My question is similar to this thread:http://www.houserepairtalk.com/f17/water-leak-poured-basement-wall-9437/
I will investigate the suggestions given, but my problem may have a little twist, so let me describe it.
My basement is concrete block. The water supply and meter cable enter through the wall, about 30" above the floor, not through the floor. There has been a leak there since the home was built in 1993. Previous owners had no idea what caused it.
I had the area dug out this Spring to check into whether drainage tile was installed, connected, working, etc. The general contractor who saw the water supply design didn't realize what the problem was, so some gravel was added and the ditch refilled. I wish I had gotten pictures, but it is too late now to do that.
The added drainage helped a little, but didn't cure the problem. On further investigation, here is what I think the source of the problem is:
The water supply has a loose fitting PVC tube around it (about 2") and about 30" long. Originally that tube penetrated both faces of the block. There remains staining from an obvious leak that was there. Then, at sometime in the past, the plastic tube was pushed back from the inside face of the block and the area around the water pipe was sealed with what looks like a cement or mortar. The PVC pipe just sits loose in the hole that was made in the outer surface of the block. With heavy rains, there is a little leakage right at the junction of the block and basement floor. With a flexible camera, I was was able to locate where the PVC pipe penetrates the wall and see water coming down the inside of that block below the PVC pipe. The rest of the basement is bone dry.
My simple question is/are: How can the penetration on the outside of the block be sealed? Is the PVC sleeve needed?
Sorry for the long post and I wish I had pictures, but I don't.
Best regards, John
