Geotechnical Investigation

Field investigations are conducted using various Boring techniques, such as Auger Boring and Rotary/Hydraulic drilling. In our lab in Bangalore, we conduct comprehensive geotechnical investigation on soil and rock samples to precisely determine their physical and mechanical properties. These properties play a pivotal role in various industries, including construction, geotechnical engineering, environmental science, and more. Our testing procedures encompass a range of critical parameters ensuring the safety and durability of structures while optimizing construction techniques.

These below tests and techniques collectively form a comprehensive approach to geotechnical investigation, ensuring the safety and integrity of construction projects.

  • Permeability Test:Determines soil's ability to transmit water.
  • Porosity on Rock:Assesses the pore space in rock samples.


Piling techniques are foundation construction methods used to transfer structural loads from a building or structure to a deeper, more stable soil or rock layer. These techniques involve the installation of piles or deep foundations below the ground surface to provide support and stability for various types of structures. Piles can be made of various materials, including concrete, steel, timber, and composite materials. Here are some common piling techniques:

  • Bored Cast In situ piles
  • Micropiles
  • Contiguous piles
  • Driven Piles


Ground improvement techniques are a set of geotechnical engineering methods used to enhance the properties of soil and rock in order to meet the requirements of a construction project. These techniques are employed to improve the load-bearing capacity, stability, settlement characteristics, and drainage properties of the ground. Ground improvement is commonly used in areas where the existing soil or rock conditions are not suitable for the intended construction. Here are descriptions of some common ground improvement techniques:

  • Shotcreting
  • Soil Nailing
  • Ground Anchors
  • Dewatering
  • Rain Water Harvesting
  • Rock Bolting
  • Grouting


Earth retention structures are engineered systems designed to stabilize and support soil or rock masses to prevent erosion, landslides, or collapses and to create stable slopes for various construction or infrastructure projects. These structures are commonly used in civil engineering and construction to manage and control soil and rock movements. There are several types of earth retention structures, each tailored to specific project requirements and soil conditions. Here are some common types and their descriptions:

  • Anchored Sheet Pile
  • Retaining walls


Liquefaction analysis is a geotechnical engineering procedure used to assess the susceptibility of soil deposits to liquefaction during seismic events. It is crucial for designing earthquake-resistant foundations and mitigating the risks associated with liquefaction.


Slope stability analysis is a geotechnical investigation process used to evaluate the stability of natural or man-made slopes, embankments, excavations, and other earth structures. The primary goal of slope stability analysis is to assess the potential for slope failure, which can lead to landslides, erosion, and damage to infrastructure or property. This analysis is crucial for ensuring the safety and stability of slopes in various engineering and environmental contexts.
