Flood prevention measures that replace sandbags, our home's breakwater. The "Mizukaramamorukun" water stop board easily installed to reduce flooding in homes and facilities.

This is a water stop board that reduces water inflow with high-level waterproof performance, replacing sandbags. It is easy to install and can be set up in a short time, allowing for quick measures against sudden heavy rain or flooding. Lightweight and compact, it is convenient for transport and storage, making it ideal for disaster prevention in small facilities. By connecting multiple boards, it can also accommodate a wide range of openings. 【Water Stop by Water Pressure】 The bottom packing uses a material that increases its waterproofing ability when compressed. As water accumulates, the sponge at the bottom is compressed by water pressure, providing waterproof performance. Additionally, it is pressed against the ground by water pressure, allowing it to remain in place even with a certain amount of water flow. 【Strong and Highly Waterproof Connection Structure】 The connection of the water stop boards does not require special parts and is done using a claw structure. This not only ensures good workability but also takes strength into consideration. Furthermore, the sponge at the overlapping parts of the water stop boards is maintained in a compressed state, enhancing waterproof performance. ◆Features◆ - High waterproof performance: Leakage is 1/33 of that of sandbags, achieved through water pressure. - Easy installation: Four boards can be set up in 30 seconds, and they are lightweight for easy transport. - Neat storage: Can be stacked compactly for storage. - Versatile application: Reliable waterproof measures can be achieved with dedicated adjustment boards and sponges.
