I am looking for recommended details of joints between individuals panels of concrete slurry walls. The project involves 150 ft deep, 60 ft diameter shaft. Concrete slurry wall is one of the contemplated options. However panel joint integrity and groundwater leakage into the shaft is a major concern. We are considering using CWS (Couffrage avec waterstop) jonts patented by Bachy Soletanche. However, I am not aware of any recent applications of CWS in the US. Any suggestions are welcome.
