plaster walls with no studs. pyrobar
i want to put up a big shelf that will hold some heavy items. the problem is my walls are made of plaster blocks called pyrobar. they blocks are stacked one on the other and held together with mortar. any ideas how i can anchor the shelf?
i found this picture online of what prybar looks like for those unfamiliar. http://1.bp.blogspot.com/_62NH2bo0YhQ/SgDhaAdO7wI/AAAAAAAAALQ/zpoEBb3foKE/s1600-h/S6304484.JPG
