environmentaL Investigation drilling

Speight Drilling are committed to ensuring all of our operations are completed in an environmentally responsible and respectful manner. We are a strong and trusted provider of environmental drilling, drilling in any location or ground condition from difficult to access sites and steep hills to overwater projects. Our rigs are purpose built to help minimise environmental impact.

Environmental drilling is used to investigate, assess and monitor the quality of groundwater and soils and determine the source or extent of pollution problems. Speight drilling can achieve this through many different types of drilling applications such as Auger, Mud Rotary, Air Rotary, and Sonic Drilling..Obtaining accurate data is essential to evaluating the health of our environment and for developing effective solutions to mitigate potential adverse effects of development. 

Speight Drilling have extensive experience across the South Island working for consultants, councils and landfill operators completing environmental investigations.

 

Some examples of environmental services include:

 

  • Core Drilling (Sonic and Rotary Wireline): Taking 'disturbed' core samples of the ground.
  • Push Tubes (thin-walled samples): Taking 'undisturbed samples' of fine grained materials.
  • Instrumentation: Installation of standpipe piezometers for groundwater sampling.

  • Landfill Gas Wells: We specialise in constructing gas wells for landfills all over the South Island. Our latest project for the Victoria Flats Landfill involved retrofitting a large scale Gas Collection and Destruction System.

Specialising in landfill gas well construction

 

We specialise in constructing gas wells for landfills all over the South Island. Our latest project for the Victoria Flats Landfill involved retrofitting a large scale Gas Collection and Destruction System. Numerous wells with large diameters were drilled into waste ground areas containing unpredictable and hazardous fill such as asbestos, sewerage, warped steel etc

A comprehensive Health & Safety plan was put in place prior to drill start  and covered all potentially foreseeable hazards with strategies to reduce risks effectively. A purpose built continuous auger rig was engineered to carry out the project successfully (below right picture). Clients were kept informed throughout the drilling process and pleased with the resulting landfill remediation.
