I have a vertical crack in the poured concrete foundation of my house that runs from the top of the wall to the floor. The house is less than 2 years old. My builder came back and chiseled out the crack from the inside and then patched with hydraulic cement.The crack still occasionally leaks water. The builder now wants to chisel away the hydraulic cement patch and have the crack filled with some kind of epoxy filler.( Which he should have done to begin with ) Should the hydraulic cement patch be disturbed at this point? I'm worried about creating a worse problem than I have now. I would rather have the crack fixed from the outside but I'm sure he doesn't want to dig up the yard. Any suggestions?
