Epoxy Crack Injection: Concrete Repair Solutions for Foundations & Basements
Foundation and basement cracks can range from cosmetic nuisances to active leak paths to early warnings of real structural movement, and matching the right injection material to the right crack type is what separates a lasting repair from a callback waiting to happen. Intech Anchoring Systems supplies epoxy crack injection materials and concrete repair solutions for foundations and basements that foundation repair contractors, waterproofing specialists, and concrete restoration crews depend on for both structural and water-infiltration repairs.

Two Resin Systems for Two Different Crack Problems
Concrete cracks fall into two basic camps that need fundamentally different treatment. Structural cracks, where the wall has lost monolithic strength and needs the bond restored, call for epoxy. Cracks that are passing water but not actively moving call for polyurethane, which expands and reacts with moisture to fill voids and shut down the leak path. Mixing those approaches wastes material and produces failed repairs, which is why our team helps contractors specify the right system before injection begins rather than after.
Both resin families share useful properties: moisture-insensitive cure for damp or wet substrates, simple mix ratios that crews can manage on site, no shrinkage during cure, and strong adhesion to concrete, wood, and metals.
Concrete Crack Situations Injection Solves
Epoxy and polyurethane injection address a wide range of concrete repair situations across residential and commercial construction. The list below covers the application types our customers regularly deliver to their own clients.
- Poured concrete foundation cracks: Vertical and diagonal cracks in poured walls where epoxy restores monolithic strength and seals against water entry.
- Basement wall water leaks: Active or seasonal leaks through hairline cracks where polyurethane expands to chase moisture and fill the leak path completely.
- Cold joint and form-tie hole sealing: Construction joints and through-wall penetrations that allow water entry, sealed with polyurethane to maintain dry interiors.
- Slab and floor crack repair: Horizontal cracks in slabs, basement floors, and parking decks where epoxy or polyurethane addresses both structural and infiltration concerns.
- Retaining wall crack repair: Cracks in poured concrete retaining walls exposed to soil hydrostatic pressure on the back side.
- Concrete ceiling and overhead deck cracks: Cracks in suspended slabs and overhead concrete elements requiring upward injection and specialty port techniques.
- Void filling behind anchor plates: Polyurethane rigid foam expanding to fill voids behind tieback plates, helical wall anchors, and deadman anchors in water-bearing soils.
- Sub-slab and exterior foundation void fills: Filling voids under settled slabs and outside foundation walls where soil has eroded or migrated.
Epoxy Crack Paste Stays Stuck
Epoxy crack paste stands out as a superior solution for resolving cracks in concrete or masonry walls, delivering unmatched durability and adhesion. This advanced material is specially formulated to penetrate deeply into the cracks, providing a robust and long-lasting bond that effectively seals the damaged area.
Intech Anchoring Systems’s epoxy crack paste is easy to apply, making it a convenient choice for contractors. Its quick curing time means that repairs can be completed efficiently, minimizing disruption and allowing for faster project completion. Whether you’re dealing with minor cracks or significant structural issues, our line of crack repair products provides a reliable and effective solution that stands the test of time.
Sealing Cracks From Moisture
Moisture infiltration is a common issue in foundation and basement walls. Cracks in the concrete can allow water to seep in, leading to potential damage and structural problems.
Our polyurethane or grout injection systems effectively seal the cracks, creating a barrier that prevents moisture from entering the structure. By sealing the cracks, we help protect against water damage, mold growth, and other moisture-related issues, ensuring a dry and safe environment.
Durable And Reliable Void Filler
Polyurethane rigid foam is a superior material for structural repairs, especially in water-bearing soils. It expands upon application to fill voids behind tie-back plates, helical wall anchors, deadman anchors, under slabs, and outside foundation walls.
The foam’s rigid nature provides a stable bond that withstands pressure and movement, making it ideal for reinforcing critical areas in foundations and other structures. Easy to apply and quick to cure, polyurethane rigid foam from Intech Anchoring Systems guarantees reliable and efficient repairs, protecting the structures’ integrity for the long term.
Providing Added Support To Damaged Concrete
Cracks in foundation and basement walls can weaken the overall structure, compromising its stability. Our epoxy and urethane injection systems go beyond just sealing the cracks; they provide a comprehensive solution that ensures long-term protection and peace of mind. By using advanced materials that penetrate deeply and bond firmly within the cracks, our systems prevent water infiltration and future damage.
Benefits Of Expoxy & Urethane Injection
- Cures reliably even on damp or moisture-prone surfaces
- Simple mixing process for easier application
- Formulated to resist shrinking after curing
- Strong bonding performance on concrete, wood, and metal surfaces
- Penetrates deeply into structural cracks for durable concrete repair
Applications Of Expoxy & Urethane Injection
- Basement & foundation cracks
- Retaining walls
- Concrete ceilings & decks
Installation Of Epoxy & Urethane Injections
Both the installation of Epoxy and Urethane injection systems is swift, often requiring only a single crew member, and causes minimal disruption. This means that the setup, installation, and cleanup processes are quick and hassle-free. In addition to the injection system itself, the necessary tools include a concrete drill, basic hand tools, and materials for surface cleaning and preparation.
When using Intech Anchoring Systems’s concrete repair injection supplies, the process becomes even simpler. It involves mixing the two components, placing injection ports at regular intervals of 6-12 inches, and injecting the repair resin into the crack. Once all the ports are filled, the resin is left to fully cure, which typically takes an average of seven days after completion.
Intech Anchoring Systems provides all the essential accessories for crack repair, including high-quality injection guns, injection ports, and static mixers. Our durable injection guns ensure precise application, while the reliable injection ports and static mixers facilitate accurate delivery and consistent mixing of repair materials. With our comprehensive range of tools, contractors can achieve efficient and effective crack repairs.

Frequently Asked Questions
When should I specify epoxy injection vs polyurethane injection?
Epoxy is the right call for structural cracks where you need to restore the wall’s monolithic strength and the crack is no longer moving. Polyurethane is the right call for active or seasonal water leaks, where the resin’s expansion and moisture reactivity matter more than rigid bonding. Some projects use both in sequence on different cracks within the same wall.
How long does an epoxy crack injection take to cure?
Initial set typically happens within hours, but full cure to design strength generally takes about seven days. Polyurethane reacts and expands much faster, often setting up within minutes once it contacts moisture in the crack.
Can crack injection be performed on damp or actively leaking surfaces?
Yes. Both our epoxy and polyurethane resins are formulated to cure on damp or wet substrates, which is part of why they work well for foundation and basement applications where dry conditions are rarely guaranteed. Polyurethane in particular benefits from moisture presence to drive its reaction.
When is crack injection not enough?
Injection seals the crack and restores material continuity, but it doesn’t address the underlying cause of structural movement. If the foundation is settling, the wall is bowing inward from soil pressure, or cracks are recurring after repair, structural reinforcement with wall anchors, resistance piers, or helical underpinning is the right path forward.
Does Intech provide installation training for crack injection crews?
Yes. Our technical staff supports contractors getting started with injection work, including resin selection guidance, port placement coaching, and troubleshooting support for crews moving from carbon fiber or other repair methods into chemical injection.
Why Foundation Repair and Waterproofing Contractors Choose Intech
Crack injection is a craft trade as much as it is a chemistry decision, and the contractors who do it well have learned that resin selection, dispensing pressure, port spacing, and substrate prep all have to land right for the repair to last. We also believe in honest scope guidance. When a crack inspection points to settlement, lateral wall movement, or a structural problem that injection won’t fix, our team says so and points contractors toward the foundation repair products that actually solve the underlying issue.
