From the study of the ancient techniques of building, formulation and production of specific materials for historical, archaeological, monumental restoration and sustainable construction.
Calchèra San Giorgio Research and Formulation Center studies and produces specialist materials for restoration, structural consolidation and renewal of buildings of historical interest. Our focus is developed according to project requirements, historic building techniques and local traditional materials which characterize the physical quality of the structure and its associated culture.
Every material we produce undergoes a production control, and meets CE marking certification, in compliance with Safety Requirements and EU Guidelines.Some of the raw materials used in our formulations are:
Pantheon Pozzolanic Lime Mortar was developed and produced throughout the years. Its formulation was obtained after a thorough investigation of Roman mortars found in the extraordinary and enduring momuments studied, and is the synthesis of all binders described in historical records: Calx intrita, pulvis baianus, testa tunsam, pumex, sabulum. This ancient but futuristic binder is perfectly compatible with any ancient historical structure, and is extremely versatile in the preparation of formulated mortars. It contains neither water-soluble salts, nor free lime, or any form of clinker, or other inaccurate material, as expressed in the “Rule of Art”. Pantheon Pozzolanic Lime Mortar is designed and produced by the Calchèra San Giorgio, and is the basis of all hydraulic-setting mortars employed in the composition of powder compounds.
