Company information
Yamashita Kogyo Co., Ltd. smoothly manages the process from accepting ground surveys necessary for the application of the defect warranty system to the completion of ground improvement and reinforcement work, also taking responsibility for the added trust of ground warranty. ■ "Defect Warranty" A defect warranty is a promise to "compensate for losses incurred when a defect is found." When a defect warranty is provided, if a "defect" is identified in a major structural part of the house and repairs are made, insurance money will be paid. A ground survey is required when applying for insurance to fulfill the defect warranty. Our company conducts everything from proposals for the necessary ground surveys and ground improvements for the defect warranty to the actual execution of the work. * Based on the data obtained from the ground survey, we will propose suitable ground reinforcement and improvement work by utilizing our accumulated experience while considering various ground characteristics. * For housing suppliers such as construction companies and real estate firms who are wondering "What should we do?" regarding housing defect warranties and ground surveys, please feel free to contact us.
