In my basement we have a leak coming through the wall where the main water line comes in the house, it is not the pipe itself, it is from the ground outside being wet from all the rain and coming through. We tried quick cement but because of it still leaking and just ran right back down. When we got the water line through we had to put a whole in the wall with a sludge hammer in order to get the pipe in, and its is leaking in that whole right around the pipe!
You need to use "hydraulic cement". This product is meant to seal cement in even a wet environment. It sets very fast and expands as it sets, helping to seal water leaks.
Hope this has helped.
Did you try using thewater stop Hydraulic Cement?
Trick is to mix it with a minimal amount of water to where you can make a thick batch size of the golf ball. You will only have 2 -3 minutes to mix it ...once you get it shaped pack it around the pipe. You may want to find something flat that will allow you to pack it in around the pipe.
Hope this helps,
Thank you so much, I will try that!
Thanks for the help!
That is actually what they bought, but when they tried it, they were doing a thin base, instead of a thick base.
