Abstract: Nowadays new construction on weak soils has become inevitable owing to the growing worldwide scarcity of land. The weak soil deposits are commonly characterized by low strength and high compressibility. Soil improvement techniques require evolution in order to ensure effective and efficient improvement, and at the same time possess sustainable and environment friendly characteristics. The main objective of this study is to provide an overview of the factors affecting the calcite precipitation in soil. Several factors were identified including temperature, reagents concentration, pH, and injection method. These factors were found to be essential for promoting successful precipitation . Furthermore, a preliminary laboratory test was carried out to investigate the potential application of the technique in improving the shear strength and impermeability of a residual soil specimen. The results showed that both shear strength and impermeability of residual soil improved significantly upon CaCO3 precipitation through soil specimen . The improvement increased with increasing soil density.
