Boring survey (Standard Penetration Test)

Boring survey (Standard Penetration Test)

Excavating the actual ground while conducting a standard penetration test! Simultaneously collecting soil samples along with ground strength.

We would like to introduce our "Boring Survey (Standard Penetration Test)." In general civil engineering and construction work, it is said to be an effective survey method because it allows for a standard and direct confirmation of the ground. By excavating the actual ground and using the standard penetration test, it is possible to assess ground strength while simultaneously collecting soil samples. The collected soil samples can be analyzed through laboratory tests to understand the physical and mechanical properties of the soil. 【Features】 ■ Direct confirmation of the ground ■ Simultaneous collection of soil samples and assessment of ground strength ■ Ability to understand the physical and mechanical properties of the soil *For more details, please refer to the related links or feel free to contact us.

【Services for Existing Structures】Exterior Wall Inspection

【Services for Existing Structures】Exterior Wall Inspection

Investigation of tile and mortar peeling, lifting, cracking, etc.! Introducing the exterior wall inspection conducted by our company.

Even in durable reinforced concrete buildings, natural environmental factors such as daily wind, rain, light, and heat, as well as human usage conditions, can lead to aging and deterioration of the material's strength and performance over time. Therefore, our company conducts exterior wall surveys to gather basic data for repair work and to understand the current condition of the exterior walls. Using a tapping hammer, we tap the wall surface to check for any detachment based on the sound produced. In crack surveys, we measure the width and length of cracks using a crack scale. Additionally, we can investigate wall detachment using infrared thermography, which can be used in conjunction with tapping surveys. [Survey Items] - Detachment, bulging, and cracking of tiles and mortar - Deterioration of sealing and finishing materials *For more details, please refer to the related link page or feel free to contact us.

[Services for Existing Structures] Post-Fire Investigation

[Services for Existing Structures] Post-Fire Investigation

Conducting a more accurate survey! It is also possible to investigate the estimation of the tensile strength of steel materials and the measurement of bolt axial force.

In the case of fire-resistant structures such as reinforced concrete and steel structures, most instances do not develop into large-scale fires even if a fire occurs, thus avoiding destruction. Therefore, it is necessary to accurately assess the structural safety and durability of the remaining structures for safe reuse after a fire. As guidelines for such post-fire investigations, the Architectural Institute of Japan has published "Guidelines for Fire Damage Diagnosis and Repair/Strengthening Methods, and Commentary," and the Japan Society of Civil Engineers has published "Guidelines for Diagnosis and Repair of Steel Bridges Affected by Fire." At Just, we conduct more precise investigations by incorporating our own non-destructive testing methods in accordance with these guidelines. Additionally, by applying non-destructive testing technology, it is also possible to estimate the tensile strength of steel materials and measure bolt axial forces on-site without damaging the components. Please feel free to contact us if you require our services. *For more details, please refer to the related links page or feel free to reach out to us.

Service for Existing Structures: Deterioration Investigation

Service for Existing Structures: Deterioration Investigation

Estimate the remaining lifespan of various pipes using a combination of sampling surveys! We will propose improvement methods based on crack investigations!

The lifespan of piping systems varies depending on their application and type, but deterioration of pipes, such as water leakage incidents, is a very serious issue for buildings. Our company estimates the remaining lifespan of various piping systems by combining non-destructive testing methods such as X-rays, endoscopy, and ultrasonic thickness measurement with sampling investigations through pipe removal. In crack investigations, we estimate the causes of concrete cracking and propose improvement methods. Additionally, we investigate decayed wood caused by termite damage or rainwater intrusion inside walls using X-rays and other inspection equipment. Please contact us if you require our services. [Survey Overview] ■ Crack Investigation ■ Wood Aging Investigation ■ Waterproofing Investigation ■ Equipment Deterioration Investigation ■ Piping Deterioration Investigation *For more details, please refer to the related link page or feel free to contact us.
