Our cellar was tanked a number of years ago using a waterproof membrane, and the walls were subsequently plasterboarded/plastered over. I now want to put up some shelves but am unsure how to fix to the walls without compromising the integrity of the waterproof membrane. I know there are special plugs that can be bought for fixing the membrane to the walls, but how do you go about fixing through plasterboard and the membrane?
thanks, Andrew

you can buy redi drive fixings or umbrella fixings that will just fix through the plasterboard try screwfix.com
