Ensuring safety 'with certainty.' Leave geological and ground surveys to us.

Our company conducts "geological and ground surveys" to investigate whether the site has the strength to support structures and to assess the potential of the land. We investigate the composition, distribution, and interrelationships of geological layers, as well as geological structures and other information about the underground environment through methods such as drilling. This work is essential for creating safe towns that are resilient to disasters. Please feel free to contact us if you have any inquiries. 【Main Services】 ■ Geological and soil surveys ■ Various in-situ tests ■ Landslide surveys and analysis ■ Hydrological surveys *For more details, please download the PDF or feel free to contact us.

Residential land survey service

Residential land survey service

We will comprehensively assess using various survey instruments and propose measures for ground that does not sink.

Our company offers a "Residential Land Investigation Service" to assess the strength against land load and subsidence during building construction. First, we understand the land conditions by reading topographic maps and land condition maps during the preliminary survey to grasp what the land was like before it was developed into residential land. Next, we conduct an actual survey around the client's land to check for any nearby houses that may be experiencing subsidence, examining a variety of unique items filled with our extensive know-how. Finally, we utilize advanced equipment to investigate the bearing capacity and soil resistance of the client's land using the penetration method. Additionally, for land where the surface is hard and difficult to investigate using the penetration method, we can conduct thorough investigations by inducing minor earthquakes that are undetectable, allowing us to explore the characteristics of the ground based on their effects. Please feel free to contact us if you have any requests. *For more details, please download the PDF or contact us.*

Ground investigation service "Swedish-style sounding test"

Ground investigation service "Swedish-style sounding test"

It is recommended in the "Guidelines for the Basic Design of Small-Scale Buildings" edited by the Architectural Institute of Japan.

At Geotech Co., Ltd., we offer a wide range of services including the commonly used Swedish sounding test for residential foundation surveys, as well as boring surveys suitable for large buildings and various soil tests. The "Swedish sounding test" was adopted around 1917 by the Swedish State Railways for investigating poor roadbeds and later became widely used in Scandinavian countries. It was introduced in Japan around 1954 by the Ministry of Construction for foundation surveys of embankments. In 1976, it was established as a JIS standard, and now most foundation surveys for residential houses are conducted using this test, known as JISA1221 (2002). 【Features】 ○ A rod with a screw point attached to the tip is loaded with up to 100 kg to measure penetration. ○ When penetration stops, the handle is rotated to screw it into the ground, measuring the half-turn Newton required to screw it in 1 meter. ○ During the test, sounds transmitted through the rod and penetration resistance are used to differentiate between sandy soil and clayey soil. ○ In soft strata, surveys can be conducted to a depth of about 10 meters. For more details, please contact us or download the catalog.

Ground investigation service "Standard Penetration Test"

Ground investigation service "Standard Penetration Test"

It is the most commonly conducted ground survey during the design and construction phases of construction work.

The ground investigation method commonly referred to simply as boring investigation is formally known as the boring and standard penetration test. This investigation utilizes holes drilled by boring (i.e., hollowing out) to conduct standard penetration tests that measure the hardness of the ground at intervals of one meter. Typically, this is carried out simultaneously with soil sampling. The data obtained from the standard penetration test is referred to as the N value, which can serve as a guideline for estimating ground stability. 【Features】 ○ The most commonly conducted ground investigation during design and construction in construction projects. ○ Clarifies the composition of strata by excavating the investigation site and observing the soil. ○ Measures the N value to understand the relative hardness and compactness of the soil in situ. ○ Can penetrate any deep or hard layer. For more details, please contact us or download the catalog.

Ground investigation service "Liquefaction Survey"

Ground investigation service "Liquefaction Survey"

We have prepared a four-stage method ranging from a preliminary assessment based on data to a detailed assessment involving boring investigations.

Liquefaction surveys (liquefaction assessments) are investigations that determine the potential for liquefaction during an earthquake based on ground and water level conditions. By understanding whether the site is prone to liquefaction and implementing appropriate liquefaction countermeasures, damage can be minimized. GeoTech Co., Ltd. offers four levels of methods, ranging from preliminary assessments based on documentation to detailed assessments involving boring surveys. 【Features of GeoTech】 ○ Experienced analysis staff (3 certified geological survey technicians) ○ Many employees hold qualifications as residential ground technicians and chief technicians from the NPO Housing Ground Quality Association ○ Ground consulting before and after the survey ○ Achievements in ground surveys and ground reinforcement work in the metropolitan area are compiled in the Ground Information Provision System (GEODAS), improving diagnostic accuracy through database creation and comparison with neighboring data ○ Courteous service to clients For more details, please contact us or download the catalog.

Ground investigation services

Ground investigation services

We provide various survey methods to investigate the ground.

Our company conducts ground investigations to confirm the condition of the strata that serve as the foundation for buildings, and, if necessary, to examine the physical properties of each stratum in detail. Depending on the environment in which the ground is formed, there may be locations where soft strata accumulate, as well as places where hard bedrock appears. Therefore, it is essential to obtain detailed information about the "ground" that cannot be discerned by merely looking at the surface. To investigate the ground, we offer various survey methods. Please feel free to contact us if you have any requests. 【Main Survey Methods】 ■ Boring Survey (Standard Penetration Test) ■ Sounding Test ■ Load Test ■ Investigation for Seismic Design *For more details, please do not hesitate to contact us.
