To round out our geotechnical engineering and other related services, GTS maintains our own AMRL-certified soils and concrete testing laboratory with a full range of testing capabilities located in our Harrisburg, PA, headquarters. GTS also conducts field tests and inspections.

Soils tests can be performed for:
 Soil-lime and soil-cement strength 
 Soil index properties

   -          Soil Classification (per ASTM D2487)
   -          Moisture content (per ASTM D2216, AASHTO T265)
-          Grain size analysis with hydrometer (per ASTM D422, AASHTO T88)
-          Atterberg (liquid & plastic) limits (per ASTM D4318, AASHTO T89/90)
-          Specific gravity (per AASHTO T100)
-          Natural density of undisturbed (shelby tube) sample
 Soil compaction and moisture density (standard or modified) (per ASTM D698/1557, AASHTO T99/180)
 California bearing ratio (per ASTM D1883, AASHTO T193)

 Direct shear strength (per ASTM D3080, AASHTO T236)
 Soil Unconfined Compressive Strength (per ASTM D2166, AASHTO T208)
 Consolidation (per ASTM D2435, AASHTO T216)

Soil Chemical tests include:
 Soil and water corrosivity such as minimum resistivity, pH, sulfate content and chloride content

Rock tests include:
 Rock Unconfined Compressive Strength (per ASTM D7012, Method C)
 Unit weight (moist/dry/saturated)
 Moisture content (per ASTM D2216, AASHTO T265)

Concrete tests include:
Concrete cylinder curing and testing
Concrete cylinder compression tests (per ASTM C40) 
 Grout cube compression tests (per ASTM C109)

Out in the field, GTS testing staff install inclinometers and piezometers, conduct core boring inspections, perform geophysical testing and evaluations, conduct field permeability tests, perform subsurface observations via borehole camera, inspect subsurface grouting, and perform sinkhole and subsidence remediation.

Additional field tests and inspections services include concrete inspection and strength testing, including concrete slump testing, air entrainment testing, foundation inspection, caisson inspection, and subgrade and compaction testing. Our field testing expertise also includes vibration analysis.

GTS' testing and inspection services have contributed to projects for state agencies, federal agencies, industries, consulting firms, and environmental organizations.
