MORTARS,RENDERS+PLASTERS
Essential to the composite structure, mortar contributes to the building's longevity, authenticity and aesthetic.
Acknowledging every building as unique, Calibre's conservation strategy starts with an understanding of the physical and chemical properties of your mortar and its substrate. This informs appropriate specification, materials and practice.
