Repairing a stone foundation house dating back to the 1820s requires careful consideration of the historical value and construction methods of the house. Here are some options for repairing a stone foundation:
Lime mortar: Traditional lime mortar was commonly used in the 1800s for stone masonry. If the foundation has areas of missing or deteriorating mortar, it is important to use a lime-based mortar mix to maintain the historical integrity of the building. Lime mortar has the ability to flex and move with the natural shifting of the foundation, reducing the risk of future cracking and damage.
Waterproofing: Older stone foundations may not have been designed to prevent water intrusion, which can lead to moisture problems and deterioration. Applying a waterproofing treatment to the exterior of the foundation can help prevent water from seeping through the stones and into the basement.
