Epoxy Injection

Low-Viscosity Structural Crack Repair System

Designed for cracks that require full-depth sealing, epoxy injection systems bond concrete from within—restoring structural integrity and stopping water intrusion.

​

Cracks that leak or allow moisture intrusion are often deeper than they appear. Surface repairs may hide the issue, but they don’t fix it.

​

Epoxy injection penetrates the full depth of the crack, bonding the concrete back together and creating a long-term structural repair.

When to Use This System

Epoxy injection is ideal for non-moving cracks in poured concrete foundation walls, especially when the goal is to seal and structurally restore the crack.

​

It is commonly used for vertical or diagonal cracks, leaking foundation walls, and cracks that require full-depth repair rather than surface patching.

What This System Does

Epoxy injection works by filling the crack internally, restoring strength and preventing further intrusion.

​

  • Seals cracks from the inside out

  • Stops water intrusion

  • Restores structural continuity

​​

Unlike surface repairs, this system creates a bond within the concrete itself—providing a permanent solution for non-moving cracks.

How It Works

The system is designed for efficient installation in the field:

​

  1. Prepare the surface and clean the crack

  2. Install injection ports along the crack

  3. Seal the surface to contain the epoxy

  4. Inject low-viscosity epoxy until the crack is fully filled

​​

Once cured, the epoxy creates a solid internal bond that reinforces the structure.

Built for Real Jobsite Conditions

CrackGuard epoxy injection systems are based on field-proven methods used by Structural Reinforcement Solutions in real-world applications.

​

They are designed for contractors who need reliable performance without unnecessary complexity.

Need Structural Reinforcement Instead?

If the crack shows signs of movement or requires reinforcement, a carbon fiber system may be the better solution.

Dealing with Bowed Walls?

If the wall is actively bowing or moving inward, a stabilization system may be required.
