Natural Dolomitic Binder - LDN

‘Legante Dolomitico Naturale’ is a natural aerial binder without chemical or cement additives, meant for the preparation on-site of biocomposites belonging to the Bio Beton® line by Senini, suitable for the restoration of historic buildings, renovations, new buildings and for the emerging need to build ‘Nearly Zero-Energy Buildings’ known as NZEB.


Acts as a binder for the production of bedding mortar and for the insulation systems of: masonry walls, external/internal walls, roofs, attics and subfloors. It’s also used for base and finish coating systems, in architectural restoration and in Neo-building.


‘Legante Dolomitico Naturale’ is mixed with hemp shiv following specific ratios, thus creating ideal biocomposites for plasters, insulating walls, external insulation and substrates. ‘Legante Dolomitico Naturale’ stabilises the hemp, which in turn, thanks to its silica component (about 5%), hydrolises the high content of aerial lime. Mixing both elements protects the biocomposite from fire, decomposition, or aggression by rodents and insects. The hemp enhances all the characteristics of natural lime by increasing its porosity, breathability, permeability to water vapour and the ability to manage the humidity in the living space. Hemp shiv also add workability and structural body, allowing to coat vertical walls with a single application of thermal plaster, for a thickness of 1 to 45cm.
