Our company is engaged in the investigation and analysis of soil and groundwater contamination, as well as remediation work. Based on the expertise we have cultivated as a group of ground specialists (Geo-Doctors), we analyze the extent and conditions of contamination and propose purification methods according to the contaminants and remediation objectives. We are currently offering a document that briefly introduces the investigation and remediation methods for "historical surveys, soil surveys, and purification work." You can view it immediately via PDF download. [Contents] ■ What is a historical survey? ■ What is a soil survey? ■ What is purification work?
Asphalt mats that protect harbors and coastlines from disasters.
The asphalt mat is formed by embedding reinforcing core materials, lifting wire ropes, and lifting fittings within asphalt aggregate. It is widely used in hydraulic structures from rivers and coastlines to oceans, and can also be used for prevention of permeability, slope protection, water cutoff works, and anchoring measures. 【Main Uses】 ■ For Increasing Friction - By installing it between caissons, block walls, etc., and the riprap, it is possible to use a friction coefficient of 0.8, allowing for a reduction in cross-sectional width. ■ For Erosion Prevention - It can bend into the slopes of erosion holes that occur on the front and back surfaces of riprap mounds and wave-dissipating blocks in ports and coastal structures, stopping the progression of erosion. ■ For Preventing Suction - It can be laid on the bottom surfaces of riprap mounds and wave-dissipating blocks to prevent the suction of bottom materials (sand). - It can be laid on the back side of riprap mounds for reclaimed shorelines to prevent the loss of backfill materials due to suction. *For more details, please download the PDF or contact us.
Tunnel and water conduit investigations, buried pipe surveys, subsurface cavity and archaeological investigations! Also capable of measuring surface reflectance.
Our company conducts "cavity surveys." Borehole measurements allow for the rapid measurement of the shape and dimensions of underground cavities that are difficult for people to access. Accurate position and directional data of point clouds can be obtained. The radar exploration system employs RTS technology and is an all-weather system compliant with dust and waterproof standards (IP65). 【Borehole Measurement Features】 ■ A compact 3D laser scanning system that withstands harsh usage ■ Equipped with a 2-axis inclinometer and magnetic compass for accurate measurement of position and direction ■ Supports measurement of surface reflectivity ■ Outer diameter of only 56mm ■ The head unit, which houses two motors, rotates horizontally and vertically to scan the entire 360° of the cavity up to a distance of 150m ■ Accurate position and directional data of point clouds can be obtained *For more details, please refer to the PDF document or feel free to contact us.
Get peace of mind by conducting a dynamic seismic assessment before and after new construction or renovation!
Our company conducts the Waseda-style dynamic seismic performance diagnosis, which evaluates the seismic resistance of buildings by applying vibrations and analyzing their vibration characteristics. By observing the continuous micro-vibrations of the ground and the building, we measure the building's natural period, resonance coefficient, and vibration amplification factor, and calculate and analyze the seismic performance evaluation index. 【Features】 ■ Developed a method for dynamically evaluating seismic resistance (Patent No. 3857680) ■ Measurement method is simple ■ No special construction is required for the installation of vibration meters *For more details, please download the PDF or contact us.
Investigation of voids and looseness, diagnosis of structural deterioration, and investigation of underground buried pipes.
Our company conducts surveys using ground-penetrating radar. Ground-penetrating radar is a exploration method that utilizes the property of electromagnetic waves to reflect when they encounter materials with different electrical characteristics while propagating through the air or underground. By emitting electromagnetic waves from the surface or within a borehole into the ground (or within a structure) and analyzing the reflections from the target objects, we can determine the locations of underground cavities, water accumulations, buried pipes such as water and gas lines, rebar within building walls, and geological boundaries. [Examples of Use] ■ Investigation of cavities and looseness ■ Diagnosis of structural deterioration ■ Survey of underground buried pipes *For more details, please download the PDF or feel free to contact us.

Analysis using tomographic methods!
Our company proposes a method called "refraction tomography," which applies tomographic techniques such as CT scans in medical fields to conventional elastic wave exploration. Through special iterative processing, we determine the two-dimensional velocity distribution of the ground. Additionally, since the calculation accuracy is proportional to the amount of data, it is necessary to take measurement points densely. 【Application Fields】 ■ Site investigation: Classification of rocks and soil due to excavation difficulty ■ Slope disaster prevention and cut slope investigation: Estimation of the gradient of stable areas ■ Landslide investigation: Understanding the depth of moving soil masses ■ Shotcrete slope investigation: Assessing the weathering condition behind deteriorated shotcrete ■ Tunnel, dam, and natural rock mountain investigation: Rock classification based on velocity values *For more details, please download the PDF or contact us.
It is possible to uniformly and effectively mix iron powder into contaminated soil!
The "DIM Method" is a technology that directly mixes special iron powder for soil purification into the ground to clean contaminated soil affected by organic chlorinated compounds in situ. In addition to being able to directly access deep contamination sources, it can supply the required amount of iron powder in a dry form, making it less likely for ground softening to occur after construction. 【Features】 ■ Direct purification of contamination sources ■ Iron powder mixing is possible even for deep contamination ■ Since only iron powder is supplied in a dry form, ground softening is less likely to occur ■ Fundamental purification without excavation (no need for retaining wall work) *For more details, please download the PDF or contact us.
