We are delighted to welcome Studio Prof. Marchetti to our small portfolio of innovative organisations we are a distribution partner for.
Our clients have been encouraging us to support the unique Dilatometer Marchetti Test (DMT) equipment in the region and now our collaboration has come to life. The combined strength of Studio Prof. Marchetti’s expertise and innovation and Insitutek’s local support credentials and market development capability will make the DMT, SDMT and Medusa DMT proposition even more appealing. Learn more about the obtainable geotechnical parameters and their applications.
Measuring the lateral stress / pressure when testing in the soil is a real challenge. This is where the Dilatometer Marchetti Test (DMT) comes into its own.
The Marchetti Flat Dilatometer Test (DMT) consists of advancing a flat blade located at the end of a series of rods into the ground typically with a cone penetrometer rig (CPT) or with a drill rig. Once at the test depth, a circular steel membrane located on one side of the blade is expanded horizontally into the soil. The pressure is recorded at specific time intervals during the membrane expansion. The blade is then advanced to the next test depth, typically with a 0.2 m depth interval, and the process is repeated.
Alternatively, a DMT dissipation test can be carried out by halting the blade’s penetration at a desired depth and tracking how the lateral soil pressure decreases over time as excess pore water pressure dissipates.
DMT measurements are performed in situ, directly on the soil in its original position and state. This eliminates the disturbance caused by drilling, sampling and transport to the laboratory.
The profiles of the results are available real time during test execution.
Here is the range of DMT equipment for site characterisation on land or over water.
