Geotechnical Laboratory Test

Professional Geotechnical Laboratory Testing Services

Our Geotechnical Laboratory provides accurate and reliable soil, rock and aggregate testing services to support safe and sustainable construction projects. Using internationally recognized standards and modern laboratory equipment, we conduct comprehensive testing to determine the engineering properties, strength and behavior of construction materials. Our laboratory provides professional geotechnical laboratory testing services including soil testing, rock testing and aggregate testing for engineering and construction projects.

Geotechnical laboratory tests are essential for site investigation, foundation design, road construction, building projects, bridges, dams and infrastructure development. Our testing services help engineers and project owners understand material properties to ensure structural stability, safety and long-term performance.

We provide specialized soil testing, rock testing, and aggregate testing for engineering, construction, infrastructure, and geotechnical studies.

Soil Laboratory Tests

Soil testing is essential to evaluate the mechanical and physical properties of soil, which influence the performance of foundations, embankments and earth structures. Our laboratory performs a wide range of standard soil mechanics tests used in geotechnical engineering and construction projects.

  • Direct Shear Test

    The Direct Shear Test is used to determine the shear strength parameters of soil, including cohesion and internal friction angle. This test helps engineers evaluate the soil’s ability to resist sliding along a failure plane.

  • Unconfined Compression Test (UCS)

    The Unconfined Compression Test measures the compressive strength of cohesive soils, especially clays. It is commonly used in geotechnical investigations to estimate soil strength without lateral confinement.

  • Triaxial Shear Test

    The Triaxial Shear Test is one of the most reliable laboratory methods for determining soil shear strength under controlled confining pressure. It provides critical parameters used for slope stability analysis, foundation design, and earthwork construction.

  • Atterberg Limits Test

    The Atterberg Limits Test determines the Liquid Limit, Plastic Limit, and Shrinkage Limit of soil. These parameters indicate soil plasticity and moisture sensitivity, which are important for soil classification and construction suitability.

  • Particle Size Distribution Test

    The Particle Size Distribution Test (Sieve and Hydrometer Analysis) determines soil gradation and classification. This test identifies the proportion of gravel, sand, silt, and clay in the soil sample.

  • Moisture Content Determination

    The Moisture Content Test determines the amount of water present in soil. Moisture content plays a key role in soil compaction, strength, and settlement behavior.

  • Specific Gravity Test

    The Specific Gravity Test determines the density of soil particles relative to water. This property is used in various soil mechanics calculations including void ratio and degree of saturation.

  • Shrink and Swell Test

    The Shrink and Swell Test measures the free swell index and swell pressure of expansive soils. This test is important for construction in areas with clayey soils prone to volume changes.

  • Proctor Compaction Test

    The Proctor Compaction Test determines the Optimum Moisture Content (OMC) and Maximum Dry Density (MDD) required for proper soil compaction. These parameters are essential for road construction, embankments, and foundation works.

  • Consolidation Test

    The Consolidation Test evaluates the compressibility and settlement characteristics of soil under loading. This test is critical for predicting long-term settlement of structures built on soft soils.

Rock Laboratory Tests

Rock testing helps determine the strength and durability of rock materials used in foundations, tunneling, slope stability, and mining engineering.

  • Point Load Strength Test

    The Point Load Strength Test determines the strength index of rock samples and is often used to estimate the Unconfined Compressive Strength (UCS) of rock.

  • Specific Gravity and Water Absorption (Rock)

    This test determines the density and porosity characteristics of rock materials, which influence durability, permeability, and engineering performance.

Aggregate Laboratory Tests

Aggregates are essential materials used in concrete, asphalt, and road construction. Laboratory testing ensures that aggregates meet required strength, durability, and quality standards.

  • Los Angeles Abrasion Test (LAA)

    The Los Angeles Abrasion Test evaluates the resistance of aggregates to abrasion, impact, and grinding. It indicates aggregate durability under traffic loads.

  • Aggregate Impact Value Test (AIV)

    The Aggregate Impact Value Test measures the resistance of aggregates to sudden impact or shock, which is critical for road construction materials.

  • Specific Gravity and Water Absorption (Aggregate)

    This test determines the density and water absorption capacity of aggregates, helping assess their suitability for concrete and asphalt mixtures.

  • Aggregate Impact Value Test (AIV)

    The Aggregate Impact Value Test measures the resistance of aggregates to sudden impact or shock, which is critical for road construction materials.

  • Unit Weight of Aggregates

    The Unit Weight Test measures the bulk density of aggregates, which is used in concrete mix design and construction material estimation.
