Why lime mortar?
Why lime mortar? In a nutshell, for a stone foundation or a historic brick wall, the mortar should be the sacrificial layer. Erica, a follower on Instagram who works in the preservation field, used those exact words, and it was an aha! moment. Specifically, water always seeks the path of least resistance.

Repointing is maintenance. Rebuilding or replacing a foundation or brick wall from scratch is not.
