Soil Mixing Technology (SMT) has recently emerged as a cost effective, efficient, versatile and low risk method for the implementation of a range of in-situ remediation treatments. Notwithstanding its increasing popularity due to its simple process and low cost, the real time performance and the long-term durability and the rate of contaminants released from S/S-treated waste materials remain uncertain.

This PhD research focuses on the long-term and time-related performance of in-situ application of SMT for Stabilisation/Solidification and Ground Improvement purposes. The research will address both real time and long-term samples, to help understand the binder-contaminant interactions and provide the much needed validation of the longevity of the technology. The sites involved in this research are the SMiRT Castleford site and the West Drayton site, each with a different range of organic and inorganic contaminants. The filed studies were then followed by a laboratory study to further understand soil, binder and contaminants interaction mechanism.
