A team of experienced ground professionals provides total support from the designer's perspective.

The ground business services of Inhabitant Business provide a one-stop solution from investigation to construction and warranty. We conduct ground surveys, analyze and determine results, prepare construction estimates, and then provide reinforcement work to the client. We also offer ground warranty as aftercare.

Additionally, ground warranty is automatically included. There are no exemptions due to slope angles, and we also address ground accidents caused by retaining walls; it is applicable to non-residential properties as well. This is a top-class ground warranty in the industry.
