One wrong mortar mix can shorten the life of a historic wall.
On heritage buildings, selecting the right mortar is one of the most important decisions in the restoration process.
Modern mortars are often harder than the original brick or stone. When that happens, moisture can become trapped instead of escaping as the wall was designed to, leading to cracking, spalling, and premature deterioration.
Heritage restoration begins with understanding the original materials and choosing a compatible mortar that allows the building to perform as intended.
Sometimes, the materials you don't notice are doing the most important work. 🧱
