This paper points out a number of basic causes for deficiency, which may be attributed almost exclusively to the fact that some contractors, tempted by what at first sight seems a relatively simple construction method, take on the construction of diaphragm walls without having a sound technical knowledge. It describes how careful interaction between management and construction team can ensure the technically perfect construction of diaphragm walls, even under the most difficult subsoil conditions. In the final section (5) some ideas and findings regarding soil mechanics processes during excavation work are explained.
