waterproof board

Abstract

This product is a waterproof board that prevents rainwater from entering through entrances and exits of underground passages and buildings when flooding occurs due to typhoons, heavy rain, etc. The waterproof board itself and auxiliary panels are formed by connecting multiple hollow aluminum alloy panels in the vertical direction. The waterproof board itself is provided with a removable auxiliary panel on the back side, and a groove on the front side into which the auxiliary panel is fitted. The waterproof board is manufactured to a width slightly longer than the width of the entrance opening into which it will be installed. When installing this product at an entrance opening, the back side is facing the interior of the building and the front side is facing the exterior of the building. When storing the product, the two auxiliary panels fixed to the back side of the waterproof board itself are fitted into the grooves on the front side to allow it to stand on its own.
