Radar exploration

Radar exploration

For rebar inspection in structural reinforcement and installation work of fall prevention fences! We will investigate embedded objects in concrete.

Our measurement principle is the "electromagnetic wave radar method." The electromagnetic wave radar method involves emitting electromagnetic waves from an antenna and utilizing the reflection of these waves at the boundaries of materials with different electrical properties (such as rebar) within concrete. It is a method for detecting embedded objects in concrete. *For more details, please refer to the related link page or feel free to contact us.*

Ground-penetrating radar survey (subsurface cavities and buried objects)

Ground-penetrating radar survey (subsurface cavities and buried objects)

If there is a difference in ground and dielectric constant, it can be explored! Wide-ranging measurements can be made in a short time.

Ground Penetrating Radar (GPR) is a method that utilizes the reflection, refraction, and transmission phenomena of electromagnetic waves to understand underground structures. Electromagnetic waves are emitted from a surface antenna (transmitter) into the ground, and the waves reflected at boundaries with different electromagnetic properties underground are measured by an antenna (receiver). By continuously arranging the measured reflected waves, a reflection profile is created, and by interpreting the depth and extent of the reflection surfaces from this profile, the underground structure is understood. 【Features】 ■ Subsurface information is displayed on a dedicated monitor in real-time ■ Wide-area measurements can be performed in a short time ■ Efficient exploration of shallow subsurface information ■ Non-destructive exploration allows for easy underground investigation without damaging or dirtying the surface *For more details, please refer to the PDF materials or feel free to contact us.

[Service] Earthquake Survey

[Service] Earthquake Survey

Utilizing the property of increased elastic velocity! We will indirectly estimate the ground conditions from the layer thickness.

Our company conducts "refraction seismic exploration." This survey method involves observing refracted waves that have returned after being refracted at boundaries of strata with different underground velocities, using measuring devices installed on the surface to determine the underground velocity structure. Artificial elastic waves (P-waves or S-waves) are generated near the surface, for example, by blasting. 【Features】 ■ Utilizing the property of increased elastic velocity, we indirectly estimate ground conditions from the elastic wave velocity structure and the relationship between elastic wave velocity and layer thickness. ■ In bedrock, we use the P-wave velocity, which varies due to rock quality, hardness or softness of the bedrock, degree of weathering or alteration, and the state of fractures, as a parameter to infer the quality of the ground from differences in elastic wave velocity distribution. ■ In the field of earthquake engineering, the obtained elastic wave velocities and layer thicknesses are directly used for seismic design or seismic response analysis. *For more details, please refer to the PDF materials or feel free to contact us.
