Interior concrete dampness in basement
Jennifer

My husband recently re-tuckpointed a portion of our 1912 built home interior stone foundation wall in the basement. Instead of water/dampness coming through the stone wall, it is now damp on the concrete floor next to the wall.  My husband is concerned that this dampness will seep into the next room which is remodeled with tile.  The concrete floor is not super thick but my husband is inclined to trench it and put in a pipe and sump to deal with the water.  Should this dampness be address or just leave it alone. Or is there another solution?   Thanks in advance for advice.

 1912 Stone foundation wall would have had a very soft mortar like a type " O " and it looks like you used a very hard & dense portland cement for the repointing this could cause the moisture that was migrating thru the soft mortar to move to the lower area. Was the floor moisture there before the repointing ?

I did not see anything in the picture that would justify a trench, maybe start out with a dehumidifier. Also check the drains and downspouts on the outside to see if they are diverting water away from the structure.
