but the real question is has anyone done it one a hollow blocked walling?

even drilling on the wall will somehow wreck or cause a crack... shocking.gif

I done before. My office building is using the hollow brick.

You need something like Terence573 mention. But bigger size to grab wider space. If you consent about the weight of your cabinet, drill extra hole instead of standard.

Even you use the plug, it may need proper strengthen to hold cabinet. Kitchen cabinet is not light.

Just drill more hole to hold. If 4 hole hold 100kg = 25kg each hole. 8 hole will hold 12.5kg each hold.

That will lighten the hole stress and possible crack. But still can hold a 100kg weight. Makesure each hole pitch is wider.
