Abstract:
A soil stabilization method of forming an admixture of at least one hydrogel precursor and urease enzyme, and contacting at least a portion of the admixture with soil, and forming a hydrogel network in-situ within at least a portion of the soil, wherein at least a portion of the hydrogel network includes in-situ precipitated calcium carbonate. In some embodiments, at least a portion of the hydrogel network is formed in-situ by polymerizing the at least one hydrogel precursor in the presence of the urease enzyme.
