Case Presentation
Junlong Polyurea Grouting Compound, manufactured under Junlong's stringent environmental standards, is a high-performance, single-component polymer grouting solution formulated from polyurea emulsion through scientific processing. With high solids content, non-shrinking properties, and hydrophilic reactivity, this product delivers superior leak sealing performance compared to conventional sealants. It also exhibits high tensile strength and elongation, enabling coverage of severe cracks. This effectively resolves water seepage and recurrent leaks in structural cracks such as deformation joints, expansion joints, and construction joints, making it an ideal new-generation leak sealing grout. Suitable for leak sealing and grouting in all concrete structures such as underground engineering, subways, tunnels, culverts, and underground utility tunnels. Particularly effective for leak sealing grouting in structures subject to significant vibration and deformation, including shield tunnel segments, post-pour joints, expansion joints, and deformation joints.
