Analysis of PCBs in coatings

For coatings containing harmful substances! Our technicians are available 365 days a year.

At Kankyo Co., Ltd., we offer "analysis of PCBs and other substances in paint films." In the past, harmful substances were used in paints for steel structures such as bridges, sluices, and tanks. Before conducting peeling work on paint films during repainting projects, it is necessary to investigate the paint films to confirm whether they contain harmful substances. If the investigation reveals the presence of harmful substances, proper safety management during construction as stipulated by the Occupational Safety and Health Act and storage or proper disposal as designated for special controlled industrial waste under the Waste Management Act is required. Please leave the analysis to us. 【Standards for Industrial Waste】 ■Lead: 0.3 mg/L ■Chromium: 1.5 mg/L ■PCB: 0.003 mg/L *For more details, please refer to the PDF document or feel free to contact us.

Surface wave exploration services

For ground surveys of residential land and development sites, as well as levee surveys of rivers and investigations of cavities and looseness.

Among the elastic waves that propagate through the ground, waves that travel along free surfaces such as the ground surface are called surface waves. These waves have different propagation paths depending on their wavelength, resulting in variations in frequency and speed according to the S-wave velocity structure of the ground. Our company conducts surface wave surveys to derive the S-wave velocity structure from the way this dispersion occurs. The S-wave velocity structure can be converted to other physical property values (such as N values). Please feel free to contact us if you have any requests. 【Features】 ■ Excellent super vibration efficiency ■ Analysis diagram of two-dimensional cross-section *For more details, please download the PDF or feel free to contact us.

Rockfall Stability Automatic Diagnosis System

Up to four rockfall surveys can be conducted in a single measurement! Quickly assess stability based on rockfall vibrations.

The "Rockfall Stability Automatic Diagnosis System" is a diagnostic system that can quickly assess the stability of rockfalls using their vibration characteristics. The vibration characteristics of rockfalls can be obtained by comparing rockfall vibrations with ground vibrations (vibrations of the foundation). The vibrations of the rockfall and the foundation are measured using high-sensitivity accelerometers, supporting traditional qualitative rockfall surveys. 【Features】 ■ Capable of measuring up to four rockfall locations simultaneously against one foundation location ■ Gypsum is used for the installation of accelerometers ■ A handy measuring device (approximately 10 kg) enables speedy surveys ■ The built-in computer in the measuring device allows for on-site evaluation of rockfall stability ■ The necessary vibration sources can be adequately provided by miscellaneous vibrations from vehicles traveling on nearby roads, etc. *For more details, please download the PDF or contact us.
