The drilling rig XY-1 (China) with 20 HP capacity is used to make boreholes up to ~100 m depth in soil or rock. The hole is drilled by rotary method combined with a circulating fluid to lift the drilling cuttings upward.

Various in-situ tests can be performed inside the borehole such as Standard Penetration Test (SPT), Field Vane Shear Test (FVST), Pressuremeter (PMT) and others. The drilled borehole is also used to install geotechnical instrumentation for subsequent monitoring.

Standard Penetration Test (SPT) equipment is used to determine the consistency of soil and to obtain disturbed samples for visual identification and laboratory testing (if required). The test provides the N-value (blow count), which is widely used in geotechnical design and soil characterization.

The SPT tool set typically includes:

• A 63.5 kg free-fall hammer with guide rod
• Anvil assembly
• Split-barrel sampler with 50 mm outer diameter and a driving shoe with constant inside diameter of ~35 mm

The Osterberg piston sampler is used to obtain high-quality undisturbed samples in very soft to soft clays. Its piston mechanism minimizes sample disturbance and prevents loss of material during insertion and retrieval, producing specimens suitable for advanced laboratory testing.

• Piston action maintains negative pressure to reduce sample disturbance
• Thin-walled cutting shoe with sharpened edge for smooth penetration
• Ideal for soft cohesive soils, including below the groundwater table

Typical applications include sampling for consolidation (oedometer), triaxial, index properties (e.g., Atterberg limits), and other geotechnical characterization tests.

The thin-walled (Shelby) tube sampler is used to obtain undisturbed (UD) soil samples, particularly in cohesive soils such as clays and silts. The tube is smoothly pushed into the ground without rotation to minimize disturbance, preserving in-situ structure and water content.

• Produces high-quality UD samples suitable for advanced laboratory testing
• Thin-walled cutting edge for clean penetration and reduced sample disturbance
• Commonly used for consolidation, triaxial, direct shear, and index tests
• Samples can be sealed in the field (e.g., caps/paraffin) to maintain moisture

Shelby tubes support reliable characterization of compressibility, strength, and deformation parameters for geotechnical design and analysis.

The AIMIL Field Vane Shear Tester is used to determine the undrained shear strength of soft to medium clays in situ. It can be operated inside a casing or directly in an open borehole and is suitable for rapid strength profiling with minimal soil disturbance.

Kit components (typical):

• Torque gauge housing (Aimil, India)
• Interchangeable vane set: small, medium, large (area ratios approx. 9.00%, 9.12%, 9.25%)
• Load-cell sensor with data acquisition system and laptop
• Vane rods (≈1 m length each), Ø ~19 mm outer diameter

Typical workflow: Advance the vane to target depth, push downward about three vane diameters below the borehole bottom, then rotate at a constant rate and record peak torque to compute undrained shear strength at that depth.

The Envi AB electric cone penetrometer (CPT) is a versatile in-situ testing system that delivers fast, reliable soil stratigraphy and strength profiling. Measurement data are recorded by the memo-cone and transferred to a surface data logger for immediate quality control and interpretation. An integrated inclinometer continuously monitors probe inclination during penetration.

Key parameters include cone resistance (q_c) and sleeve friction (f_s) for soil behavior type identification and geotechnical design. The system also supports pore water pressure dissipation tests, providing critical input for evaluating consolidation characteristics (e.g., horizontal coefficient of consolidation).

The PDA uses reusable sensors—typically two accelerometers and two strain gauges mounted near the pile head—to record force and velocity during hammer impact. The blow generates a compressive stress wave that travels down the pile and reflects from shaft friction and toe resistance back to the top. Interpreting the measured signals provides the necessary information to estimate soil resistance and its distribution along the pile.

What the PDA helps determine

• Activated/bearing capacity during driving
• Hammer performance and energy transfer
• Maximum driving stresses (compression/tension)
• Pile or shaft integrity indicators

PDA testing is applicable to all pile types, including precast concrete, cast-in-place, steel, timber and composite piles, supporting both production control and forensic assessment.

Portcoast utilizes a range of geotechnical and structural monitoring instruments to measure ground and structure responses during construction and operation. These systems help ensure stability, performance, and safety of slopes, embankments, foundations, and retaining structures.

Key monitoring instruments include:

• Inclinometer system — manufactured by Geokon (USA), used for monitoring lateral movement of slopes and embankments during construction or protection works.
• Piezometers — both vibrating-wire and standpipe types, used to measure groundwater levels and pore water pressures within embankments and fills.
• Electrical water level tape — for groundwater level monitoring in observation wells.
• Magnetic extensometer — measures settlement of soft ground due to loading during soil improvement or construction stages. Includes spider magnets, plate magnets, datum magnets, telescoping couplings, and a cable reel with audible signal.
• Earth pressure cells — measure total pressure in earth fills and embankments for deformation and stress analysis.

The Menard pressuremeter provides the in-situ stress–strain response of soil. From the test curve, engineers obtain the pressuremeter modulus (E_p) and limit pressure (P_L) for geotechnical analysis and foundation design.

How the test works

• The system consists of a readout unit (at the ground surface) and a downhole probe with three cells: one measuring cell and two guard cells.
• At test depth, the guard cells are inflated to brace and centralize the probe in the borehole.
• The measuring cell is then pressurized with water, expanding a flexible rubber bladder against the borehole wall.
• As pressure increases, borehole deformation is induced. The pressure is held for ~60 s and the volume change required to maintain constant pressure is recorded.
• Each loading step generates a pressure–volume (load–deformation) curve, from which E_p and P_L are derived.

Hydrometer and sieve analysis are used to determine the grain size distribution of soils, which is one of the most fundamental parameters in soil classification and behavior analysis.

The test is performed in two stages:
– Sieve analysis for coarse-grained soils (> 0.075 mm)
– Hydrometer analysis for fine-grained soils (< 0.075 mm)

The results are plotted as a grain size distribution curve, representing the percentage by weight of material finer than each particle size versus the logarithm of the particle diameter. This curve provides important parameters such as: D₁₀, D₅₀, D₆₀, D₉₀ (effective particle diameters) and the coefficient of uniformity (C_u).

Testing and reporting are carried out in full compliance with ASTM D422 – Standard Test Method for Particle-Size Analysis of Soils.

The vacuum pycnometer is used to determine the specific gravity of soil solids, which is a key parameter in geotechnical engineering for computing unit weight relationships and evaluating soil composition.

The test is performed according to ASTM D854 – Standard Test Method for Specific Gravity of Soil Solids by Water Pycnometer. The vacuum is applied to remove entrapped air from the soil–water mixture, ensuring accurate measurement of displaced water volume.

This equipment is commonly used in laboratories for fine-grained soils such as clays and silts, providing precise results for density-based analyses.

The Atterberg limits test equipment is used to determine the Liquid Limit (LL) and Plastic Limit (PL) of cohesive soils — two essential indices in soil classification and behavior analysis.

The Casagrande cup apparatus is used for the liquid limit test, while the plastic limit test is performed by manually rolling soil threads until they crumble at a defined diameter. The results are used to classify soils according to consistency, compressibility, and plasticity characteristics.

Equipment is manufactured by HUMBOLDT – USA and all procedures conform to ASTM D4318 and BS 1377 standards.

The one-dimensional consolidometer (manufactured by Humboldt – USA) is used to determine the compressibility characteristics of cohesive soils under controlled loading conditions. It can achieve a maximum pressure of 64 kG/cm², suitable for both standard and high-pressure consolidation tests.

The system integrates a displacement transducer MLT connected to a datalogger by M-System (Japan). During testing, deformation data are continuously monitored, recorded, and analyzed using M-System software. Safety alerts are automatically triggered when strain values exceed the permissible limits.

The equipment provides precise settlement–pressure data used to determine soil parameters such as coefficient of consolidation (C_v) and compression index (C_c), essential for predicting long-term settlement in geotechnical design.

The CRS consolidation system completes a full consolidation test within about one day, compared to several days for the conventional one-dimensional oedometer. Loading and unloading are automatically controlled by ICON software, reducing operator error and improving repeatability.

The system’s fully automated data acquisition uses high-resolution transducers (up to 22-bit) for precise deformation and pore pressure measurements, enabling reliable parameter derivation and real-time QA/QC.

Typical outputs include compression index (C_c), recompression index (C_r), reconsolidation pressure (P_max), coefficient of consolidation (C_v90), and pore water pressure response—key inputs for settlement prediction and design.
