The effects of jetgrouting on pyroclastic soils are investigated by means of in situ measurements and laboratory tests, performed on both natural and cemented soils. Reported data include treatment parameters, soil properties, columns dimensions and mechanical characteristics of the cemented material, The experimental results are examined in detail, pointing out thc influence of soil properties and treatment procedures. The percentages of removed soil and retained mortar are estimated by means of back calculations, providing new information on the phenomena induced by jet-grouting. The mechanical behaviour of the cemented soil is interpreted with the criteria adopted for soft rocks.
