Subsurface conditions in water bearing unconsolidated soils can often produce difficult construction situations for the installation of secant piles, slurry diaphragm walls and jet grouted impermeable zones. In certain isolated cases, ground freezing has been used to provide temporary earth support and/or groundwater control where these varying unpredicted conditions retard or even prevent construction. The concept of freezing these soils to the state of a strong, impermeable medium not only facilitates excavation, but also permits visual observation of the conditions that created the initial difficulties. This paper presents case histories where ground freezing was used as a remedial technique for slurry diaphragm walls, jet grouted base seals and secant pile excavation support. The paper evaluates the soil conditions and provides a forensic analysis of the cause of the complications that lead to the need to implement ground freezing.
