Explore the key applications of Crosshole Seismic Survey in geotechnical engineering.
Understanding subsurface conditions is critical for the success and safety of any geotechnical or structural engineering project. Among the various testing methods available, the Crosshole Seismic Survey stands out for its high accuracy and reliability. At Epitome Geo Technical Services, we offer advanced crosshole seismic testing solutions tailored to diverse project needs across India.
A Crosshole Seismic Survey is a geophysical testing method used to determine the seismic wave velocities—primarily compressional (P-wave) and shear (S-wave) velocities—between two or more vertical boreholes. This technique provides detailed information about the stiffness, elasticity, and layering of the subsurface materials, making it ideal for deep foundation and seismic design applications.
Unlike surface-based seismic methods, the crosshole test is conducted between boreholes at specific depths, offering superior resolution and accuracy for analyzing soil and rock behavior under dynamic loads.
At Epitome Geo, we bring together technical expertise, modern instrumentation, and extensive field experience to deliver reliable seismic survey data. Our services are trusted by leading infrastructure developers, consultants, and government bodies across India.
