Fix your concrete panel cracks with epoxy injection.

How to Fix Cracks in Concrete Tilt-Up Panels with Epoxy Injection

Does your concrete tilt-up building have cracks? Are those cracks simply cosmetic? Is it just chipped paint? Chances are, it’s not.

Because both concrete and the earth tend to move, concrete tilt-up panels will develop cracks.

These cracks are not merely at the surface. They are not cosmetic.

Rather, they crack through the entire thickness of the wall panel. Thus the mnemonic: “cookies crumble, concrete cracks.” We call them “through-wall cracks.”

What are through-wall cracks?

Through-wall cracks not only compromise the structural integrity of a building but they’re a neon sign advertising water intrusion. And we know that’s not a good thing, right?

Epoxy Injection is a Structural Repair.

“What this does is welds the concrete back together, protects the rebar that’s running across the cracks, and waterproofs the building for water intrusion.” Art Dodge

This weld is a structural repair.  Once the epoxy is cured its strength is 15,000 pounds per square inch (psi). In fact, the weld is stronger than the concrete was originally.

What will epoxy injection do to my building?

I interviewed Art Dodge of Dodge Concrete Waterproofing Surfaces about the steps involved to structurally repair these cracks with epoxy injection.

Epoxy Injection: The Process

Here are the steps:

1. Strip off the paint two inches wide on each side.
2. Clean out the cracks.
3. Apply a pressure-seal resin over the face of the crack.
4. Every six inches, pressure inject epoxy at each entry port.
5. Heat and strip off surface of the epoxy flush with the concrete.
6. Patch, prime, and repaint the building.

Epoxy injection is a process that also works well to repair concrete that is starting to delaminate because of rusted rebar corrosion.
