Earth Sciences

The Earth Sciences Practice Group provides a comprehensive range of geological, geotechnical, and hydrogeological services nationally and internationally for a variety of industries, including power generation, mining, quarries, railways, highways, oil and gas, agricultural and food processing, irrigation, land development, and public works.

Our geologists, hydrogeologists, and geotechnical engineers will work closely with you to plan and implement cost-effective solutions to address your specific needs and lead your project through all the required phases.

Geotechnical Engineering

Our geotechnical engineering services include foundation design for commercial and industrial facilities; seismic site classification; slope stability investigation and remediation of landslides for railways, highways, bridges, pipelines, transmission towers, and buildings; dam safety reviews for major earthen dams and tailings facilities; design of cofferdams and dewatering systems for construction in water bodies; terrain analysis and hazard mapping for land development; and geohazard risk assessments for pipelines and highways. 

Our skills include stability, seepage, and stress-strain modeling; lateral pile and settlement analysis; soil resistivity surveys; drilling, logging, installation, and monitoring of piezometers, slope inclinometers, and settlement plates; installation of real-time remote monitoring systems to collect data and trigger alarms for risk management at sensitive sites; construction control monitoring; determination of foundation soil properties for pile design; and down-hole inspection services for piles. 

We have sophisticated tools and powerful software for performing Quality Control and Quality Assurance services during pile foundation construction.


Geology is an integral component of our hydrogeological, geotechnical, and environmental work, because understanding the physical environment and its unique challenges allows us to find the best solution for your project. Our geological services include mine planning and development, quarry development, management of waste rock, geological and hydrogeological site characterization, and aggregate resource exploration.


Our hydrogeological services include development of groundwater and transport flow models; computer modeling of groundwater flow, solute transport, geochemistry, and seepage; development of groundwater supplies for commercial and private clients; design and implementation of hydrogeological field investigations, including piezometer and instrumentation installation, hydraulic testing, pump and packer testing, and river intake feasibility; as well as construction supervision services.


Our geophysical capabilities complement and support our geotechnical and environmental engineering services. Clifton has non-destructive and non-invasive tools that collect data to assist in developing solutions for challenging projects. Our in-house state-of-art SuperSting Wi-Fi Earth Resistivity (ERT) equipment with 2D and 3D graphics and 24-channel Refraction Microtremor (ReMi) equipment with shear (S) wave and P wave velocity measurement capabilities can provide value on: environmental site assessments, contaminated site work, slope stability investigations, potential geohazard mapping, dynamic foundation design parameters, delineation of bedrock/till and overburden soil contact, seismic site classifications, void and cavern assessments, and river crossing feasibility studies. With our ERT equipment Clifton can provide design parameters for electrical grounding design work and resistivity values in accordance with the Wenner 4-pin method as described in the ASTM G57 and IEEE 81 standards.
