Good morning everyone... I recently bought an old New England Farmhouse that I traced back to at least 1820. The foundation has a variety of "issues" that I want to address right away and I am looking for helpful advice/suggestions from anyone who wishes to chime in on this thread. My main concern are the bowed walls (pics attached). As you can see, I don't think the walls are a MAJOR problem right now, but I don't want them to be any problem at all-- I want them taken care of! First I'll be installing drainage around the house to help draw the water away from the foundation. But what to do about the walls after that?? It is my understanding that simply repointing these walls with mortar will HELP but will not provide a long term solution. I'm thinking of pouring a sister wall along the inside instead.
Here are my questions:
1. Is repointing a worthy consideration?
2. Will a sister wall, properly formed with rebar, prevent the bowed walls from caving in? (remember, this is in conjunction with drainage which will be installed beforehand.)
3. If so, can I use the modern-day cement that all the local suppliers deliver?? These walls are 200 years old and made from stone and from the information I've read so far, cement will actually damage the stones unless it is mixed with lime.
Thanks in advance for any information!!!
