Subsurface exploration, soil sampling, and environmental monitoring.
Geotechnical & Environmental Drilling Services
Our Focus
Hunter Geotechnical Services provides comprehensive geotechnical and environmental drilling services, supporting soil exploration, site investigations, and groundwater monitoring.
At Hunter Geotechnical Services, we provide expert geotechnical and environmental drilling services for subsurface exploration, soil sampling, and site investigations. Our drilling capabilities support various key market segments, including construction, mining, infrastructure, and environmental remediation. By understanding the physical properties of soil and rock, we enable the safe and effective design of pavements, foundations, and other structures.
Our team of qualified drillers holds Certificate III in Drilling Operations (RII31835), ensuring compliance with industry standards. We are NATA Accredited for both disturbed and undisturbed soil sampling, providing high-quality data and insights to support your projects.
Key Services
Subsurface Exploration & Soil Sampling
We offer comprehensive subsurface exploration services, including soil sampling, which allows us to gather valuable information about ground conditions. Our lab can perform a wide array of tests on the retrieved samples to determine the soil’s suitability for construction and environmental safety.
Geotechnical Drilling & Investigations
Our drilling services are integral to geotechnical investigations, helping assess the structural integrity and composition of the ground. This data is crucial for the design and construction of buildings, roads, and other infrastructure projects.
Environmental Drilling & Investigations
We perform environmental drilling to assess and monitor potential contamination in soils and groundwater. Our services support environmental site assessments, remediation plans, and ongoing monitoring for compliance with environmental standards.
Monitoring Wells Installation & Analysis
We provide installation and monitoring of groundwater wells to gather long-term data on subsurface water quality, flow, and contamination levels. This service is essential for both environmental and geotechnical assessments.
Our Services
Drilling Capabilities
Our drilling fleet is equipped with the following capabilities:
- Solid Flight Augers: Ranging from 90mm to 350mm for various drilling depths and applications.
- Undisturbed Tube Sampling: Allows us to collect intact soil samples for detailed laboratory analysis.
- Bulk Sampling: Critical for pavement investigations to understand the composition and strength of soil layers.
- Concrete Coring: Used to sample and test existing concrete structures for strength and integrity.
- Environmental Drilling: Supports the assessment of potential contamination in soil and groundwater.
All operators have a Certificate III in Drilling Operations (RII31835)
Associated Tests
Our drilling services are complemented by a variety of laboratory tests to ensure thorough analysis and accurate results:
- Atterberg Limits & Shrink Swell Testing: Assess soil plasticity and its potential for expansion or contraction with moisture changes.
- Dynamic Cone Penetrometer (DCP) and CBR Testing: Evaluate the strength of soil for use in pavement design and construction.
- Acid Sulfate Soil Testing: Essential for areas where acid sulfate soils may pose environmental risks.
- Permeability Testing: Determines the rate at which water moves through soil, vital for groundwater management and infiltration assessments.
- Concrete Compressive Strength Testing: Measures the strength of concrete samples from drilled cores.
Frequently Asked Questions
1. What is the importance of geotechnical drilling in construction?
Geotechnical drilling provides critical data about subsurface conditions, helping engineers design foundations, pavements, and structures that are safe and sustainable. It also helps identify potential hazards such as unstable soil or groundwater issues.
2. How is environmental drilling different from geotechnical drilling?
Environmental drilling focuses on assessing soil and groundwater contamination. It helps identify pollutants, monitor environmental health, and develop remediation strategies, while geotechnical drilling primarily focuses on soil stability and structural design.
3. What are monitoring wells used for?
Monitoring wells are installed to track groundwater conditions over time, helping assess water quality, detect contamination, and guide environmental remediation efforts.
