ABSTRACT
The design of jet grouted slabs to control basal stability or wall deflection requires careful analysis of the possible failure mechanisms for the slab. However, for the successful application of this technique, there needs to be equally careful consideration of how the slab is constructed and how the quality is checked. These construction issues need to be considered at the design stage, as the basis of the design needs to be reflected in the construction and Quality Control. This is illustrated by reference to two uses of jet grouted slabs, at Race Course Road, and Clarke Quay Station. The interrelation between the design and some of the construction aspects is demonstrated. The results of the Quality Control testing are summarised.
