The other day we got a call from a contractor that we have done business with in the past. One of his sub-contractors put the sewer pipe through the concrete wall in the wrong place. So he was left with a 4" sewer pipe sticking through his concrete wall that had about 8' outside also. He has to eventually put the pipe in the right place, which left him with an unused pipe sticking out of the wall.
This pipe was leaking quite a bit of groundwater from all the rain we had the other day. He tried to put hydraulic cement in it to stop it to no avail. He wanted to sell the house in a day or two so he had to have the basement pipe penetration leak stopped. He called us.
Through a combination of techniques and experience. We put oakum and a polymer resin, worked that down in the pipe. This material expands and stops water from coming in. This stopped the water eventually from coming through the pipe. We also had to stop the water from coming in from around the pipe. Here we drilled small holes and injected a closed cell polymer resin material which stopped the water there. We also injected even more material in the pipe to make double sure that pipe would not leak.
After the closing he called us, he was very happy. If you are a contractor and need help with a leaking basement foundation, contact A1 Foundation Crack Repair.
