Our daughter has purchased a house built in the late 40's or early 50's (specs said 1953). There was concrete floor in the laundry room and the rest of the basement had a sub floor. There was a bathroom with shower in the basement that really was in rough shape. The intention was to pull out all the walls and subfloor and start again as it was not done in a professional manner.
After taking out the shower, it was found they had not put in a vapour barrier against the concrete wall and it crumbled away in a spot about 3 feet wide, two feet high and about 4 to 6 inches deep.
The next surprise was that only half the basement was concrete. There's dirt floor under the other half!!!
My questions are - Can you repair an old concrete wall with new materials?
Do you have to dig out the dirt prior to pouring the rest of the concrete floor.
Should they be digging up the existing concrete floor and pour the entire basement??
The house is only 670 to 700 square feet and this is a very young couple one of whom is going to university so money is tight.
