ハマキャスト List of Products and Services

This is an example of a building exterior renovation using the Hamatex Net Anchor Method and Hamacast JX on existing porcelain tiles. During the investigation, approximately 30% of the exterior tiles were found to be loose, and several had already fallen off. Additionally, the building is adjacent to the JR Chuo Main Line tracks and a pay parking lot, making it a highly public space frequented by many students daily, necessitating urgent action. Concerns were raised that a conventional renovation might lead to a recurrence of similar issues, which is why our 20-year warranty exterior renovation system was adopted. This case maximizes the value (quality, aesthetics, warranty) of our services for a highly public building. [Case Overview] - Product Name: Hamatex Net Anchor Method + Hamacast JX: 3,684.2 m² - Project Name: Exterior Renovation of Ohara Gakuen Kofu School - Location: Kofu City, Yamanashi Prefecture - Substrate: Porcelain Tile *For more details, please feel free to contact us.*

We would like to introduce the feedback from the "APA Group Osaka Branch, Western Japan CM Division" regarding the renovation of a hotel located in Kadoma City, Osaka Prefecture. 【Interview Content】 Q1: Please tell us about the circumstances leading up to your decision to adopt our services. → We acquired a hotel with a distinctive exterior wall color and planned an expansion. In order to operate the two buildings as a unified entity, we considered designing a cohesive appearance to resolve the disparity between the old and new structures. At that time, the long-term warranty of 20 years, exemption from regular reports, and the ability to reduce running costs and streamline management became the decisive factors for our adoption. Q2: How did you feel during the actual construction process? → For the existing building, the construction was carried out by specialized contractors from the manufacturer starting from the substrate treatment stage, which provided a sense of security. Q3: After the completion of the construction, what changes have you experienced? → There was no noticeable difference in the exterior walls between the existing building and the expansion, and we received evaluations from various stakeholders both inside and outside the company stating that it is indistinguishable from a new building. *For more details, please download the PDF or feel free to contact us.
