Based on the suggestion of the installer we soaked the area outside where the injections had been made in the basement walls and there was some remaining seepage. The installer returned and did more injections, performed an additional test and there was no more leakage into the basement. There has not been any leakage since, even after some strong rain storms that have occurred since. Thank you!
