Fixing cupboards to wall in garage. General problems, solutions, information and advice on fixing to walls of all kinds

Hi all!

I'm getting desperate here. I am trying to figure out a way to attach some heavy cupboards to an extension garage wall. The problem I am having is none of the fixings I use will get tight to assure the cupboard doesn't drop onto my car.

I have experimented with:
* Large screws and rawl plugs, these just spin and pull out.
* I tried 100mm double glazing fittings, but the screw just pulls the plastic end bit right through.
* I tried 110mm rawl bolts, but again, these don't get tight.

It would seem the concrete blocks the builder used are made of corn flakes, and then there is 1 inch of plaster board depth, not including the 3/4inch MDF of the cupboard. There is a cavity just after the blocks, but that is 150mm in after all the layers.

How do I fix something heavy to these walls?

Thanks in advance for any help given,
Toni.

Never mind, going the chemical route...

you can use 120mm stardrive fixings,You drill a 6mm pilot hole and the screw drives straight into the block eliminating the need for raw plugs you will need a strong cordless to drive the screw home.
