What is Epoxy Injection?

Epoxy injection is a method used to repair cracks in concrete structures. The process involves injecting a mixture of epoxy resin and a hardener into the crack, which then hardens to form a strong and durable bond that holds the crack together. The mixture is injected into the crack under pressure using specialized injection equipment. Once the epoxy has hardened, it bonds to the surrounding concrete and effectively seals the crack, preventing water and other contaminants from penetrating the concrete and causing further damage. Epoxy injection is typically performed by trained professionals and is usually done after the crack has been cleaned and prepped. It is commonly used for structural repairs such as foundations, beams, and columns, as well as for repairing cracks in floors, walls, and other concrete surfaces.

Advantages of Epoxy Injection

  • Strong and durable bond: Epoxy creates a strong and durable bond that holds the crack together, making it a reliable option for structural repairs.
  • Seals against water and other contaminants: Epoxy injection seals the crack, preventing water and other contaminants from penetrating the concrete and causing further damage.
  • Cost-effective: Epoxy injection is often considered a cost-effective option for repairing concrete cracks, especially when compared to other methods such as replacement or rebuilding.
  • Can be used for both interior and exterior repairs: Epoxy injection can be used for both interior and exterior repairs, making it a versatile option for various types of structures.
  • Can be used for both horizontal and vertical cracks: Epoxy injection can be used to repair both horizontal and vertical cracks, making it useful for a wide range of repair applications.
  • Low-Maintenance: Epoxy Injection repair is low-maintenance and long-lasting.
  • Can be used to repair complex cracks: Epoxy injection can be used to repair complex cracks, including those that are irregular in shape or size.

Epoxy Injection: When to be Used?

Epoxy injection is typically used when a concrete structure has developed cracks that need to be repaired. It is often considered as a suitable option for structural repairs, such as in foundations, beams, and columns, as well as for repairing cracks in floors, walls, and other concrete surfaces.

It can be used in a variety of applications, such as:

  1. Sealing cracks in foundations to prevent water infiltration and structural damage
  2. Repairs of concrete beams, slabs, and columns
  3. Repairs of spalls and delaminations in concrete structures
  4. Repairs of concrete floors and walls
  5. Sealing joints in concrete structures
  6. Strengthening of concrete structures
  7. Waterproofing of concrete structures
  8. Concrete restoration of historic or heritage buildings

In general, epoxy injection is used when the crack is actively moving, or when the crack is wider than a hairline and when the crack is not structural.

Epoxy injection is considered a cost-effective and efficient way to repair concrete and is often used in situations where the structure needs to be restored to its original strength and stability. It is important to note that epoxy injection is typically performed by trained professionals and is usually done after the crack has been cleaned and prepped.
