Masonry base material 7.1 General suitability The direct fastening technology can also be used on masonry. The joints between bricks or blocks and the covering plaster layer on virtually all types of masonry (exception: lightweight aerated concrete block) provide an excellent substrate for light-duty and secondary fastenings. Suitability table: DX fastening on masonry Masonry material Unplastered masonry Plastered masonry Fastenings Fastenings Fastening in mortar joints* in masonry in plaster (joint width ≥ 10 mm blocks or bricks (thickness ≥ 20 mm) Clay brick solid ++ + ++ vertical perforated ++ – ++ horizontally perforated ++ – ++ Clay clinker solid ++ + ++ vertical perforated ++ – ++ Sand-lime block solid ++ ++ ++ perforated ++ ++ ++ hollow ++ ++ ++ Aerated concrete –– –– –– Lightweight concrete solid ++ – ++ hollow ++ – ++ Hollow concrete ++ + ++ Slag aggregate solid ++ – – perforated ++ – ++ hollow ++ – ++ ++ suitable + limited suitability – not fully investigated –– not suitable *) Joints must be completely filled with mortar The above table is based on laboratory and field experience. Because of the wide variety of types and forms of masonry in use worldwide, users are advised to carry out tests on site or on masonry of the type and form on which the fastenings are to be made. 1.64 11 / 2<strong>00</strong>7
