Sample Collection and Preparation:

• Soil and rock samples are collected from boreholes, test pits, or other subsurface exploration methods.
• Representative sampling is crucial to ensure the laboratory test results accurately reflect the in-situ conditions.
• Care is taken to preserve the integrity of the samples during transport to the laboratory.
• Special precautions are employed to prevent changes in moisture content, which can affect test results.
• All lab testing is handed over to our sister company PT. Geoland Quattro Technolab (Rock Mechanics) and PT. Minearth Solution (Soil Mechanics).

Soil Engineering Properties Testing

Consolidation Testing:

• Evaluates the compressibility and settlement characteristics of soil under loads.
• Helps estimate settlement and assess the time-dependent behavior of soils.

Triaxial Shear Testing:

• Measures the shear strength and stress-strain behavior of soil samples under different confining pressures.
• Essential for slope stability analysis, foundation design, and understanding soil behavior under load.

Direct Shear Testing:

• Determines the shear strength of soils by applying a direct horizontal force.
• Commonly used for cohesionless soils and provides valuable input for slope stability studies.

Unconfined Compression Testing:

• Measures the compressive strength of cohesive soils without lateral confinement.
• Useful for characterizing the strength of soft soils.

Rock Mechanics Testing

Point Load Index Testing:

• Measures the strength of rock samples under point load conditions.
• Provides a quick assessment of rock strength for preliminary design considerations.

Uniaxial Compression Testing:

• Applies axial load to rock samples to determine compressive strength and modulus of elasticity.
• Critical for understanding the load-bearing capacity of rocks in engineering projects.

Brazilian Test:

• Evaluates tensile strength by inducing a tensile stress across the center of a disc-shaped rock sample.
• Useful for assessing rock durability and fracture behavior.

Permeability Testing:

• Constant Head and Falling Head Permeability Tests.
• Assess the ability of soils to transmit water under different hydraulic gradient conditions.
• Important for groundwater flow analysis, seepage studies, and design of drainage systems.

Slake Durability Testing:

• Evaluate the resistance of rock to weathering, especially when subjected to wetting and drying cycles.
• Evaluate the long-term stability of rocks, especially in terms of their ability to withstand the effects of moisture and environmental stressors.
