Responsible Heritage Protection Actions

In recent decades, interest in maintaining and conserving cultural assets has grown and there has been greater investment in the conservation of historical heritage. Developing a good methodology for action is key to guaranteeing adequate preservation of cultural assets. With this in mind, the Spanish Historical Heritage Institute convened a conference in 2002 to try to define basic criteria to guide the different phases of the intervention process in stone materials in all stages of stone conservation: cleaning, consolidation and protection. Carrying out efficient protection of monuments in the traditional way focuses efforts only on how it affects the property, but not on the collateral impact it may have on the environment, or how the effects of climate change may alter its functionality. Thus, a more multidisciplinary test design is needed, with a mandatory laboratory simulation phase under simulated rainfall that represents the increased environmental aggressiveness expected in the near future due to climate change. Hence, water becomes a means to simulate these future conditions, but also a way to explore the effects on rivers and groundwater near the points where the monuments will be treated. Since fresh water is one of the resources that is expected to become scarce in the short term, we intend to carry out responsible tests that take into account both aspects: saving water use and water pollution. Combining the conservation of monuments and environmental responsibility, it will be shown how it is possible to carry out research to achieve a natural product that serves as a sustainable coating for monuments of stone material that is durable but that reduces the environmental impact both in the selection of the product and in the experimental phase, as well as in its operation after application.
