Geotechnical Investigations

It is conducted by site characterization, laboratory testing, and professional interpretation

Geotechnical Investigation Services

Geotechnical and geophysical investigations are essential in offshore and onshore projects to assess the subsurface conditions and potential hazards.

Geotechnical investigation is a process of soil / rock sampling and testing to determine the stratification and engineering properties of the site underlyingfor designing purposes. The principal of interest will be the strength, deformation and hydraulics characteristics. Generally, these informations shall provide recommendations for foundation,settlement, groundwater issues, permeability, slope stability, retaining wall, dewatering, and any other potential problems. Investigation of the underground conditions at a site is prerequisite in almost any construction structures such as buildings, bridges, roads, dams, power plants, tunnels, ports, pipelines, and many others.

Offshore Geotechnical Investigations

Offshore geotechnical investigations involve exploring the seabed to gather information about the soil and rock beneath the ocean floor. This data is essential for the design and construction of offshore structures such as oil platforms, wind farms, and underwater pipelines.

Seabed Sampling

Extracting core samples from the seabed to analyze soil and rock properties. Collecting surface samples to assess the composition and characteristics of the seabed material.

In-Situ Testing

Measuring the resistance of the seabed to a cone-shaped probe to determine soil strength and composition. Evaluating the shear strength of seabed soils by rotating a vane into the ground and measuring the resistance.

Laboratory Testing

Determining the type and properties of soil samples collected from the seabed. Assessing the compressive and tensile strength of seabed materials.

Onshore Geotechnical Investigations

Onshore geotechnical investigations involve assessing the subsurface conditions on land to support the design and construction of various infrastructure projects. These investigations help in identifying potential challenges and designing foundations that can safely support structures.

Borehole Drilling

Creating boreholes to collect soil and rock samples from various depths. Extracting samples from boreholes for laboratory testing and analysis.

In-Situ Testing

Measuring soil resistance to a driven sampler to assess soil properties. Determining the deformability and strength of soils by inflating a probe in a borehole.

Laboratory Testing

Analyzing samples for properties such as grain size, plasticity, strength, and compressibility. Identifying the presence of harmful chemicals or contaminants in soil samples.

Benefits of Geotechnical/Geophysical Investigations

Foundation Design

Providing critical data for designing safe and effective foundations for structures.

Risk Mitigation

Identifying potential subsurface hazards such as sinkholes, landslides, or soil liquefaction.

Cost Efficiency

Optimizing design and construction methods based on accurate subsurface information,

Regulatory Compliance

Ensuring that projects meet all regulatory requirements related to subsurface conditions.
