Polyurea Injection Grout
Polyurea Injection Grout (Polyurea Grouting Materials) is a high-performance polymer injection grout characterized by excellent waterproofing, high elasticity, chemical resistance, high solid content, and non-shrinkage properties. Its sealing performance surpasses that of conventional sealants. Additionally, the product offers high tensile strength and elongation atbreak, enabling it to bridge various structural cracks, pavement cracks, and voids. It effectively addresses leakage and recurrent leakage issues caused by
expansion joints, contraction joints, and connection joints.
Single-component / Eco friendly / OEM Accepted
APPLICATION RANGE
1.Civil Engineering: Polyurea sealant is used in water conservancy projects such as dam reinforcement and seepage prevention, enhancing safety
2.Subway Tunnels: In tunnel construction, polyurea grouting fills gaps between tunnel linings and surrounding rocks, preventing water leakage and ensuring safety
3.Bridge Repair: Polyurea sealant, with its fast curing and high strength, is ideal for repairing bridge cracks and restoring load-bearing capacity
4.Industrial and Civil Buildings: Polyurea sealant is used for waterproofing in basements, roofs, and walls, protecting the building structure.

CUSTOMIZATION SERVICE
Customization is available for product color, packaging design, and package sizes.
Note:
1.For filling joints or pavement cracks, the product can be poured directly into the crack.
2.During application, the substrate temperature must be at least 3°C above the dew point.
3.When injecting the product with a grouting machine, a polyurea-specific injection machine or a machine with a power rating of 1500W or higher must be used. Otherwise, the product may not be properly dispensed.
4.When working in confined spaces, ensure adequate ventilation is maintained.
5.Once the pail is opened, it is recommended to use it up within 3 to 5 days, provided the lid is tightly resealed. Otherwise, the product will cure upon exposure to air.
