Over time, concrete structures can develop cracks due to settlement, shrinkage, or exposure to moisture. These cracks not only weaken the structure but also allow water to seep in, causing further damage.
At Markone Contractors, we specialize in concrete crack injection and leak sealing — a proven method to restore structural integrity and prevent water infiltration in foundations, basements, parking garages, retaining walls, tunnels, and more. Our expert technicians use epoxy or polyurethane injection systems depending on the nature of the crack, ensuring durable and long-lasting results.
Our team begins by inspecting the cracked area to identify the type, width, and cause of the crack. We then determine whether it’s a structural or non-structural issue to select the appropriate injection method.
The surface is cleaned and prepared by sealing the crack on the surface and installing injection ports at intervals. This ensures that the injected material can penetrate deep into the crack.
We use high-pressure injection pumps to deliver epoxy (for structural repairs) or polyurethane foam (for water leak sealing) into the crack. This process fills even the smallest voids, bonding the concrete back together or expanding to seal water pathways.
Once the injection material cures, we remove the ports, smoothen the surface, and perform a final inspection to verify the success of the repair and ensure that the area is completely sealed and structurally sound.
Ideal for repairing foundation cracks and basement leaks, preventing water ingress that leads to mold and structural decay.
Used to restore load-bearing capacity and seal cracks caused by stress, heavy loads, or weather exposure.
Provides leak-proofing for underground structures and water-retaining systems, ensuring safety and durability.
Our process begins with a detailed on-site assessment to identify the cause, size, and severity of the crack or leak. Based on our findings, we select the most suitable epoxy or polyurethane system to ensure a durable and effective repair.
Using advanced injection equipment and proven techniques, our trained professionals carefully inject the selected material deep into the crack. This ensures full penetration, structural bonding, and complete waterproof sealing — restoring the strength and integrity of the concrete.
Once the injection process is complete, we smooth and finish the surface for a clean appearance. A thorough final inspection follows to confirm that the repair is fully sealed, structurally sound, and ready to withstand long-term use.
Concrete crack injection is a repair method where epoxy or polyurethane resin is injected into cracks in concrete to restore structural strength or seal leaks. It’s a non-invasive and highly effective way to fix cracks without removing or replacing the concrete.
Epoxy injection is used for structural repairs, bonding the concrete back together and restoring its original strength.
Polyurethane injection (PU) is used for waterproofing, as it expands to seal active leaks and prevent future water infiltration.
Most projects can be completed in a few hours to one day, depending on the size and number of cracks. Larger or more complex structures may require additional time for curing and quality inspection.
When done professionally using industrial-grade materials, the repair can last 20+ years or even the lifetime of the structure, provided the underlying cause of cracking (like settlement or stress) is addressed.
Concrete injection is suitable for foundations, basements, retaining walls, parking garages, tunnels, water tanks, and any concrete structure showing cracks or water intrusion.
