Seismic Mapping
Seismic Mapping obtains the position of underground structures including Concrete Block, Box Culvert, Pipeline, etc.
Seismic Refraction
In engineering seismic exploration, seismic refraction wave method is a simple and economical exploration method that determines the subsurface velocity structure.
Microtremor Survey (Passive MASW)
Multichannel Analysis of Surface Waves (MASW) method is applied to measure the shear wave velocity in shallow layers underground. Microtremor is Passive MASW method, which possesses strong anti-interference ability and flexibility.
Active MASW
Active MASW is one conventional MASW Method, which can measure the shear wave velocity in shallow layers underground.
Cross-hole Seismic
Cross-hole Seismic is a well seismic technology that involves placing a seismic source inside one well, exciting seismic waves, receiving them with detectors in another well, and using the recorded seismic data for a comprehensive set of processing to obtain a geological profile between wells.
Parallel Seismic Test
The parallel seismic wave method is suitable for concealed pile foundation testing, without damaging the bearing platform and pile body. It obtains the position of the pile bottom and the integrity of the pile body through non-destructive testing technology.
