Dissipation testing is an in-situ testing method that measures the change in pore water pressure over time. Dissipation testing is used to assess the drainage and consolidation characteristics of soil, which are important factors in many geotechnical fields.Dissipation testing is typically performed using a piezocone penetrometer (CPTu). The CPTu is a device that measures the c ...

In September, our team of Geomech Africa drillers arrived in the North West Province of South Africa to begin a three-week drilling project. The brief was to conduct geotechnical drilling and core recovery at twelve holes, each 20 meters deep, at three different sites. These sites were 25 kilometres apart, so the team divided into two teams and worked simultaneously.The team us ...

In a few years' time, these trees would h ...

Sonic is an advanced method of drilling which uses a high-frequency energy known as an oscillation that is generated inside the Sonic head. During drilling, the high-frequency oscillation is transferred down the drill string to the bit face at various Sonic frequencies (0hz to 150hz). Simultaneously rotating the drill string (Max 90rpm) evenly distributes the energy and impact ...

Barge drilling in tidal ports is a challenging task, but it is one that requires teamwork and perseverance. In this story, we will follow the crew of a barge drilling rig as they work to drill 12 holes in two different ports in Africa, 350 kilometres apart.The crew faced a number of challenges, including: Tidal ports: The tides and large swells can make it difficult to maint ...
