Commercial Epoxy Injection Services
Expert Solutions to Strengthen Structures and Improve SafetyEpoxy crack injection is a structural concrete repair method that bonds cracks together to restore monolithic strength. Using a two-part, high-strength epoxy resin, our technicians fill cleaned cracks with precision using a calibrated injection machine, a process trusted across commercial, industrial, and marine structures nationwide.
Compared to full concrete replacement, commercial epoxy injection services offer a faster, more cost-effective way to restore structural capacity. However, it's important to understand that epoxy injection repairs an existing condition. It does not eliminate the underlying cause of the crack. Identifying and correcting the root cause (settlement, load stress, thermal movement, poor drainage, etc.) is essential to prevent recurrence.
Proper crack cleaning is essential for effective results.
Epoxy pressure injection is a repair to an existing condition. It is not a solution to the cause of the problem.
When to Use Epoxy Injection vs. Polyurethane Injection
Epoxy injection is the right solution when a crack is dry, stable, and structural, meaning the repair needs to restore load-bearing capacity, not just stop water intrusion. If a crack is actively leaking or located in a wet environment, polyurethane crack injection may be the better fit, since epoxy will not cure properly in the presence of water. Our team evaluates crack width, moisture conditions, and structural requirements on-site to recommend the correct injection method for your project.
Additional consideration for every application:
- Inspect concrete integrity, surface temperature, moisture and crack contamination. Epoxy injection resins will not cure properly when introduced into the presence of water inside or weeping of moisture out of crack.
- Identify and solve the cause of the crack
- At periodic intervals, conduct sample testing of the machine injected resin to verify correct mix ratio and that samples have cured properly. Samples should be labeled and retained for QA/QC
- Select resin viscosity that is compatible with the width, depth, and size of the crack. Industry standards do not recommend injection of cracks wider than 3/8”
- Mechanically roughen length of concrete surface on each side of the crack to ensure epoxy paste bond. Use cap paste with excellent bond and create a positive seal.
- Select proper methods for removal of epoxy cap paste and ports to ensure the best possible aesthetic finish.

Frequently Asked Questions
Commercial epoxy injection is used to structurally repair cracked concrete in commercial, industrial, and marine buildings, restoring load-bearing capacity without the cost of full concrete replacement.
Cure time depends on resin viscosity, ambient temperature, and crack size, but most epoxy resins reach initial set within a few hours and full cure within 24 to 72 hours. Our technicians select resin systems suited to your job-site conditions.
Epoxy injection restores structural strength to the cracked section of concrete, but it repairs the existing crack, not whatever caused it. Long-term success depends on identifying and addressing the root cause (movement, load, settlement, etc.) alongside the injection repair.
Industry standards generally do not recommend epoxy injection for cracks wider than 3/8 inch. Wider cracks or larger structural deficiencies may require a different repair approach, such as structural concrete repair or carbon fiber reinforcement.
Yes. Epoxy Design Systems has completed over 5,500 repairs across the United States, along with international projects, since 1977.
Cost varies based on crack length, accessibility, structure type, and site conditions. Because epoxy injection is significantly less expensive than concrete replacement, most commercial clients see it as a cost-effective repair option. Request a quote for a project-specific estimate.
