MASW stands for Multichannel Analysis of Seismic Waves, and is a way to measure the Shear Wave velocity (Vs), which is an elastic constant of Young’s modulus. This helps to determine the ground strength, or stiffness, and load-bearing capacity.
MASW is also used to map out soil strength without the need for drilling. This helps to identify rock head depth, soil stiffness, and void location.

Masw section
A very powerful and fast geophysical method.
Utilize a geophysical survey and advanced processing techniques to precisely measure the Shear wave velocity of the soils.
Active mode – to 25m
Passive Mode up 100m range . No need for sources uses natural ground noise source
