Professional soil testing services throughout Northland including Kerikeri, Paihia, Dargaville, Bay of Islands, and Far North District. Residential soil testing, commercial soil analysis, construction site soil testing, soil borings, percolation testing, and geotechnical soil investigation.

Soil Testing Expertise

Gumboots Consulting Engineers provides professional soil testing services throughout Northland, including Far North District and Kaipara District. Our geotechnical engineers conduct field and laboratory soil testing to characterise ground conditions for residential, commercial, and construction projects.

We carry out residential soil testing for new home builds and extensions, commercial soil analysis for development projects, and construction site soil testing for earthwork quality assurance. Our investigations include soil borings and sampling, percolation testing for onsite wastewater systems, and detailed soil classification to inform engineering design.

From a single residential test pit in Kerikeri to a full geotechnical soil investigation programme across multiple sites in Northland, our team delivers accurate, practical results that engineers, designers, and councils can rely on.

Our Soil Testing Services

Comprehensive soil testing for residential, commercial, and construction projects across Northland

Residential Soil Testing

Geotechnical soil testing for residential properties including new builds, extensions, and sections throughout Northland. We assess soil bearing capacity, ground conditions, and suitability for your specific project.

  • Test pit excavation and logging
  • Soil bearing capacity evaluation
  • Foundation soil testing and recommendations
  • Geotechnical report for building consent

Commercial Soil Analysis

Comprehensive soil analysis for commercial and industrial developments. We characterise subsurface conditions and provide detailed geotechnical parameters to support structural and civil design.

  • Geotechnical site investigation
  • Soil borings and subsurface investigation
  • Laboratory soil testing and analysis
  • Geotechnical engineering report

Construction Site Soil Testing

Soil testing during construction to verify ground conditions meet design requirements. We provide compaction testing, subgrade assessment, and earthwork quality assurance for contractors and developers.

  • Soil compaction testing
  • Subgrade bearing capacity assessment
  • Fill material testing and classification
  • Earthwork design consultation

Soil Borings & Sampling

Subsurface investigation using hand auger borings and test pits to collect soil samples and log ground conditions. Borehole data informs foundation design, slope stability assessment, and earthwork planning.

  • Hand auger and test pit investigation
  • Disturbed and undisturbed soil sampling
  • Borehole and pit logging
  • Groundwater depth recording

Soil Percolation Testing

Onsite soil percolation and permeability testing to assess suitability for wastewater disposal systems. Our percolation testing complies with TP58 requirements for Far North District and Kaipara District council consent.

  • TP58 percolation testing
  • Falling head permeability tests
  • Onsite soil investigation for wastewater
  • Disposal field sizing and reporting

Soil Classification & Environmental Sampling

Detailed soil classification to engineering standards and environmental soil sampling to characterise site conditions. Our geotechnical reports provide the data required for building consent, resource consent, and earthwork design.

  • Soil classification services (USCS/NZS)
  • Environmental soil sampling
  • Laboratory testing coordination
  • Geotechnical investigation reports
