Field-Scale EICP Biocemented Columns for Ground Improvement

AbstractField-scale biocemented soil columns were installed in dry, poorly graded sand using enzyme-induced carbonate precipitation (EICP) and tube-à-manchette (TAM) permeation grouting. Column diameters ranged between 0.3 and 1.0 m, and column heights ranged from 1.0 to 2.4 m. Urease enzyme was obt...
