Safe, Secure and Reliable

We provide detailed support services such as inspection of installation sites, performance verification, etc.

●Ground strength inspection
The Swedish sounding test (JIS A 1221: 2013) is used to confirm the strength of the ground where the installation is planned.

●Performance check
Installers can check the performance at the installation location using the designated small testing machine “Techno Tester DT-50TCL”. Installers can easily perform a design load confirmation test in advance to verify the quality for formal installation.

●Construction technology examination certificate
The direct earth method has obtained a construction technology examination certificate (examination organization, Better Living: BL examination certificate-014).
