Repointing the Stone Foundation and Patio

19 photos · siding and exterior

The original fieldstone foundation was losing mortar and the concrete steps had pulled away from the wall, so water was running straight in. I had a surveyor pin the lines, brought in a small excavator to dig back along the wall, repointed the stone with fresh mortar, set a gravel drainage bed, and patched in slate to fix the flagstone patio that had broken up around the planting beds.
