GRIZZLY® handset
Heavy dynamic cone penetrometer with constant energy coupled to a drilling head
It is designed for compaction control and geotechnical and geological soil investigation. Innovation designed and developed by Sol Solution. Standardised penetrometer DPSH-B (NF P 22476-2).
Mounted on tracks, the GRIZZLY® is all terrain. It can be set up quickly and the verticality of the mast can be easily adjusted by the hydraulics.
The hammering is automatic and its stop is programmed for rod addition, reaching the target depth and refusal.
The on-board data acquisition case allows for data recording, via the penetration sensor and the blow counter. The instantaneous visualisation of the sounding results can be done in cone resistance (MPa), penetration per blow or in N20.
The rod extraction system is integrated into the hammering mast.
Drilling part
Switching to drill mode is quick and easy: the drill head is installed on the mast of the penetrometer after tilting the hammering column. A place is provided for the drill head when it is not in use.
Drilling allows soil samples to be taken, geological sections to be established and pressure tests to be carried out afterwards.
The geological cross-section can be entered into the data acquisition case thanks to the automatic depth registration and the available soil library.
The GRIZZLY® handset meets the safety requirements of the Machinery Directive 2006/42/EC:
- Safety cage
- Sensitive devices
- Speed: normal/reduced mode with flashing light
- Audible alert
- Remote control for moving
Compaction control
The penetrographs obtained are compared with reference lines established according to the class of the material tested and the required compaction quality. Any anomalies are automatically calculated in accordance with standard NF P 94-063.
The reference lines and the anomaly calculation are available on the GRIZZLY® acquisition case, allowing an assessment directly on site, and also on the Websprint© online application.
Type of anomaly calculation :
- On the total height (NF P 94-063)
- Per layer of constant density
- By backfill or coating area (Fascicule 70-1)
Soil investigation
Interpretation of the penetrographs is the responsibility of the geotechnical engineer who will be able to assess the estimated bearing capacity of the soil but also to establish correlations with other geotechnical tools (SPT, CPT, CBR, etc.).
It is used in accordance with NF EN ISO 22476-2 and NF P 94-115 in soil investigation.
The Websprint online application allows you to retrieve or create geological sections and compare them with the GRIZZLY® penetrographs.

Websprint©
The Websprint© geotechnical web application, developed by Sol Solution, offers a new, more collaborative, mobile and secure way of working.
It’s an alternative to geotechnical software. It is multi-equipped, accessible from an office or worksite, and very easy to use.
DISCOVERSol Solution offers technical training in the field of geotechnics applied to civil engineering and public works. The use and interpretation of data acquired by the company’s equipment such as dynamic penetrometers can be included in our training courses. All of our trainers are from the field of earth sciences or civil engineering (geotechnician, geologist, […]
