We would like to introduce a case study of the "Water Shutter" that our company handles. Before the introduction of the water stop board, there were budget-related challenges such as "considering the introduction of a water stop board for flood prevention, but high-performance water stop boards are also expensive" and "the budget does not fit for individual installations." The "subsidy for the installation of water stop boards," which is widely implemented in areas prone to flooding, has various programs adopted by different municipalities. Customers considering flood prevention measures may want to check with their local municipality. 【Case Overview】 ■ Product Details: H377 (2-panel) ■ Building: Private residence ■ Installation Location: Garage opening ■ Region: Aichi Prefecture ■ Subsidy Details: Half of the installation cost of the water stop board (up to 300,000 yen) *For more details, please feel free to contact us.

• Water stop

◎ It can be applied to wet surfaces and underwater. There is no need to dry the surface. ◎ It is made of a resin-based sheet that is excellent in weather resistance. ※ Accelerated weather resistance test with a weather meter: approximately 30 years equivalent without cracks. ◎ The dedicated adhesive has good flexibility and adheres well to structures. Additionally, since no primer or other surface treatment is required, it reduces the time and effort needed for repairs. ◎ The fibrous material on the back of the sheet interlocks with the adhesive, making the attachment of the sheet very strong. (There have been no cases of peeling on-site after the sheet was manufactured.) ◎ A dedicated weep hole (check valve) can be installed on the sheet. ※ In areas where water seeps from joints, applying the sheet may cause the water to lose its escape route, potentially leading to uplift of the structure, expansion of cracks, or peeling of the sheet. By installing a weep hole, an escape route for the water can be created, preventing water from escaping from the structure. Registered as a new construction method by the Tokai Agricultural Administration Bureau. (Please check the link below.) It complies with quality standards as a material used for joint covering methods as per the Ministry of Agriculture, Forestry and Fisheries.
