The GRIZZLY, a self propelled dynamic probing and drilling rig used for soil investigation and compaction control to measure the in-situ strength of fine- grained and granular subgrades, base and sub base materials, and weakly cemented materials. Depths of 10-15m or more can be achieved, depending on the soil type. The GRIZZLY provides immediate repeatable results so that on-site decisions can be made straight away and adheres to EN ISO 22476-2. Attachments available include a geotechnical drilling head and auger (diameter 63 mm) for soil investigation at depth, push tube sampling and a Standard Penetration Test (SPT) core sampler.
The Variable Energy option converts the GRIZZLY® from a constant dynamic energy penetrometer (DPSH) into a Variable Energy version, providing high resolution, reliability and accurate measurements in softer soils by automatically adapting to the resistance of the soils encountered during the test.
The GRIZZLY compares favourably with the Cone Penetration Test (CPT) because the GRIZZLY can test in materials that you cannot test with a CPT (e.g. course gravels) and does not have high cost wearing parts (like CPT sensors and their calibration).
