Geotechnical Drilling

 Obtaining high-quality, representative information is critical to understanding the potential interaction between built structures and the ground. Speight Drilling provide accurate and efficient drilling and testing solutions, enabling you to determine soil and rock characteristics for your next project. Providing you with the best products and services, so you can obtain the results required. Over the last decade we have completed numerous successful contracts which have given us vital insight and knowledge of the unique NZ geology.

Geotechnical drilling can employ a wide range of equipment types under a variety of conditions. Speight Drilling work through each project individually - using our  knowledge and experience to help our clients achieve their objectives.

 

Some examples of geotechnical services include: 

  • Core Drilling (Sonic and Rotary): Taking 'disturbed' core samples of the ground.
  • Standard Penetration Testing (SPT).
  • Push Tubes (thin-walled samples): Taking 'undisturbed samples' of fine grained materials.
  • Cone Penetration Testing (CPT); Including CPTu and sCPT.
  • Downhole Testing: Including downhole geophysics and pressuremeter testing.
  • Instrumentation: Installation of instruments downhole including standpipe piezometers, vibrating wire piezometers, inclinometers and extensometers as well as telemetry systems.
  • Test-Pitting Services: We have a range of excavators available to dig test-pits up to 5m deep for geological logging and bulk sampling.
