Basement stone foundation issues

House from early 1900s with a stone foundation with a concrete floor.

I believe the concrete driveway and walkway around the house was done probably 40 years ago was not pitched correctly or the joint around the house sealed very well. The concrete goes right up against the house on both sides. I am planning to repour the driveway and install french drains anyway.

After heavy rains sometimes a puddle develops in the basement on the driveway side. Also on the driveway side part of the cement floor broke open. The hole was not patched but was filled with compacted sand.

The mortar on the interior of the foundation seems a bit dry but is still intact. As far as I can see on the interior all stones are solidly held in place.

The neighbors property on one side is probably 6" higher than mine. My house has about 2.5 ft clearance to their property line. The opposite side has a driveway so it much wider. Both sides seem not to be pitched enough.

On the side with the driveway that is up against the house the interior of the stone foundation had a cement coat put over it. The are large patches of the cement coat that flaked off. Above ground on the exterior of the stone foundation the mortar deteriorated and was scrapped out and patched. As far as I can see on the interior all stones are solidly held in place.

How does one go about determining the correct course of action?

What additional information would you all need?

Any idea on costs?

Your focus has to be on the outside. You didn't mention if you have decent rain gutters & downspouts. Reseal where the driveway meets the house. Hopefully, those two things will solve the problem & you won't have to redo the driveway. Post some wide angled pics, if you can.

All the concrete around the house will be repoured anyway due to age and deterioration. Probably french drains will be installed. There are decent down spouts and gutters

I will take pics when I get back to the property.

You may not need french drains, if you pour new concrete.

Thank you for your response pulpo.

My concern is I will have to dig a 6 ft trench around the house and repoint all the stones from the outside. That is the big question. French drains I will put in just because they won't cost much.

I wouldn't attempt to re-point all that. You would be there forever. Besides that, a french drain isn't a replacement, for waterproofing. I would try to seal it with a membrane first.

You still didn't answer my question about gutters & downspouts.

For now, I would seal the space between the walk & the foundation.
