This page is the first in the area 'Facing Masonry'. It is typical in such facades that stones and joints are visible. But where should the brackets be fixed, in the brick or in the joints? What about stone joints that are not flush with the wall? These issues are addressed here before going on the next pages to different brick types.
Normally, for reasons of strength and support, steel cables or trellises are mounted directly into brick/stone. Only in exceptional cases, and also when reservations about drilling into the bricks exists, it then must be secured in the joints (cemented seams). As is known, joint mounting is often favored.
Theoretically, joints have the same strength as the built-in bricks/stones. On “new” face masonry joint mounting holders are therefore usually not a problem. The often old and crumbling wall joints are challenging because cement was once precious and was reticently mixed with grout. Over the course of decades, weather and washouts played a role. And behind an intact, hard outer layer, joints can often be crumbly, and therefore have limited viability. Then you need a pre-treatment, for example, i.e. with the respective plastic anchors or the wall bracket that are glued directly with composite mortar. Details can be found in the individual stone types section.
The 'offset' of joints can be problematic. Joints can be flush with the bricks, protrude, or be indented. Due to the offset surfaces, it may cause a non-uniform pressing of the rubber seals. Therefore, a joint offset should be as balanced as possible, either by sanding a protruding joint or by building a larger contact surface, in turn, using composite mortar. Also remedy by fitting cut and set pieces from weatherproof rubber bandages.
