DMT

The Flat Plate Dilatometer (DMT) is an in situ test for the determination of various key soil parameters used for geotechnical design.

The test is rapid, accurate, simple and cost effective. The results are highly repeatable and independent from the operator.   

The blade may be advanced with any field machine, including CPT rigs and drill rigs. 

DMT measurements are performed in situ, directly on the soil in its original position and state. This eliminates the disturbance caused by drilling, sampling, transportation to the laboratory and sample preparation at the laboratory. 

At each test depth, a circular steel membrane located on one side of the blade is expanded horizontally against the soil. The pressure readings are recorded at specific moments during the membrane expansion. The blade is advanced to the next test depth, typically with 0.20 m depth interval. 

DMT result profiles are available in real time during the test execution. 

The direct measurement of soil deformation enables accurate estimations of elastic modulus. 

The KD parameter provides stress history information of the soil, a very difficult property to assess with other testing methods.
