ARC Laboratory Services provides rock moisture content testing to AS 4133.1.1.1. This test determines the ratio of water mass to dry solid mass in an intact rock specimen, expressed as a percentage. Moisture content is a fundamental index property in rock mechanics, influencing strength, stiffness, and durability. Many rock types exhibit significant reductions in compressive and tensile strength when saturated, making moisture content a critical input to geotechnical design, particularly for slope stability, foundation assessment, and underground excavation. Results are routinely reported alongside UCS, point load, and density testing as part of a complete rock index property suite for geotechnical and mining projects across Australia.
