Experiences with jet-grouting technology applied to the remediation of old dump sites

The pilot study on a municipal solid waste landfill is under way. In order to chemically immobilize the waste, jet-grouting has been executed on the trial field on the landfill. Three groups of three columns cca 4 m long have been formed using lime and cement mixtures. Laboratory testing has been performed on non-treated waste samples and on the samples treated with lime admixtures. The preliminary test results are presented and some general conclusions are drawn.
