Laboratory Testing
TerrAtlantic has significant capabilities with the laboratory testing of soil and rock. A number of highly-specialized tests for the evaluation of geotechnical properties of a wide range of materials can be conducted in our state-of-the-art geotechnical laboratory. These services include:
Shear Strength Evaluation
- Triaxial testing of sand and clay samples up to 4" in diameter (ASTM D2850)
- Triaxial testing under zero lateral strain (Ko) conditions
- Direct Shear testing of sands (ASTM D3080)
- Simple Shear testing of organics and soft clays
- Unconfined compression testing of cohesive soils (ASTM D2166)
Hydraulic Conductivity Evaluation
- Flexible wall permeameter testing of low permeability soils (ASTM D5084)
- Rigid wall permeameter tesing of low permeability soils
- Constant head permeameter testing of granular soils (ASTM D2434)
Other Laboratory Tests
- Grain size analysis including hydrometer (ASTM D422)
- Atterberg Limits (D4318)
- Standard and Modified Proctor compaction tests (ASTM D698)
- Consolidation testing (ASTM D2435)
- California Bearing Ratio (ASTM D1883)
- Point Load (Brazilian) Testing
- Data Acquisition and Processing including continuous pressure, load and displacement monitoring.
