At the Civil Engineering Management Comprehensive Testing Institute, we conduct "cavity investigations" associated with shield tunneling construction. In recent years, the demand for cavity exploration has increased not only for handheld ground-penetrating radar but also for vehicle-mounted ground-penetrating radar, which can quickly and broadly survey road surfaces. As experts in infrastructure inspection and maintenance, our company actively engages in both investigation methods. [Examples of Investigations] ■ Pre-investigation of cavities ■ Post-investigation of cavities *For more details, please refer to the PDF materials or feel free to contact us.

The test involves installing a chamber on the concrete surface and reducing the pressure to calculate the permeability coefficient from the internal pressure changes, thereby evaluating the density of the concrete surface. The testing equipment used is "Permea-TORR." There is an increasing number of sites using surface permeability tests as a method for quality control of newly constructed structures. 【Features】 ■ Calculates the permeability coefficient from internal pressure changes ■ Evaluates the density of the concrete surface ■ Testing equipment: Permea-TORR *For more details, please refer to the PDF document or feel free to contact us.

• Structural Survey

The "Oil Tank Bottom Plate Gap Measurement Technology" is a technique that allows for the non-destructive measurement of gaps and unevenness in the foundation beneath the bottom plate from above the bottom plate of the tank. By using a gap measuring device set on the bottom plate, the gap distance can be determined, and if the thickness of the bottom plate and its level are known, the shape of the foundation ground can be inferred from the gap distance. Additionally, this technology is also utilized in construction management for foundation repair work. 【Features】 ■ Non-destructive measurement of gap distance from above the bottom plate, with the ability for repeated measurements ■ Measurement time is approximately 3 minutes per point, which is relatively short ■ Efficient measurement of multiple points ■ Measurement range for gap distance is approximately 0 to 20 cm ■ In addition to gap measurement, moisture (relative value) of the bottom plate foundation can also be measured simultaneously *For more details, please refer to the PDF document or feel free to contact us.

When constructing mass concrete, it is necessary to conduct sufficient consideration in advance regarding temperature stress and temperature cracking due to the hydration heat of cement. Our company conducts studies on temperature cracking through three-dimensional temperature stress analysis and will assist in setting parameters such as the size of the pouring section, height, position and structure of joints, and time intervals for pouring. For customers facing budget constraints, we are open to consultations to create a simplified analysis model to reduce costs as much as possible. 【Features】 ■ Analysis of various civil engineering and architectural structures ■ Support for two-dimensional and three-dimensional analysis ■ Consideration of a wide range of countermeasures *For more details, please refer to the PDF materials or feel free to contact us.

At the Civil Engineering Management Comprehensive Testing Institute, we are conducting "Tunnel Repair Works." The main types of work we handle include crack injection (low pressure and high pressure), crack filling, cross-section restoration, surface impregnation, spalling prevention, drainage line installation, and backfill injection, among others. From preliminary surveys to quality control and construction management, we provide comprehensive assistance tailored to your needs. Additionally, we can also carry out other works such as building settlement correction and soil contamination remediation. [Main Types of Work (Excerpt)] ■ Crack injection (low pressure and high pressure) ■ Crack filling ■ Cross-section restoration ■ Surface impregnation ■ Spalling prevention *For more details, please refer to the PDF document or feel free to contact us.

• Concrete construction

At the Civil Engineering Management Comprehensive Testing Institute, we conduct ground movement impact surveys known as "building surveys." We provide a one-stop service from preliminary surveys to post-surveys and compensation calculation (in cases of monetary compensation). By conducting preliminary building surveys, we can understand the damage status of neighboring buildings and facilitate early resolution of issues. 【Features】 ■ Preliminary building survey: Understanding the pre-existing condition of the building ■ Post-construction building survey: Confirming impacts after completion (investigation of affected areas) ■ One-stop service ■ Other surveys can also be conducted (vibration and noise surveys, asbestos surveys, etc.) *For more details, please refer to the PDF materials or feel free to contact us.

"ELEFOOT" estimates the bearing capacity not by using conversion formulas from dynamic tests, but rather through direct loading tests similar to plate load tests, easily determining the ground bearing capacity from the "load-settlement curve." It is suitable for confirming the bearing capacity of long retaining walls and large structures, as well as for estimating bearing capacity during preliminary investigations. Additionally, if there is a lack of bearing capacity, measures can be discussed immediately. 【Features】 ■ Easily determine ground bearing capacity from the "load-settlement curve" ■ Immediate discussion of measures if there is a lack of bearing capacity ■ Ministry of Land, Infrastructure, Transport and Tourism recommended technology (SK-070010-VG) *For more details, please refer to the PDF materials or feel free to contact us.

• Geological Survey Company

We are engaged in non-destructive testing services centered around ground-penetrating radar exploration using radio wave technology. Ground-penetrating radar is a detection device that uses the same principles as radar mounted on aircraft and ships to project radio waves into the ground or structures, allowing for the diagnosis of internal objects without excavation or destruction. We contribute to society by utilizing technologies such as 3D radar and pulse-based ground-penetrating radar for the investigation and diagnosis of various infrastructures that are at risk of aging. Our company uses a "high-speed mobile 3D radar exploration vehicle, Road Scan Vehicle," for investigation operations. *For more details, please download the PDF or feel free to contact us.*
