Building with factory-prefabricated masonry panels made of clay units meanwhile has become a long-established, field-proven construction method. The advantages are shorter construction time for shell constructions, lower construction costs and uniform level of quality as well as high dimensional accuracy of the masonry panels and a production that is independent of weather influences. An innovation in the field of prefabricated masonry is the dry bonding method for prefabricated masonry panels made of clay units whereby, instead of a conventional thin layer mortar, a two-component polyurethane adhesive (2C-PUR) is applied by machine to the flat ground surface of the clay unit.
