Description

The present invention mainly relates to a device for preventing water from entering a building, which uses a sheet (hereinafter referred to as "sheet-type waterproof device").

A large amount of rain due to localized torrential rain, etc., cannot be treated by drainage facilities such as gutters, and floods often occur inside buildings. Traditionally, sandbags have been used to prevent flooding. However, preparing sandbags in advance requires a large amount of soil and a large storage area. Another problem is that sandbags are heavy and difficult to install. Therefore, devices have been developed that can be waterproofed without using sandbags.
