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.

Insight Systems - Before After

Riggins Construction & Management, Inc. was commissioned by Insight Investments, Inc. to design and build tenant improvements and exterior renovations for their Insight Systems Exchange division in Garden Grove.

This 44,000 square foot building received epoxy injections at the tilt-up walls and repairs to the concrete warehouse floors.  Four new windows were sawcut and reinforced into the north and west sides of the 7,000 square foot office area.  As a finishing touch, the exterior paint was made to match the corporate color scheme and new concrete entry ramp/stair was added to dress up the exterior and meet current HC/ADA accessibility requirements.

Two existing multi-fixture office restrooms were upgraded to ADA standards with new fixtures, partitions, countertops, and FRP (fiberglass reinforced paneling).  Four additional multi-fixture restrooms were added in the lobby and warehouse areas.  The lobby, halls, and break room were adorned with vinyl composition tile with splashes of red accent tiles also drawn from their corporate palette.

“We were impressed with the degree of customer service you provided in keeping us informed and involved throughout every stage of this project.  Your input and recommendations on various issues, proved invaluable.” ~ Richard Heard, President, Insight Investments, Inc.

The 37,000 square foot warehouse facilitates two computer equipment audit areas:  one for desktops and the other for laptops. Both were supplied with additional dropped fluorescent lighting, power cord drops, and compressed air line systems to audit tables to allow testing and repairs of their off-lease computer equipment for resale.
