Get something like this. The inner end will expand and grips into the other side of the wall.

You do realise that each of those plugs hold 10kg or more

What I had posted is the more expensive version of butterfly plug. Same concept except the anchoring on the other side of the wall is much more significant. Used them a lot for plaster boards mountings.

If your bricks on the wall crack its either its such a poor construction you have other things to worry about or the drilling is not done properly. Not sure what can be done by your contractor but perhaps installing a decently thick backing board onto your wall where the cabinets are then mounted onto? Only your contractor can tell what is feasible.

And yes, mounted pretty heavy stuff using these plugs onto ceiling boards. The plugs will hold itself for sure. Your issue here is whether the wall is designed to hold the kitchen cabinets which once fully loaded are heavy.
