Laboratory Services

GRI offers a diverse suite of testing capabilities for soil, cement-treated soil, and soft rock out of our in-house, fully equipped soil-mechanics laboratories.

The laboratories are also equipped to run all standard soil classification tests, including natural moisture content, Atterberg limits, grain-size analysis, unit weight determination, moisture-density relations, and California Bearing Ratio tests. Our laboratories are managed and operated by engineering and geological staff members experienced in testing soil and rock for engineering applications and interpretation and practical application of the test data.
