I live in a house built in 1952, I am the 3rd owner. The neighborhood is full of underground springs. When my house was constructed steps were taken by the builder to address anticipated moisture problems associated with a spring or capillary that runs underground past the corner of the house. Additional cement was put on the exterior below the brick about 6 feet down in the ground. Inside they used a technique of 2 rows of cinder block, one row of brick, repeated all the way up. I was told that they use the brick because it doesn't absorb moisture and sort of caps the water in the cinder blocks below. I did not know about this spring at the time of purchase or I would not have bought the house.
In the past 3 years we have had severe flooding inside whenever rainfall exceeds 4 inches of sustained downpour. The water pours in just like a flooded stream and is clear, no dirt, silt, or debris. Usually it is about 2-3 inches in depth just racing across the floor.
I have had one waterproofing company out, 2 more to go. The popular trend seems to be to install an internal system that equates to a French drain around the perimeter of the inside of the basement wall. Sounds good but this just does not compute for me. They only go down 10 inches and out 14" using a sump pump to evacuate the water through a 1 1/2" pipe to the outside. My instincts tell me this system will not remove the water as fast as it comes in.
I need advice/guidance on what is proper and appropriate to deal with this problem.
