"Fitting Bar" that significantly enhances the water-stopping ability of the stop water board.

By using the "fitting bar," you can reduce water leakage!

We would like to introduce our "Fitting Bar" that we handle. The water stop board uses the walls at both ends to prevent water intrusion. However, the ground and walls are often not at right angles, which can create gaps between the water stop board and the walls. Additionally, the water pressure on the wall side of the water stop board is lower compared to the bottom, which can lead to inefficient compression of the water stop rubber and water stop packing, resulting in leaks. Therefore, the Flood Guard F uses the "Fitting Bar." Compared to conventional products, the water stop capability has been significantly improved. 【Features】 ■ When using FG that utilizes the side walls for water stopping, there are no gaps. ■ When using FS that utilizes the back wall for water stopping, there are no gaps, enhancing the water stop effect. ■ By aligning FG, it is also possible to accommodate "steps." ■ The water stop capability has been significantly improved compared to conventional products. *For more details, please refer to the PDF materials or feel free to contact us.

We conducted a flooding test on the new product "Flood Guard F."

Calculate the average leakage amount from the mass of collected leakage water! Introducing the evaluation of the leakage test conducted.

"Flood Guard F" is a simple type of water stop board that has been certified after passing the evaluation of disaster prevention necessity, safety, and functionality at the 23rd Disaster Prevention Product Recommendation Review Meeting held by the General Incorporated Association for Disaster Prevention and Safety. We conducted a leakage test using this product and the "Flood Guard Asia Specification." We filled fresh water to a height of 51 cm, adjusted it to maintain that level, and confirmed the stability of the water level visually for more than one minute. After that, we collected the leakage from the collection point for one minute after the leakage amount stabilized, performing this collection three times. We calculated the average leakage amount from the mass of the collected leakage and converted it to an hourly rate, which was recorded as the leakage amount. Our company is committed to daily research and development to provide better products. [Test Subjects] ■ Flood Guard F: 2 units of FZ50, 1 unit of FT50, 1 unit of FG50, 1 unit of FGL50 ■ Flood Guard Asia Specification: 3 units of DZ50, 2 units of SG50 ■ Sandbags: 26 units *For more details, please refer to the PDF document or feel free to contact us.
