Seepage around sewer pipe at foundation
During heavy storms we are getting water seeping in around the sewer pipe where it exits the house through the foundation. How is something like this repaired?
We first experienced this problem shortly after moving into this new house (1992) when I was (over) watering the foundation plantings. We ignored it and (naturally) right after we finished the basement and had a heavy storm, it happened again. My husband dug out the ruined concrete and wrapped oakum around the pipe. He mixed new concrete and waterproofed the area.
Unfortunately, the area must have degraded again. We can see cracks through the waterproofing paint and quite a bit of water came in again. What sort of contractor should we hire and what process will they use to repair this? Any idea of cost?
