I aim to fit a (fairly heavy) kitchen wall cabinet to a plasterboard wall. Behind the plasterboard there does not appear to be any studs. So I guess the plasterboard (what I would call drywall - plasterboard with no studs) has been glued to the brick exterior wall. The cabinet once fitted will be laden with lots of heavy pans etc.

Can the plasterboard be drilled through and into the brick wall behind it? What type of plugs / fastening would be recommended?
