Soil Testing

GEOTILL’s engineers and technicians have man years of experience in testing, and investigating the physical/mechanical properties and characteristic behaviors of surface and subsurface earth materials that are relevant to a construction project. Such earth materials include soil, dimension stones, slate, soil-cement mixtures, ground water, bituminous geomembranes, slurry, rock mass, aquifers, and geotextiles.

GEOTILL’s geotechnical engineering staff has extensive experience in laboratory soil testing, field testing, sampling, and monitoring. Our expertise in laboratory testing and field work allows us to provide comprehensive geotechnical services to our clients.

Our soil testing equipment enables us to perform in-house testing of soil physical properties for most of our projects. Geotechnical testing provides supporting data and represents a key component in many of our investigations, including site characterization; seismic (earthquake) studies; evaluations of soil settlement, expansive soil behavior, soil collapse potential, ground subsidence, landslide and slope stability, and moisture intrusion; and performance assessments for dams, retaining walls, and other structures.

GEOTILL also has geotechnical field sampling, testing, and monitoring capabilities, which enable us to efficiently collect high-quality samples for laboratory testing and perform in-situ testing and data collection. Our geotechnical engineers and geologists have many years of experience in conducting field investigations, such as geologic mapping and data collection via site reconnaissance and downhole logging, slope movement monitoring by inclinometers, groundwater-level monitoring, and in-situ strength and permeability testing.


Our field capabilities include:

  • Soil boring and test-pit excavation supervision (or observation), logging, and sample collection
  • Installation and monitoring of geotechnical instrumentation (e.g., piezometers, inclinometers, crack gauges, tiltmeters)
  • In-situ moisture and density testing
  • Shear-vane test (strength)
  • Packer test (permeability)
  • Ground vibration monitoring
