Boxwall: A flood barrier that easily replaces sandbags to protect valuable assets from sudden heavy rain and flooding, with no construction required for installation.

last updated:Aug 17, 2026

Not only as a BCP measure, but also optimal for sudden heavy rain and flooding risks. It is a flood barrier that requires no pre-construction and can be installed in a short time to protect equipment and assets.

Boxwall is a water barrier that requires no construction or tools, designed to stop flooding using the weight of water and water pressure. It operates on the principle that "the more water it receives, the more the body is pressed down onto the ground, increasing its water-stopping power." Instead of stacking like sandbags, it simply connects and rests on the ground to protect assets from flooding. It is used to prevent water intrusion at entrances of buildings and apartments, parking lots, and within facilities, and is also ideal for preventing chemical spills from factories to the outside. This next-generation water barrier can be quickly deployed to respond to localized heavy rain. ◆ Easy and quick installation for anyone! It can be easily installed without specialized knowledge or prior construction by simply connecting the joints of the main body. It allows for rapid response even to sudden flooding from torrential rain or typhoons. ◆ Operable with a small number of people and requires minimal space! Unlike sandbags, it requires no preparation and is not as heavy as metal water barriers, allowing for installation by a small team. After use, it can be rinsed and reused. It can be stacked for storage, taking up minimal space. ◆ Various applications and locations supported with options and lineup! With options for water levels of 50cm and 100cm, it can accommodate a wide range of locations, and options for outside corners and inside corners are also available. It can be used according to the installation environment.
