Geo-Technical Testing
Building confidence from the ground down.
We work closely with engineers to assess ground conditions — providing fast, reliable data to guide foundation design and site development.
We team up with qualified engineers to carry out reliable, on-site geotechnical testing that helps inform smart foundation and design decisions. From scala penetrometers and shear vanes to augers and other hand tools, we’ve got all the gear (and the know-how) to get the job done right. As an IANZ accredited lab, you can count on accurate, trustworthy results—delivered quickly, wherever you need us.
Services
We provide a full range of geotechnical testing services to assess subsurface conditions, soil strength, and site suitability. Our experienced team conducts thorough site investigations, auger drilling, and sampling, delivering accurate, IANZ-accredited data. This data is then provided to qualified engineers, who use it to prepare detailed geotechnical reports and foundation design recommendations.

Geo-technical Soil Logging
Soil logging is the process of visually describing and recording the characteristics of soil layers encountered during site investigation. It includes details like colour, texture, moisture, and composition, providing important data about the subsurface conditions. This helps inform design decisions and supports geotechnical assessments.
Hand Auger
A hand auger is a manual drilling tool used to extract soil samples from proposed building locations. It allows technicians to observe soil layers directly in the field and collect samples for further analysis. Hand augering is useful for site classification and preliminary geotechnical investigation.
Scala Penetrometers
The Scala Penetrometer is a dynamic field test tool used to measure soil strength and compaction. It works by driving a rod into the ground using a standard weight and recording how far it penetrates with each blow. This test helps assess bearing capacity and ground stability for light structures or roads.
Shear Strength Tests
A Shear Vane is a simple, insitu testing device used to measure the shear strength of cohesive soils. It is inserted into the ground and rotated to determine how much resistance the soil provides. This test is commonly used to assess soil stability and design safe foundations.
Soakage Test (E1/VM1)
Soakage tests are field procedures used to determine how quickly water infiltrates into the soil. They are essential for designing onsite stormwater or wastewater disposal systems, ensuring compliance with building code standards such as E1/VM1. The results help determine if the ground can safely absorb water over time.
Testpit
Test pits are shallow excavations dug to visually inspect and assess subsurface soil layers. They provide a clear view of soil structure and allow for sample collection from undisturbed layers. Test pits are often used in early-stage site investigations to confirm soil types and groundwater conditions.
Our geotechnical services are built on strong collaboration. We gather reliable field data and work closely with qualified engineers to help shape informed design decisions from the ground up.
