The laboratory soil testing equipment consist of a Triaxial Testing Apparatus Model No. DTC-367 - Seiken Inc., which fulfills all the requirements of The Japanese Geotechnical Society (2000).

The triaxial equipment can solve the following types of problems:

• static problems with strain level at 10^-3 or greater (the main concern regarding the static problems is used to evaluate the degree of safety of foundations or soil structure against the failure);
• dynamic problems with soils subjected to a strain levels as small as 10^-6 (used to evaluate the soil strength in comparison with stresses induced by external loading and the settlement of ground or structures associated with the deformation of soils.
