Epoxy Injection Services
Cracks in structural masonry may look minor on the surface, but they compromise more than just appearance. Left untreated, voids and separations reduce the stability of walls, columns, and load-bearing units.
Epoxy injection is a highly targeted method for restoring internal integrity: filling voids, sealing cracks, and reestablishing cohesion in concrete masonry systems. The process not only prevents further deterioration but also strengthens the structure so it can continue performing its critical role safely and reliably.
How Repairing Cracks Can Save Your Building From Long-Term Damage
When cracks and voids are ignored, they often spread deeper into the masonry and accelerate damage. Water intrusion is one of the most common results. Moisture seeps into gaps, freezes in colder seasons, and expands, forcing cracks wider.
Over time, the cycle can break down the bond between masonry units, corrode reinforcement, and compromise load-bearing capacity. Even small separations in structural walls may weaken the system enough to create safety risks, costly failures, or full structural replacements down the line. Early concrete crack repair with epoxy can prevent this.
The Difference Between Epoxy Resin and Polyurethane
Our experts can help you compare epoxy injection resin vs. polyurethane injection, and answer the question, "Why employ epoxy rather than other methods, such as polyurethane?" The truth is that both have their place. Epoxy and polyurethane are both used for masonry crack repair, but the two serve different purposes:
- Epoxy Injection: Best suited for structural reinforcement. The cured epoxy forms a high-strength bond that restores the load-bearing function of cracked or separated concrete and masonry units.
- Polyurethane Injection: More effective for addressing non-structural leaks. It expands within voids to seal out water but does not provide the same structural strength as epoxy.
By understanding the distinction, we at Bramwell-McKay Property Services & Consultants ensure the right approach is used for long-term stability rather than just temporary relief.
Top Signs It’s Time for Epoxy
Injection Repair
Cracks in masonry don’t always announce themselves with sudden failures. Many start small and reveal warning signs long before structural integrity is fully compromised. Below are some of the most common indicators that your structure may benefit from professional epoxy injection.
- Visible cracks across slabs: Large or hairline cracks running through concrete slabs can allow water and contaminants to penetrate, weakening the structure over time.
- Dust and residue around openings: If you notice dust, oil, or grease collecting near cracks or holes, it often points to movement inside the wall that needs to be stabilized.
- Resistance during inspection: When applying gentle pressure with a tool, any unusual resistance or movement may signal deeper fractures that require structural bonding with epoxy.
Unstable materials nearby: Cracks running through areas reinforced with fiberglass or wood can spread faster, especially if not properly coated or sealed. - Changes in crack thickness: A crack that grows thick over time or varies in thickness indicates shifting loads that epoxy can lock back into place.
- Moisture penetration signs: Dampness, staining, or residue on basement walls or vertical surfaces is a clear sign that epoxy is the most suitable option to restore integrity.
- Improper past repairs: Old attempts using caulk or low-quality fillers may have left a hardened layer that failed. Proper epoxy repair involves continuous mixing, careful placement from one cap to the next port, and following manufacturer instructions to ensure the material is tested, meets minimum viscosity, and cures correctly.
If you're a building owner or facility manager, knowing how to look for the problems above can help you address problems early, before they spread into costly repairs.
Our Epoxy Injection Process
Every building and every crack requires a tailored approach. At Bramwell-McKay, we don’t rely on shortcuts. We follow a proven, step-by-step process that addresses both the visible damage and the hidden weaknesses inside the wall.
Beginning with preparation and port installation, and throughout careful resin delivery and final sealing, each stage is designed to restore structural integrity and extend the life of your concrete structures.
Step 1: Surface Preparation
Before any cracks can be treated, our team prepares the area to ensure the material will bond properly. We clean the masonry with a wire brush, remove debris using clean compressed air, and smooth the surface with a putty knife. These steps prevent contamination and help the resin fully adhere to the surrounding concrete structures.
Step 2: Installing
Injection Ports
We place injection ports at carefully measured intervals, making sure the lowest port is set first so material flows upward and fills every void. Once the ports are secure, we apply an epoxy paste to seal the crack’s surface and then paste over the ports themselves. This creates a closed system where the resin can be injected under controlled pressure.
Step 3: Applying
Injection Epoxy
Using specialized injection equipment and a precision injection nozzle, we inject epoxy into the prepared cracks. For wide cracks, additional measures like layering epoxy paste over seams ensure complete penetration. Both vertical applications and horizontal applications can be handled with the same level of accuracy, whether the issue is in load-bearing columns, retaining walls, or basement walls.
Step 4: Final Sealing
and Protection
After the epoxy cures, we remove the ports and smooth the surface. Any exposed metal surfaces are treated for durability, and the area is sealed to block moisture penetration. Depending on the situation, we may also finish with a caulk gun application to provide a clean appearance and added protection.
Get Epoxy Results That Last When You Choose Bramwell-McKay
For over four decades, Bramwell-McKay has combined structural knowledge with hands-on craftsmanship to deliver results that last. Epoxy injection may seem straightforward, but in practice, it requires a deep understanding of how cracks behave within concrete structures and how materials interact under stress.
Our team does what others can’t: we assess each project not just for immediate repair, but for long-term performance. That means choosing the right resin, the right pressure, and the right delivery method—whether in complex vertical applications or sensitive horizontal applications where movement and load differ.
We see every project as stewardship of the building. Restoring structural integrity isn’t just about sealing a crack. For us, it’s about ensuring the entire system remains safe, reliable, and resilient for decades to come.
