Hybrid Basement "Iron Wall"

A method for constructing a basement by embedding steel formwork into concrete to create a waterproof layer [Patent No. 6836808] ★ If the formwork is made of ultra-thick steel plates, it can also be used for nuclear shelters!

The "Hybrid Basement - Iron Wall" is a patented construction method that involves embedding steel formwork, which has been welded on-site, into concrete to create internal waterproofing. The interior surfaces of the reinforced concrete basement—floor, walls, and ceiling—are completely enclosed with steel plates that do not allow water or moisture to pass through. Therefore, it is possible to create a "basement that does not require a dehumidifier," as water and moisture contained within the concrete structure do not leak into the interior. This patented method eliminates the need for external waterproofing or double walls and does not accumulate groundwater, making drainage pumps unnecessary. ★Expected Uses★ - A "comfortable basement" with no worries about leaks - A "nuclear shelter" that is safe even with high groundwater levels → Its strength lies in not requiring drainage pumps even during prolonged power outages! - A "defense facility" to protect the country → By using extremely thick steel plates for the steel formwork, it is possible to dramatically enhance the strength of the concrete structure! ★Order Types★ - Design of buildings utilizing the hybrid basement - One-stop provision of steel formwork "Iron Wall" - Construction of hybrid basement method buildings by partner companies - Licensing of the patent *For more details, please download the PDF or contact us.
