Concrete cracks are physical structural changes caused by the interaction of internal and external factors within a concrete structure. Cracks are a major cause of reduced load-bearing capacity, durability, and waterproofing in concrete structures. Different treatment methods are typically used for different types of cracks.
1 : Epoxy Resin Crack Filler System: A two-component modified epoxy low-viscosity liquid adhesive, characterized by low viscosity, low heat release, long pot life, and simple filling process.
2 : Epoxy resin filler: This sealant can be injected into micro-cracks as wide as 0.1mm, exhibiting good aging resistance and resistance to various media (acids, alkalis, water).
3 : It contains no volatile solvents and does not shrink during curing.
4 : It possesses excellent toughness and impact resistance after curing.
5 : With formula adjustments, it can be used for underwater crack filling.
