This article describes the flat dilatometer test equipment DMT and important applications in Geotechnical Engineering. The DMT test is more often used worldwide because the equipment and testing method are reliable, adaptable and robust. Compared with conventional tests, the DMT has proved to be of lower cost, short execution time and repeatability. The SDMT consists ofa DMT with seismic sensors included in order to measure shear wave velocities VS. The DMT and SDMT can be of particular usefulness in projects where soil stiffness and settlement assessment are key parameters for an appropriate design. Moreover, applications for slip surface detections in clay slopes, determination of P-y curves in laterally loaded piles, soil improvement and compaction control, soil liquefaction potential assessment and the determination of the secant Young modulus for numerical modelling, are discussed.
