Stone foundation and compatible mortar
Repair stone, joints and moisture in an older foundation without automatically applying overly rigid modern mortar or trapping moisture.
VERT / GREEN
Map friable joints, loose stones, water and deformation before cleaning/repointing.
JAUNE / YELLOW
Repair mortar must be compatible with original masonry; maximum strength is not the same as durability.
ROUGE / RED
Bulging, loose stone, deep mortar loss, major water entry or underpinning: competent mason/engineer before cosmetic repair.
Useful tools and data
- Photos/moisture log
- Old mortar sample
- Exterior drainage plan
What the professional checks
- Identify stone/mortar
- Assess stability/deformation
- Select compatible repointing
