Versatility In Drilling: How Our Sonic Rigs Deliver Exceptional Results

Did you know our Sonic Rigs—the Eijkelkamp CRS XL and SRS ML Duo—are equipped with dual Sonic and Rotary heads? This cutting-edge versatility allows us to switch seamlessly between drilling methods within the same borehole. By alternating between Sonic Drilling and Diamond Core Drilling, and performing Standard Penetration Tests (SPTs) within the cased borehole, we deliver comprehensive and high-value in-situ data to our clients. 

Why Sonic Rigs Stand Out 

Our Sonic Rigs are specifically designed to tackle complex site conditions that conventional drilling methods often struggle with. Here’s how they excel: 

Challenging Fill and Soil Conditions
Sonic rigs are ideal for drilling through challenging environments like landfill, landslips, or dams, where large-diameter fill, gravel, cobbles, and boulders create difficulties for standard techniques.

Alluvial Environments
Gravel-rich river systems, such as the Nepean and Hawkesbury Rivers, are no match for Sonic Drilling. Our rigs effectively penetrate these materials to provide precise geological insights.

In-Situ Testing
SPTs can be conducted within the fill or natural soil profile, capturing valuable data. For example, loose sands interspersed with gravel layers have been effectively identified on recent projects using this method.

Continuous Geological Profiling
Sonic rigs provide high-quality soil and rock recovery in most geological environments, ensuring a continuous and accurate profile of fill, soil, and rock layers.

Complex Ground Conditions
From soft clay beneath blocky fill to colluvium, basalt flows, or gravels, Sonic Drilling retrieves samples and conducts SPTs that add critical confidence to the geological model.

Precision Drilling
Sonic rigs are engineered to achieve near-vertical boreholes, delivering exceptional accuracy even in challenging conditions.

Additional Capabilities
In addition to drilling and profiling, our Sonic Rigs can also install groundwater wells within the casing, streamlining the process for hydrogeological investigations.
