ppag. 1037 - 1038 ………”In 1973, an Italian contractor, Romano Colla, was the first to form CCP columns using ultra-high pressures (5000 psi.) and high flow rates (100 to 250 1./min.) through two rather large injectors (1.8 to 2.4 mm diameter). The CCP technique originally proposed by Nakanishi and later modified by Colla is the CCP jet grouting method presently used in South America by Novatecna.”
