Simultaneous repair of the rear support Con! For repairing leaks and malfunctions occurring in bridge joints! Selected by the Ministry of Land, Infrastructure, Transport and Tourism for "Technology for Repairing Water Stop Sections of Bridge Expansion Devices"!

The "Ninja Seal Bridge Expansion Device Repair Method" is a cost-effective and simple technique using a two-component, room-temperature polyurea resin that suppresses water leakage by filling the gaps in the bridge expansion device and covering it uniformly. It utilizes a durable urethane-based resin material known as "soft stainless steel." No heavy machinery is required, and it can be easily and quickly applied even by those without specialized skills, allowing for simultaneous repairs of post-installed concrete. Additionally, since it does not involve fire, it reduces the risk of fire and burns. 【Features】 ■ Technology suitable for small-scale bridges ■ Can be applied by anyone ■ Applicable to straight butt joints ■ Can also accommodate slide joints and embedded joints (conditions apply) *For more details, please download the PDF or feel free to contact us.
