Since the characteristics and composition of natural stones, mortars or concrete may vary greatly, an in-depth knowledge is required to take further measures. Next to the tracing of chemical-physical parameters, the mapping of construction materials can be a useful addition to the documentation of the structure and, in conjunction with damage assessment, is a crucial precondition for the evaluation of the building condition. In many cases lack of barriers or defect outflow leads to moisture penetration of the masonry.

Unforeseen dampness causes salt efflorescence, that, dissolving and crystallizing periodically, wears down plaster and masonry. When working out a sustainable restoration concept, the analysis of causes and mechanisms of damage is a matter of course to us. In order to, for example, rule out expansion effects after the redevelopment, the decision for the conceptual implementation is based on specific knowledge of the chemical and physical interaction of building materials and their components.
