Historic old homes constructed of rock and lime based mortar are deterioration at an alarming rate, crumbling mortar, shifting rocks are some of the signs of a fieldstone foundation in need of repair. Over time water and moisture will break down and wash out the lime in the mortar leaving piles of sand around the perimeter of your basement.
This is mainly cased due to the fact the exterior of the fieldstone foundation; below the grade of land there is no mortar. All the mortar that supports your old stone foundation is packed from inside the basement and also on the exterior, above the grade of land.
Homeowners that are doing landscape project around the house, digging against the foundation or removal of shrubs and bushes will often notice when its raining the will experience water in the basement. Disturbing the soil around the fieldstone foundation will uncover the below grade part of the stone foundation exposing the open stones and allowing water to enter. The most important thing to remember is disturbing the soil against a fieldstone foundation could cause structural problems.
Look around at other homes and there fieldstone foundations you may notice that parts of the stone foundation are actually block wall or poured concrete. These are structural repairs, which cost the owner tens of thousands to do. Foundation failure? Once the large stones within the foundation fall into the basement or bowing of the foundation starts, its impossible to break it down and rebuild the stonewall in the basement. You now have to hire a structural engineer, a foundation installation company to structurally support your home.

Your home is as stable as the foundation it sits upon. Don’t just let anyone work on your foundation
On some fieldstone foundations’ you’ll notice a white coating or plaster type of material on the stone walls in your basement, this is a method of waterproofing a fieldstone foundation called white washing or lime washing. This slurry coating not only brighten up the basement but also preserves the mortar allowing the fieldstone foundation to last even longer. Many masons, historians and foundation repair companies go back and forth about white washing, some claim it does more harm than good others disagree.
