Crack Injection: Sustainable LEAK REPAIR Solutions for Concrete
Water infiltration is one of the biggest threats to concrete infrastructure.
Cracks, joints and voids in tunnels, parking garages, seawalls, and dams for example, allow moisture to penetrate, accelerating corrosion, structural deterioration, and maintenance costs.
Polyurethane crack injection resins offer a precise, long-term, and sustainable solution for waterproofing concrete structures across diverse climates.
How Polyurethane Crack Injection Works:
Polyurethane resins, such as those in the Prime Flex series, are low-viscosity, water-reactive systems.
Injected into cracks and joints, they expand on contact with water to form flexible or rigid watertight seals.
Key types include:
Hydrophilic flexible gels: Expand in hairline cracks and moving joints, creating a flexible seal.
Hydrophobic rigid foams: Form durable barriers for high-pressure leaks and void filling.
Dual-behavior resins: Cure as gel or foam depending on water exposure, adapting to varied applications.
These systems stop leaks at the source, preserving structural integrity and minimizing material waste.
Climate-Adapted Performance:
Prime Resins’ polyurethane crack injection systems are engineered to perform under diverse environmental conditions:
Cold climates: Flexible gels accommodate freeze-thaw cycles and cure reliably at low temperatures.
Marine/tropical climates: Saltwater-resistant foams withstand humidity, corrosion, and UV exposure.
High hydrostatic zones: High-expansion resins seal leaks under water pressure and adapt to seasonal water changes.
This ensures long-term waterproofing in Canada, South America, and the Caribbean.
Sustainability Benefits:
Targeted injection: Minimizes material waste.
Durable performance: Permanent seals reduce repeated repairs.
Low VOC formulations: Safe for potable water and low-emission environments.
Applications Ideal for:
Subterranean structures: Tunnels, parking garages, sewers
Coastal/marine structures: Seawalls, retaining walls
Foundations, basements, and critical infrastructure: dams, airports, bridges
Anywhere water threatens concrete, polyurethane crack injection resins stop leaks from the inside out, providing a long-lasting, watertight solution.
Key Takeaways for Engineers, Project Managers:
Select resin type based on crack width, leak severity, and environmental conditions.
Review technical specifications: expansion ratio, viscosity, cure time, and adhesion.
Ensure monitored installation for verified long-term performance.
Polyurethane crack injection resins offer technically advanced, sustainable, and climate-adapted waterproofing for concrete infrastructure.
