Gumron Fort Underground Waterproofing and Post-Construction Method (Civil Engineering and Underground Construction)
After the body is cast, a modified asphalt sheet is applied to ensure reliable waterproofing functionality (civil engineering underground and building underground waterproofing).
The "post-construction method" involves applying a waterproof layer after the concrete structure of an underground facility has been completed. After pouring the concrete, a primer is applied, followed by the attachment of "Gumron Fault." During backfilling after construction, protective materials (such as GS Protector) are applied to protect against damage during the backfilling process. This method is highly reliable as it allows for waterproofing to be applied directly to the concrete structure. It is necessary to secure a work area for waterproofing, making this method advantageous when there is ample land available. *For more details, please refer to the PDF document or feel free to contact us.*
