Diekamp lab - Development of building materials for use in heritage conservation (NHL modular system)
In collaboration with local restorers and building material manufacturers, a modular system based on natural hydraulic lime (NHL) has been developed for the restoration of natural stone masonry. A basic recipe can be adapted for all major applications (masonry mortar, pointing mortar, sacrificial render / poultice plaster, render) by slight modification of the recipe. Research into the scientific basis of the NHL system is ongoing.
