of such. Care to define a bit more?

This was the only place I could find the words coch and slab used together:

I have never heard the term either.

Ty Coch was a man but you are asking a cement question, I believe. Are you sure of the spelling, possibly coach

Seems to be a process/machine for finishing slabs.
