The Beginning of the End of the Never Ending Waterproofing Project

Over the past 7 1/2 years I've done a lot of work repairing and waterproofing my basement. I fixed the cracks in the foundation and painted the walls with waterproofer on the inside and filled the cracks around the foundation on the outside.

Unfortunately, as you can see, I was still getting some water though the wall and floor.




So my next step is installing a sump pump relieve the hydrostatic pressure.
First that means making a hole in the floor to put the 'sump' liner into. I used an air-chisel to make a hole and dig out the dirt under the concrete. I drilled around the edge of the hole with a masonry bit and then used the air-chisel to cut a channel around the edge of the hole. I used a cold chisel and a sledge hammer to go the last couple of inches.


I used the sledge to break out the remaining concrete.

Some pretty big chunks. The concrete is about 7 inches thick.

This is as far as I got before my back told me to finally call it a day.

Tomorrow I'll dig the last foot of the hole and put in the liner, stone, and pump.
