Abstract

One of the difficulties for the application of microbial induced carbonate precipitation (MICP) or enzyme induced carbonate precipitation (EICP) for soil treatment is to ensure uniformity in the treatment across the whole soil sample or soil profile. Methods that can be adopted to improve the uniformity of MICP or EICP treatment are reviewed and compared. Experimental data are presented to demonstrate that a newly proposed one-phase-low-pH injection method enables better uniformity to be achieved among different methods. Other factors affecting the uniformity of treatment are discussed. Measures to be adopted to enhance the uniformity of MICP or EICP treatment in sand are suggested.
