Cabinets having only shimmies to support them... common practice?
My GC hired a subcontractor to tile the floor for my kitchen remodel. He only tiled what was necessary and what will be visible (ie. the entire border area of the kitchen is not tiled). The cabinets were installed today; however, since the floor is uneven (tiled area is higher than untiled area), they've used shimmies to make the floor even. Which means, the back half of all the cabinets are basically sitting on thin air... and shimmies! Is this common? My GC assured me that it's how they've always installed cabinets. The kitchen I used to have before the remodel, had tile the whole way through before cabinets were placed on top. Will the shimmies be stable enough to handle the cabinet weight + granite weight + weight of appliances and anything I put in the cabinets?
