    Cone Penetration Testing (CPT, CPTu, SCPTu)

    Cone Penetration Testing, provides real-time, high-resolution stratigraphic data for improved geotechnical decision making. Consisting of a 600 cone, friction sleeve and pore water pressure filter, measurements for tip resistance qc, sleeve friction fs and pore pressure (u2) are achieved.

    Dissipation Testing

    A useful geotechnical testing method for accurately measuring pore water pressure and identifying soil permeability characteristics.

    Flat Plate Dilatometer Testing (DMT, SDMT)

    Precise subsurface characterisation with Flat Plate Dilatometer Testing, a fast and cost-effective method for determining key geotechnical parameters and producing comprehensive geotechnical reports .

    Insitu Vane Shear Testing

    In-Situ Vane Shear Testing, a swift and efficient method to determine the shear strength of soft clays directly at your site. Our electronic Vane shear testing apparatus makes for reliable and accurate measurements.

    Rigs

    Our state-of-the-art heavy-duty rigs enable us to handle diverse projects, delivering precise results in a variety of site and ground conditions. With strong links to academic research from our university connections, we apply cutting-edge methodologies to our work.
