Description: The company NANOSHIELD is a young technology-based company, born by a group of doctors from the University of León and the CSIC, who joined forces to respond to the challenges offered by the heritage. We design products to protect stone assets in a professional way (developing international patents) as well as evaluate existing products on the market, with our environmental testing laboratory. The company can also provide the most suitable products for each need, with our waterproofing consolidant as the star product, or recommend other existing products on the market (waterproofing, anti-graffitis). We provide training and certifications in the applicability of these products. Additionally, we offer other related works of interest, such as 3D surveys or salt maps or map the deterioration patterns of the monuments. Last but not least, we have developed our own vulnerability tool to prioritize the most urgent actions for managers of a large number of monuments. We are experienced consultants in a wide range of disciplines because we are formed by experts in different related areas: geologists, physicists, chemists, materials engineers, and restoration architects, which allows us to help companies that need to address heritage challenges.
