GPI-SMTL understands the meticulous and time-consuming nature of conducting one-dimensional consolidation tests. To address this, we have invested in 46 consolidometers, enabling us to perform simultaneous testing on 46 undisturbed specimens. As one of the few laboratories with such investment in consolidometers, we are able to complete tests with enhanced efficiency.

At the forefront of innovation, our laboratory has embraced the latest advancements in geotechnical testing with the introduction of a semi-automatic triaxial test system. This cutting-edge technology represents a significant leap forward in efficiency, accuracy, and reliability, offering numerous benefits over traditional methods.
