The paper deals with the monitoring of a geogrid reinforced embankment, 5.0 m high and 600 m long, built to contain additional waste material in the municipal landfill in Modena (Northern Italy). The embankment was founded directly over the waste already placed in the landfill, consisting of\u27 compressible and dishomogeneus material, varying from solid urban waste to muddy industrial material. The geotechnical parameters assumed to characterize the fill soil and the waste material of the foundation soil are described. The settlements of the embankment and the forces and strains in the geogrids were monitored from the beginning of the construction until some months later. The instrumentation used in order to perform this control is described. The actual results are compared with those obtained from the design model and with other field tests concerning geogrid reinforced structures
