Ground investigation technology - Ground penetrating radar survey

Ground investigation technology - Ground penetrating radar survey

Underground buried pipes, underground cavities, concrete diagnosis - high mobility and rapid exploration are possible.

Ground-penetrating radar (GPR) is a non-destructive exploration method that utilizes electromagnetic waves. A radar antenna placed on the surface (100 MHz to 1.6 GHz) emits electromagnetic waves towards the ground, and receives the waves that are reflected back from various underground objects (material boundaries). The received reflected waves are processed and displayed as subsurface images. Compared to trial excavation surveys, it is cost-effective and allows for continuous exploration. It has high mobility and enables rapid surveying. It can explore regardless of the material of the target objects (pipes, cavities, rebar, structures, etc.). Exploration is possible up to a depth of about 3 meters (this may vary slightly depending on soil conditions). For more details, please download the catalog or contact us.

X-ray inspection

X-ray inspection

It is possible to check the condition inside concrete with film! It works on the same principle as medical X-ray imaging.

X-ray inspection is a method that involves irradiating concrete with X-rays from an X-ray generator, capturing the internal condition on a film attached to the back side of the concrete. Using the same principle as medical X-ray imaging, the developed film allows for the examination of the internal state of the concrete, which can then be used to mark the locations of embedded objects on the concrete surface. This enables construction work, such as core drilling and anchor installation, to be carried out without damaging or cutting through embedded electrical and plumbing pipes or rebar. *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.

This service can instantly identify the position and condition of rebar, voids, cracks, and honeycombing up to a depth of 450mm. There is a diverse range of needs for exploring and diagnosing concrete in civil engineering structures such as bridges, roads, and tunnels, as well as in the fields of architecture and equipment. We cater to various user needs, from large inspection projects to small items with an area as small as a handkerchief. Please feel free to contact us. 【Features】 - No need for restricted area settings or prohibitions on entry like with X-rays - Results can be confirmed in just 4 minutes after scanning is completed - X-ray (radiography) inspections can handle wall thicknesses up to 350mm, while 3D scans can accommodate up to 500mm - Inspections can be conducted in areas where films cannot be applied, such as floor surfaces - Inspections can be performed in locations without power using a battery-operated system *For more details, please refer to the PDF materials or feel free to contact us.

Electromagnetic induction method exploration

Electromagnetic induction method exploration

Convert the change in impedance to the distance between the probe and the magnetic material! It measures the position of rebar and the cover thickness.

The electromagnetic induction method for rebar detection generates a magnetic flux by passing an alternating current through an excitation coil wound in a circular shape with copper wire inside the probe. When a magnetic material such as rebar is present within the generated magnetic flux of the excitation coil, a current flows through the magnetic material, creating a magnetic flux in the material as well. As the distance between the probe and the magnetic material changes, the magnetic flux of the material also changes, causing a current to flow in the detection coil within the probe, which results in a change in the voltage of the detection coil. This change in impedance is converted into the distance between the probe and the magnetic material, allowing for the measurement of the position and cover thickness of the rebar. 【Conditions for Accurate Measurement of Rebar Situations】 ■ One rebar nearby ■ One rebar within a wide pitch in the magnetic flux ■ One rebar within the range of the magnetic flux *For more details, please refer to the related link page or feel free to contact us.
