The “Sheet,” which can be set up in one-tenth the time of sandbags, can be stored compactly and kept ready for use.

Are you prepared to deal with flood damage caused by typhoons and guerrilla torrential rains? Are you prepared to respond immediately in case of an emergency?
Japan is a rainy country, and according to statistics, it rains once every three days. Recently, there have been many abnormal weather events, and as we have become accustomed to hearing the term “guerrilla downpour,” heavy rainfall causes damage in many areas every year.
The frequency of “extremely heavy rain,” or rainfall of 50 mm or more per hour, has been increasing every year, and in 2019 and 2020 it broke the record for the most consecutive years of observation. In case of emergency, the most commonly used flood prevention tool is a sandbag. However, sandbags are difficult to keep on hand, take time to set up, and require skill to set up correctly. This article introduces the “Delta Panel,” a new flood prevention tool that can replace sandbags. The “Delta Panel” is compact, easy to store, and can be easily set up by anyone in one-tenth the time of sandbags. This is a must-see for those in charge of disaster prevention at municipalities and store operators such as convenience stores.

Little Known? Weaknesses of sandbags during flooding damage

When flood damage occurs, sandbags are the first flood prevention tool that generally comes to mind. Of course, sandbags are effective to a certain extent, but in fact, they have their weaknesses.

• It is difficult to keep sandbags on hand at all times
• There is a process to prepare the soil to be packed inside, and it takes time to prepare for installation.
• Installation work also takes time (about 100 minutes for a 4m width)
• Requires experience and skill as water leaks easily if not installed correctly.

It is difficult to keep sandbags on hand at all times

Does your facility or store keep sandbags on hand? The answer is probably no. Even if you can prepare “sandbags,” it is not easy to keep a large amount of soil on hand to fill them, especially in urban areas.

 

Takes time to prepare for installation, such as preparing soil to be packed inside.

Then, when the time comes, the soil will have to be brought in from another location. There is no such time window after actual flooding occurs.

 

Installation work also takes time (about 100 minutes for a 4m width)

When the sandbags and soil are ready, the work finally begins. Filling, sealing, and stacking the bags with soil is done entirely by hand. It takes about 100 minutes for two workers to set up a 4-meter-wide wall of sandbags about 45 cm high.

 

Leaks can easily occur if not installed correctly, requiring experience and skill.

Furthermore, it is not easy to obtain sufficient water sealing effect when sandbags are placed by those who lack experience and skills.

 

If they are not stacked in the correct manner and the gaps are not filled, water can leak through the gaps. Installing sandbags requires skill and experience.

Delta Panel, a new flood prevention tool that is compact and easy and replaces sandbags (patent pending)

The “DELTA PANEL” is a flood prevention tool that covers the weak points of sandbags and realizes regularity, shortened installation time, and simplified work. DELTA PANEL” is a revolutionary flood prevention device that replaces sandbags by using lightweight, highly durable sheets to build flood barriers. Simply by installing it at the entrance to a building or basement that is at risk of flooding, water can be prevented from entering. The main features of the device are its light weight, compactness, and ease of installation by anyone in a short period of time.

• Lightweight, compact and always ready to use
• Quick and easy installation; no other materials required
• High water resistance without experience or skill
• Economical for repeated use
• Sheet can be used on uneven installation surfaces

Lightweight, compact and always ready to use

Each delta panel, 60 cm high and 110 cm wide, weighs only 2.5 kg. Since each bag of sandbags weighs approximately 15 to 20 kg, the DELTA PANEL is overwhelmingly lightweight in comparison. In addition, since DELTA PANEL is made of sheets, it can be rolled up small and folded for storage when not in use. It can be compactly and permanently stored in small stores and residences.

Quick and easy installation; no other materials required

To build a floodwall about 45 cm high by 4 m wide using sandbags, it takes about 100 minutes for a two-man operation. With delta panels, it takes 10 minutes. The work is completed by simply raising the delta panels and inserting the pipes, and it takes only one-tenth of the time to build a floodwall of the same size. Also, no other materials, such as soil, need to be prepared, so no preparation time is required.

High water resistance without experience or skill

Since DELTA PANELS are sheet-like and catch flooding water on their “surface,” even if they are installed by people without skill or experience, gaps will not occur, and a high level of waterproofing can be achieved. The amount of water leakage is about 1/40* compared to sandbags.

Economical for repeated use

After use, the delta panel can be dried and disassembled for storage again. This eliminates the need for disposable panels each time, and is extremely economical.

The sheet can be used on uneven installation surfaces.

Unlike sandbags and other flood control panel products, the Delta Panel is in sheet form, so it conforms well to the surface where it is installed and provides firm flood protection.

Is the delta panel strong enough?

I understand the advantages of the sheet form, but is it durable?” DELTA panels are made of thin sheets, and from their appearance, you may be concerned about their durability.
However, the following mechanisms ensure that even sheets can withstand sufficient water pressure.

 

Here is a photo of an actual water pressure test. Its stable waterproofness can be confirmed.

It also has high tearing strength and can withstand 70 to 80 kg of force. This is approximately five times stronger than sheets used for general tents.

 

It is designed for use in flooded urban areas, and is not likely to be damaged unless it is plunged by a sharp, heavy object, such as driftwood, for example.

summary

In preparation for the increasing damage caused by typhoons and torrential rains, we introduced the “Delta Panel,” which allows anyone to quickly and easily build a flood barrier when the need arises.

• Lightweight, compact and always ready to use
• Quick and easy installation; no other materials required
• High water resistance without experience or skill
• Economical for repeated use
• The sheet can be used on uneven installation surfaces.

With these excellent features, we hope that you will always have a Delta Panel on hand to minimize damage in the event of an emergency. For more information about Delta Panel, please contact us at the following
