Polyurethane Crack Injection Services
Expert Solutions to Strengthen Structures and Improve SafetyEpoxy Design Systems delivers polyurethane crack injection services explicitly for wet and water-compromised environments. We utilize engineered materials to stop active leaks, restore structural integrity, and extend the service life of structures. This can be accomplished with limited or no downtime to the operating structure.
Our Polyurethane Injection Process
We deliver polyurethane crack injection services designed to seal active leaks in water-damaged concrete. Our innovative process ensures long-lasting performance in critical commercial and industrial environments.
The information below details what it may look like for you and your project.
- Site Assessment: Every polyurethane injection crack injection project begins with a detailed inspection of the affected concrete. Technicians must evaluate the location, width, and depth of visible cracks, noting any signs of water intrusion, rust staining, or efflorescence.
- Injection Plan: Once we’ve completed the data collection, our team develops a site-specific plan for crack injection/sealing.
Applications for Polyurethane Injection
We utilize our polyurethane crack injection services in critical infrastructure settings where moisture intrusion threatens structural integrity.
Our technicians apply polyurethane injection for concrete cracks in a wide range of high-moisture environments, including the following:
- Basements
- Below-grade structures
- Containment sumps
- Culverts
- Manholes
- Sewer plants
- Underground pipes
- Elevator pits
- Aeration and waste water basin
- Cooling tower basins
Polyurethane injection for foundation repair is commonly utilized to stop water infiltration through cold joints, cracks in concrete structures, failed expansion joints, and damaged water stops.
Benefits of Polyurethane Injection
Because the foam from polyurethane injection expands upon contact with water, it creates a flexible, water-tight seal without needing dry conditions. This makes it ideal for sealing below-grade structures that managers cannot take offline for extended periods. Instead, our team can complete repairs with minimal disruption to operations.
A considerable advantage of implementing these injection processes is that the material adapts to irregular voids, helping to penetrate fine cracks while curing rapidly. Unlike rigid alternatives, polyurethane crack injection services provide an effective seal even as structures shift or settle slightly over time.
Epoxy vs. Polyurethane Crack Repair
The choice between epoxy and polyurethane depends on site conditions and the stability of the crack or joint. Epoxy injection is used for structural crack repair where concrete must regain strength and stability and expansion and contraction is not a deciding factor. Epoxy bonds tenaciously to dry surfaces and restores load-bearing capacity; however, it is not really suitable for wet environments.
In contrast, polyurethane injections for concrete cracks are formulated for active leaks and high-moisture conditions. This makes it the preferred choice for non-structural waterproofing and foundation repair in water-compromised areas.

Polyurethane Crack Injection FAQs
Polyurethane crack injection is a repair method that pumps a liquid polyurethane resin into cracks and joints in concrete. When the resin contacts water, it reacts and expands into a flexible foam that fills the crack and forms a watertight seal. Epoxy Design Systems uses this method to stop active leaks in below-grade and high-moisture structures across commercial and industrial facilities.
Yes. Polyurethane resin is designed to work in wet conditions, so the crack does not need to be dried out before the repair. The resin reacts with the water already present, expands to fill the void, and seals off the leak path. This makes it a strong option for basements, manholes, culverts, elevator pits, and other structures where water is moving through the concrete.
No. Polyurethane injection is a waterproofing repair. It seals cracks and joints against water but does not restore the structural strength of the concrete. If a crack affects load-bearing capacity, epoxy injection or carbon fiber reinforced polymers (CFRP) may be the better solution.
Yes, for foundation leaks. Polyurethane injection is commonly used to stop water infiltration through foundation cracks, cold joints, failed expansion joints, and damaged water stops. Crack injection seals the leak but does not correct settlement or restore structural capacity. If a foundation crack is caused by structural movement, the cause should be assessed before the crack is sealed.
Usually not. Because polyurethane cures in wet conditions, repairs can often be completed while the structure stays in service. This is a major advantage for wastewater basins, cooling tower basins, containment sumps, and other below-grade structures that cannot be taken offline for long. Our crews plan each project to keep disruption to daily operations as low as possible.
Cost depends on the total length and width of the cracks, how much water is coming through, access to the repair area, and site conditions such as confined spaces or operating equipment. Because every structure is different, Epoxy Design Systems prices projects after a site assessment. Request a quote to have our team review your project.
Both use polyurethane, but they solve different problems. Crack injection uses a low-viscosity resin that fills cracks and joints to stop water. Concrete lifting uses a high-density foam injected beneath a slab to raise it and fill voids in the soil below. For voids and soil stabilization around structures, see our PUR chemical grouting and pressure grouting services.
