Water leakage and water stopping measures for joints and cracks in concrete structures.

A water stop method to block the leakage path and a water diversion method to collect and direct the leakage to drainage facilities such as road surfaces, addressing leakage from concrete structures.

"Emergency Measures for Underground Structures (Water Leakage and Delamination)" is a method for addressing water leakage from joints and cracks in concrete structures, which can be broadly categorized into water stopping methods and water guiding methods. We quickly propose appropriate responses based on the condition of the structure assessed during site investigations. We also specialize in short nighttime work within operational lines, such as subways. We respond swiftly to water leakage and delamination within underground structures. Please feel free to contact us when needed. 【Water Stopping Method Features】 ■ A method that involves drilling to block the water leakage path at the leaking joint or crack, followed by injecting water stopping material under high pressure to seal the water path. ■ Can be applied to fine cracks. ■ Uses an electric pump that is compact and easy to transport. ■ Applicable in narrow spaces. 【Applications】 ■ Water leakage from concrete structures.
