MASW: An Overview of Methods and Applications using Multi-channel Analysis of Surface Waves
What is Multi-channel Analysis of Surface Waves (MASW) Multichannel Analysis of Surface Waves (MASW) is a geophysical technique used for subsurface exploration. It focuses on measuring surface waves (specifically Rayleigh waves) that travel along the Earth’s surface to determine the shear wave velocity profile of the subsurface. MASW is most often undertaken using a vehicle […]
Seismic Refraction Surveys: An Overview of Methods and Applications
What is Seismic Refraction Seismic refraction is a geophysical method used to investigate the subsurface properties of the Earth by analysing how seismic waves travel through it. It relies on the principle that seismic waves change speed when they pass through different layers of material with varying densities and elastic properties. In this method, seismic […]
What is Ground Penetrating Radar (GPR)? How It Works and Common Applications
Using GPR equipment, professionals can conduct ground probing radar surveys to detect buried utilities, assess soil conditions, and locate potential hazards. This non-invasive method ensures that project sites remain undisturbed while providing detailed information on subsurface anomalies. Through GPR scanning, stakeholders can identify underground utilities, voids, and other critical features that traditional methods might miss, […]

Electrical Resistivity Tomography (ERT): Understanding Its Use in Geophysical Surveys
What is Electrical Resistivity Tomography (ERT)? Electrical Resistivity Tomography (ERT), also known as electrical resistivity imaging (ERI), is a geophysical method used to determine the electrical resistivity distribution of the subsurface. By measuring resistivity variations, it is possible to generate a detailed resistivity profile of the underground environment. This technique is widely used in geotechnical […]

Compaction Testing: Methods, Procedures, and Importance in Construction
The safety and durability of any construction project hinge on the strength and stability of its foundation. Compaction testing is a vital process that ensures the soil beneath structures and road pavements is sufficiently dense and capable of supporting heavy loads. By compacting soil to achieve the maximum dry density (MDD) under optimum moisture content […]
