Sealing technology

Unleashing the performance of buildings! Introducing advanced sealing technology that protects structures from wind and rain.

Masaru's sealing business strength lies in its track record of handling construction for approximately 70% of the high-rise buildings in Tokyo and its proposal capabilities backed by technical expertise. Our "sealing technology" fills joints and gaps with materials such as resin and synthetic rubber to enhance the building's performance. We conduct research and proposals on joint structures to protect buildings from major threats like earthquakes and typhoons, ensuring that even if the building itself deteriorates and its functions decline, issues such as water leakage do not occur. We can select sealing materials suitable for various exterior components and joint structures, achieving excellent sealing waterproofing. 【Features】 ■ Technology to enhance building performance ■ Providing suitable solutions from proposals to quality control ■ Proposals for new joint structures ■ Quality control by approximately 400 workers with first-class waterproofing skills and construction management engineers ■ Waterproofing work carried out manually by workers, one by one *For more details, please refer to the PDF document or feel free to contact us.
