A design variant that has won the customer’s support
An increasingly important issue for investors when analysing construction proposals is not only the price associated with using a given geotechnical solution, but also the time that it can save at a subsequent stage in the construction work. One of these solutions involves avoiding the need to extend the underground structure, by using the diaphragm wall process to construct a circular shaft:
- This circular diaphragm wall structure provides very secure support for deep trenches
- It works very well, even in difficult soil conditions, with high levels of groundwater. (The structure is made watertight using the Soletanche Bachy group’s patented solution – the CWS® (continuous water stop) watertight seal system.)
Thanks to the geotechnical expertise and knowledge of special foundations of our Polish subsidiary, this variant then imposed itself as the basic solution in the rest of the project.
