You who protect yourself.

Our home's breakwater Compact water stop board, you who protect yourself.

This is a compact water stop board. It is easy to install, allowing you to simply place it at your entrance to protect your home or office from flooding. (Water pressure-based water stopping) The sponge (packing) on the bottom surface is made of a material that increases water-stopping ability when compressed. When water flows and accumulates on top of the water stop board, the sponge on the bottom compresses due to the water pressure, achieving high water-stopping capability. Additionally, it stays in place without being swept away by a certain amount of water flow due to being pressed against the bottom by the water pressure. (Strong and highly water-stopping connection structure) The connection of the water stop boards does not require special parts like clamps; it is done through an interlocking claw structure between the main bodies. The original design shape not only facilitates easy installation but also considers sufficient strength. Furthermore, the sponge at the overlapping parts of the water stop boards maintains a compressed state, enhancing water-stopping ability. - Instead of sandbags: The water-stopping capacity is one thirty-third that of sand (does not guarantee complete waterproofing). - Lightweight and easy to install: Weighing 1.5 kg per board, it is easy to carry and install. - Can be stacked for storage: Neatly stored! After use, it can be stacked for compact storage.

The Exstopper is a product that enhances the water-stopping ability and workability that were problematic during the water replacement phase of the conventional method. It fixes the water-stopping plate inside the pipe and drains using a temporary pipe.

【Examples of Water Stop Board Installation】Same water stop performance regardless of who installs it!

Just slide the panel into the frame! Anyone can install it using the same method, so you can install it with confidence.

We would like to introduce a case study (feedback) of the "Water Shutter" that our company handles. There have been concerns that the currently used flood barriers are misaligned due to different installation positions by various individuals, and issues such as excessive leakage from the installed barriers, which were not properly secured. "After introducing the Water Shutter, we can insert the panels along the frame, so there is no misalignment or increased leakage due to different individuals. Anyone can install it with the same method, providing peace of mind." [Case Overview] ■Challenges - The currently used flood barriers can be easily installed with magnets or by turning a handle, but there are concerns about misalignment due to different installation positions by various individuals. - When it seemed that there was excessive leakage from the installed barriers, it turned out that the panels were misaligned and not securely fixed. ■Reasons for Adoption - Simple operation of inserting panels along the frame. - No misalignment or increased leakage due to different individuals. *For more details, please feel free to contact us.

【Case Study of Water Stop Board】 Installation is possible without removing obstacles in front of factory shutters.

【Case Study of Water Stop Board】 Installation is possible without removing obstacles in front of factory shutters.

It can be flexibly proposed since it can be adapted from the design according to the installation location!

We would like to introduce a case where our "Water Shutter" was implemented at a certain factory in Gifu Prefecture. There were instances where warning poles were installed in front of the factory's shutter, but with conventional products, they had to be removed. During the implementation, we were able to avoid the poles and other obstacles using corner support posts, which eliminated the need for unnecessary construction arrangements. 【Case Overview】 ■ Challenges - Warning poles were sometimes installed in front of the factory's shutter, necessitating their removal with conventional products. ■ Reasons for Adoption - We were able to avoid the poles and other obstacles using corner support posts, so there was no need to arrange for unnecessary construction. *For more details, please feel free to contact us.

[Case Studies of Water Stop Boards] We propose various storage solutions that save space!

[Case Studies of Water Stop Boards] We propose various storage solutions that save space!

Utilize small spaces and dead spaces for storage! Waterproofing is also perfect.

We would like to introduce a case study of the "Water Shutter" that our company handles. We have received the following opinions regarding the storage location of the product: "Conventional water stop boards from other companies have handles on the front panel, making it impossible to stack them for storage and taking up space. Therefore, we were considering a product that could be stored more compactly. It would be reassuring to have a cover for outdoor storage." "It can be stored using limited spaces or dead spaces, so there's no need to worry about storage locations!" You want to store the water stop board close to where it will be installed, right? The Water Shutter effectively addresses such concerns. *For more details, please feel free to contact us.

Flood prevention measures for medical facilities and more with flood stoppers! [Case study available]

Flood prevention measures for medical facilities and more with flood stoppers! [Case study available]

NETIS acquisition! Introducing the voices of hospitals that actually experienced flooding damage! Preventing failures of expensive medical equipment, facilities, elevators, etc., caused by flooding with flood barriers.

Flood prevention measures for medical facilities are very important. The Flood Control Act has been revised, making the creation of evacuation plans and the implementation of evacuation drills mandatory, which were previously only efforts. Particularly in medical facilities, important medical equipment is located underground, so if rainwater flows into the facility due to sudden heavy rain, it could lead to very serious accidents. By using flood barriers, waterproof boards, and tidal barriers known as "flood stoppers," we can prevent (or delay) flooding damage inside the building, allowing sufficient time for evacuation. We have included voices from hospitals that were affected during the heavy rains in western Japan, so please take a moment to read them. [Customer Voices (Excerpt)] ■ All paper items such as books, files, and medical records became unusable due to flooding. ■ We thought we would be fine since the disaster prevention equipment was on the roof, but when the first floor flooded, we could not use the emergency power supply, elevators, escalators, or facility functions, and the hospital was completely unable to operate. *For more details, please download the PDF or contact us.
