Surprisingly unknown? The difference between linear precipitation zones and guerrilla heavy rain *Materials available.

Surprisingly unknown? The difference between linear precipitation zones and guerrilla heavy rain *Materials available.

As a result, there is a risk of flooding in the building! Introducing two heavy rainfalls.

"Linear precipitation zones" and "guerrilla heavy rain" are both related to heavy rainfall, but their meanings are slightly different. The difference between the two lies in the size (extent) of the clouds and the duration of the precipitation. One thing to be careful about is that when comparing these two, it is a mistake to let your guard down just because guerrilla heavy rain tends to stop quickly. Localized heavy rain can temporarily paralyze drainage systems, causing water to accumulate on the streets, which may ultimately lead to flooding in buildings. Recently, information about heavy rain has become more accessible through news and social media, so when you come across these terms, it might be a good idea to check the flood prevention measures at your workplace or home and prepare in advance. For the installation of flood barriers (waterproof boards, tide barriers) "Flood Stopper" to protect your valuable assets from flooding damage caused by typhoons and guerrilla heavy rain, please leave it to Kyokujitsu Construction Co., Ltd.! *For more details, please refer to the PDF document or feel free to contact us.

One small watermelon! Lightweight and durable water immersion stopper *Materials available.

【NETIS Acquisition】Despite being lightweight, it excels in durability and water resistance! Introducing our flood stopper.

To give you an idea of how much 3 kg weighs, it is roughly equivalent to three 1-liter bottles of milk, one small watermelon, or six 500-milliliter plastic bottles, which is a weight you might carry during your regular shopping. It can be easily assembled by women, providing peace of mind. Please feel free to contact us.

Is the number of heavy rainfalls increasing year by year? *Materials are being distributed.

Is the number of heavy rainfalls increasing year by year? *Materials are being distributed.

In the long term, there is a trend of increase! Please feel free to consult us about measures such as water stop boards and automatic waterproof grilles.

It seems that the number of heavy rainfalls each year is increasing year by year. The Japan Meteorological Agency has been compiling data on precipitation from 51 locations, including weather stations and observatories, since 1901, counting the occurrences of daily precipitation of 100 mm or more and 200 mm or more on a yearly basis. Looking at the results, both categories show a long-term increasing trend. I believe the probability of heavy rain in your area is not low. Please feel free to consult us about measures such as water stop boards and automatic waterproof shutters. For the installation of water stop boards (waterproof boards, tide boards) "Flood Stopper" to protect your valuable assets from flooding damage due to typhoons and sudden heavy rains, please leave it to Kyokujitsu Construction Co., Ltd.! *For more details, please refer to the PDF document or feel free to contact us.

Useful for advance preparation! About the flood prediction area map *Materials are currently being distributed.

To be useful for prior preparations, areas expected to be flooded in the event of heavy rain are displayed!

In Tokyo, we are raising awareness of the risk of flooding due to heavy rain and have published a "Flood Prediction Area Map" that indicates areas expected to be flooded in the event of heavy rainfall, to assist with preparations in advance. You can learn about dangerous locations (areas expected to be flooded) and the level of risk (anticipated flood depth) when heavy rain occurs. Although this information is specific to Tokyo, we encourage you to use it as a reference and consider the introduction of "Flood Stoppers" and "Automatic Waterproof Louvers." For the installation of flood barriers (waterproof boards, tide boards) known as "Flood Stoppers" to protect your valuable assets from flooding damage caused by typhoons or sudden heavy rain, please leave it to Kyokujitsu Construction Co., Ltd.! *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Responding to BCP formulation requests from automobile manufacturers with water stop boards.

[Case Study] Responding to BCP formulation requests from automobile manufacturers with water stop boards.

Lightweight, quick, easy, and convenient flood prevention product compared to sandbags: Folding flood barrier F-shield.

Mr. Yamamoto is responsible for the overall safety management operations of the company at the Safety and Environment Department of Special Spring Industry Co., Ltd. "There are first-class rivers, the Inagawa River and the Darokugawa River, flowing near our factory, and there is a risk of these rivers flooding when typhoons or linear precipitation zones occur. In fact, a major typhoon passed through Hyogo Prefecture in 2018, and at that time, the situation was very close to a river flood. Therefore, it was necessary to present a sufficient BCP (Business Continuity Plan) to our customer, the automobile manufacturer, in preparation for potential river flooding." "The foldable water stop board F-shield is lighter than sandbags, making it easy to transport and set up. Unlike sandbags, there is no need for the cumbersome task of filling or emptying water; it can be easily set up and taken down by simply locking the fittings." A new disaster prevention warehouse has been established right next to the factory's main gate, where the foldable water stop board F-shield is stored, ensuring that it can be set up immediately in case of an emergency. "I would like to win the trust of our customer, the automobile manufacturer, by presenting a sufficient BCP (Business Continuity Plan) in preparation for river flooding."

Stop water board (Dam Easy)

Stop water board (Dam Easy)

Maintains the aesthetics of the installation area, suitable for the protection of narrower areas such as residential buildings, facilities, and underground space entrances!

This is a water barrier from Ireland, featuring excellent design and a unique mechanism. It is expandable horizontally and enhances water tightness by inflating rubber tubes with a built-in pump. Compact and lightweight, it is easy to carry and requires minimal storage space. Additionally, there is no need for permanent rails for installation, which does not affect the aesthetics of the area.

Our product can be installed in various locations, and we provide support from the design stage. Please feel free to contact us if you have any requests. 【Case Overview】 ■ Issue: Measures are necessary due to the maximum flooding height of 3 meters and the increase in disasters. ■ Product Details: H2975 (18-panel) ■ Installation Location: Opening of a concrete retaining wall ■ Reasons for Adoption: - Few manufacturers can handle up to approximately 3 meters. - A specialized manufacturer with extensive experience. *For more details, please refer to the PDF document or feel free to contact us.

Protect yourself from water damage! Lightweight and strong! Removable water stop board [Water Stopper]

Protect yourself from water damage! Lightweight and strong! Removable water stop board [Water Stopper]

Installation completed with a small number of people! Incredible water-stopping power with 2 locks! Storage is wall-mounted, so it doesn't get in the way! [NETIS registered product]

When buildings are flooded due to typhoons, guerrilla rainstorms, or linear precipitation zones, daily life comes to a halt, and returning to normalcy requires a tremendous amount of money, time, and effort. Since the sources of flooding, such as typhoons and guerrilla rainstorms, can be predicted in advance, it is possible to minimize damage if appropriate measures are taken. The "Flood Stopper" is very lightweight at 3 kg per meter, making it easy to carry! It exhibits high water-stopping ability by locking it in place. When not in use, it can be stored on the wall, so it doesn't get in the way. We also conduct impact resistance tests that are close to actual disaster conditions. It is chosen by international airports, hangars, pharmaceutical factories, manufacturing plants, logistics warehouses, and more. Additionally, by introducing the "Flood Sensor KAMEKER," disasters occurring during late-night hours or holidays can be immediately detected, allowing for quick information sharing with relevant parties. Moving to assess damage during a disaster is extremely dangerous. With the Flood Sensor KAMEKER, when flooding is detected, the flooding status is quickly communicated to pre-registered contacts via LINE or email. This enables a rapid initial response to disaster management. Complicated electrical work is also unnecessary.
