Rapid, High-Quality Core Recovery
Sonic Drilling is a specialist capability offered by GEOGROUP. This low-impact, high-frequency vibratory method significantly reduces drilling time and is particularly valuable for complex and sensitive geotechnical and environmental investigations, notably in challenging unconsolidated materials and on large-scale Tailings Storage Facilities (TSFs).
The core benefit of the sonic technique is the recovery of a continuous, high-quality core—typically 3-inch and 6-inch diameter —that is virtually undisturbed, which is crucial for accurate soil characterisation, especially in soft, sensitive, or challenging layered formations.
