GTS offers residential soil testing, construction materials testing, and geotechincal & environmental consulting

Our Services

Residential Soil Testing

Residential soil testing consists of two different types of investigations. These are Site Classifications and Land Capability Assessments or LCAs. Councils will require a Site Classification for all new residential developments. A Land Capability Assessment will also be required for new developments on an unsewered allotment.

Site Classifications are undertaken to assess the site and provide a classification in accordance with AS2870. The site classification includes assessing the soil at the site along with other features such as topography, vegetation and even other structures. This is to ensure the correct footings are designed so that they can withstand the potential movement of the soil and restrict damage to the building in the future.

Land Capability Assessments (LCAs) are conducted on unsewered sites. LCAs are conducted to assess the site and soils capability of handling the wastewater generated by the occupants of the site. The assessments can be tailored for and give recommendations on both septic and secondary wastewater treatment systems.

Environmental Consulting Services

Our Environmental Consultants are able to conduct Environmental Site Assessments (ESAs) for residential and industrial subdivisions and new developments, along with contaminated site investigations and soil validation. GTS has extensive local experience, particularly with Bendigo’s mining history and its potential contamination issues. Our environmental consulting services include the following:

  • Environmental Site Assessment (ESA) for subdivisions and new developments
  • Contaminated Site Investigations
  • Soil validation testing for disposal at landfill
  • Soil validation testing of the excavation pits on removal of underground storage (fuel) tanks (UST)
  • Groundwater monitoring
  • Salinity assessments
  • Land Capability Assessment (LCA) for septic and wastewater treatment systems

Drilling Services

GTS operates both four wheel drive and trailer mounted drilling rigs. We also have the services of a licensed driller experienced in geotechnical and environmental investigative drilling. As such, we can offer the following drilling services:

  • Solid & hollow flight auger drilling to 10 metres
  • Washboring & rock coring (NMLC) to 20 metres
  • Standard Penetration Tests (SPT)
  • Undisturbed thin wall tube samples
  • Installation of groundwater monitoring wells (to depth of 20m). Wells are constructed using environmental PVC tubing, sand, bentonite sealing and if required lockable covers.
  • Environmental drilling & sampling
