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.

Intense rainfall has increased by 1.4 times in the past 30 years! Awareness of disaster prevention on concentrated days.

Intense rainfall has increased by 1.4 times in the last 30 years! Introducing flood barriers and flood prevention measures. *Materials available upon request.

When you suffer water damage, it incurs significant costs for replacing machinery and furniture, as well as redoing wallpaper and flooring, and it takes time to resume operations in stores and factories. Recently, heavy rains that occur once every few decades have been observed across the country, causing extensive damage. After experiencing damage, it's too late to think, "If only we had taken measures back then..." In some regions, there are subsidy programs for the installation of flood barriers. If you have any questions about flood barriers (waterproof boards, tide boards) or flood prevention measures, or if you would like to request materials, please feel free to contact us. For the installation of flood barriers (waterproof boards, tide boards) "Flood Stopper" to protect your valuable assets from water damage caused by typhoons and sudden heavy rains, trust Asahi Construction Co., Ltd.! *For more details, please refer to the PDF materials or feel free to contact us.

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.

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.

Removable flood barriers to protect factories, equipment, and machinery from water damage【Flood Stopper】.

Removable flood barriers to protect factories, equipment, and machinery from water damage【Flood Stopper】.

Installation completed with a small number of people! Incredible water-stopping power with 2 locks! During normal times, it can be stored on the wall, so it doesn't get in the way!

When a factory is flooded due to typhoons, guerrilla rainstorms, or linear precipitation zones, materials, finished products, and production lines are submerged, leading to a halt in operations. Returning to normal operations 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. These products are selected from international airports, hangars, pharmaceutical factories, manufacturing plants, logistics warehouses, etc. This time, we would like to introduce two "flood prevention products"! 【Flood Stopper】 - The panel is very lightweight at 3kg per meter, making it easy for women to carry. - 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 simulate actual disaster conditions. 【Flood Sensor KAMEKER】 - By introducing it alongside the Flood Stopper, disasters occurring during late-night or holidays can be immediately detected. - When flooding is detected, it quickly sends the flooding status to registered stakeholders via LINE or email. - This enables a swift initial response to disaster management. - No complicated electrical work is required. *For more details, please refer to the PDF document or feel free to contact us.
