Supporting heavy weights
Where very heavy furniture and timber used for construction purposes are to be attached to solid walls, expanded masonry bolts should be used for secure fixing. These are inserted into a suitable hole and, when the bolt is tightened, it draws a plug up into the outer body of the bolt, which then expands and grips the masonry. When positioning the holes, avoid drilling in the mortar between bricks and in the corners of the bricks themselves.
Heavy fixings
Lined walls are obviously weaker than solid ones, and great care must be taken when fixing up heavy objects. If there is too much stress on an unsupported wall board, it could rip away from the studs. To make a secure fixing, locate the timber studs and attach a batten to the surface of the wall. The object can then be screwed to the batten.
