scarificial slab
(OP)
I'm working on a slab for a high wear application. My idea is to cast a slab on grade to handle to load, then cast a 4" sacrificial slab on top of this to serve as a wearing surface. This way, when repair is required, the entire slab does not have to be removed, only the top layer. Any suggestions on do's and don'ts for construction? I intend to spec a polyethylene sheet between the two slabs as I don't want the two slabs to bond.

The plate scenario I've considered but never given a whole lot of thought to it. But now I'm interested. How would you anchor the plate to the slab and cover every inch of concrete? What about heat build up in the summer and heat caused by friction between the bucket and the plate? I'm concerned about buckling.

Depending on your client’s expectations for longevity, a lightly-reinforced sacrificial slab, separated by a polyethylene sheet from the “structural” slab, could be the most cost effective solution. Patch repairs could then be made as required.

This can give an extremely hard wearing concrete.

Don't leave something for the future wishing they will take care of the maintenance. Nobody does.
