Epoxy Injection Grout
Star Leak Proof Epoxy
Solvent-Free Epoxy Injection Grout for Permanent Crack Repair
Star Leak Proof Epoxy Injection Grout is a solvent-free, two-part epoxy system for sealing and repairing cracks in concrete floors, walls, and structural elements. This epoxy injection grout is engineered for contractors, structural engineers, and facility owners who need a permanent fix, not a temporary patch.
Its low-viscosity formula penetrates deep into hairline and structural cracks, bonding tightly to concrete for shrink-free, solid filling. Unlike surface sealants, it restores structural integrity from within, resisting honeycombing and chemical exposure for lasting protection.
How the Features Solve Real Repair Problems
- Low-viscosity penetration — flows into fine and structural cracks that thicker compounds cannot reach
- Solvent-free, two-part formula — combines resin and hardener with zero shrinkage during cure
- High bond and compressive strength — creates a permanent, structural-grade repair, not a cosmetic patch
- Chemical and honeycombing resistance — withstands aggressive industrial exposure without breaking down
- Damp-surface compatibility — bonds effectively even when the concrete substrate isn't fully dry
- Standard equipment compatibility — works with common injection pumps and ports

The Problem
Problems Caused by Untreated Concrete Cracks
Water seepage, structural weakening, and repairs that don't last all start with untreated cracks. Star Leak Proof Epoxy solves all three from within.
Water Seepage & Damage
Cracks allow water penetration, leading to dampness, corrosion, mold growth, and deterioration of concrete structures.
Structural Weakening
Deep cracks can reduce the strength and load-bearing capacity of concrete, creating long-term safety concerns.
Failure of Temporary Repairs
Surface sealants often fail due to structural movement, chemical exposure, and water pressure, causing recurring cracks and leaks.
Benefits
6 Ways Star Leak Proof Epoxy Solves Real Repair Problems
Star Leak Proof Epoxy Injection Grout is a solvent-free, two-component epoxy system designed for permanent crack repair in concrete floors, walls, and structures, penetrating deep into cracks for strong bonding, shrink-free filling, and lasting resistance.
Deep Crack Penetration Stops Water Ingress
Because this epoxy injection grout is low in viscosity, it flows deep into hairline and structural cracks that surface sealants simply can't reach, sealing water pathways right at the source.
Shrink-Free Filling Restores Structural Strength
The solvent-free, two-part formula cures without shrinking, so the grout fills the entire crack volume rather than leaving hidden gaps, restoring load-bearing capacity.
High Bond and Compressive Strength for Long-Term Durability
Star Leak Proof Epoxy Injection Grout bonds tightly to concrete and achieves high compressive strength as it cures, so repaired sections perform like the original structure.
Resistance to Chemicals and Honeycombing Protects Structures
The cured epoxy resists chemical exposure and fills honeycombed concrete completely, protecting structures in industrial plants, water tanks, and chemical storage areas.
Damp-Surface Application Reduces Downtime
Unlike many repair materials, this injectable epoxy grout can be applied to damp concrete surfaces without losing bond strength, so repairs can proceed sooner after cleaning.
Easy Injection with Standard Equipment Speeds Up Repairs
Star Leak Proof Epoxy Injection Grout works with standard injection pumps and ports, so crews don't need specialized tools to complete epoxy crack injection work.
How to Apply
Application Method
Applying Star Leak Proof Epoxy follows three straightforward stages
Surface Preparation
Clean and open the crack, install injection ports along its length, and seal the surface between ports with an epoxy paste band so the injected material stays contained within the crack.
Mixing
Combine the resin and hardener components in the specified ratio and mix thoroughly until the liquid is clear and uniform. Only mix the quantity that can be used within the product's pot life.
Application
Inject the mixed epoxy injection grout through the ports using standard injection equipment at the recommended pressure, working from the lowest point upward on vertical cracks. Allow the repair to cure undisturbed before returning the structure to service.

What Our Customers Say
FAQs
Frequently Asked Questions
Everything you need to know about Star Leak Proof Epoxy.
What is epoxy injection grout used for?
Epoxy injection grout is used to permanently seal and repair cracks in concrete floors, walls, and structural elements. It penetrates deep into the crack, bonds to the concrete, and restores structural strength instead of just covering the surface.
How does epoxy injection grout repair concrete cracks?
Epoxy injection grout is pumped into the crack through injection ports under pressure. The low-viscosity resin fills the entire crack depth, then cures into a shrink-free, solid mass that reconnects the concrete on either side of the crack.
Is Star Leak Proof Epoxy Injection Grout suitable for damp surfaces?
Yes. Star Leak Proof Epoxy Injection Grout is formulated to bond effectively on damp concrete surfaces, which makes it practical for site conditions where materials cannot always be fully dried before repair work begins.
What is the difference between epoxy injection grout and injectable epoxy grout?
Epoxy injection grout and injectable epoxy grout describe the same category of low-viscosity, two-part epoxy systems designed for pressure injection into cracks. Both terms refer to materials engineered for deep penetration and shrink-free crack filling.
How long does epoxy injection crack repair take to cure?
Initial set typically occurs within a few hours, while full cure generally takes about 24 hours under normal site temperatures. Cooler conditions extend curing time, so the repair should be left undisturbed until fully cured.
Can epoxy crack injection be used on load-bearing structural cracks?
Yes. Epoxy crack injection is specifically designed for structural cracks because its high bond and compressive strength restore load-bearing capacity, unlike surface sealants that only address cosmetic cracking.
What is the mixing ratio for Star Leak Proof Epoxy Injection Grout?
Star Leak Proof Epoxy Injection Grout is mixed as a two-part system, combining resin and hardener in the ratio specified on the product packaging. Always mix the entire pack quantity to maintain the correct chemical balance.
Is epoxy injection grout resistant to chemicals and water?
Yes. Once cured, epoxy injection grout resists chemical exposure and has virtually nil water permeability, making it suitable for tanks, treatment plants, and other environments with frequent chemical or moisture contact.
What equipment is needed for epoxy injection crack repair?
Epoxy injection crack repair requires standard injection pumps or hand-operated injection guns, injection ports or packers, and basic surface preparation tools such as grinders or wire brushes. No specialized machinery is required.
How much epoxy injection grout do I need for a project?
The amount required depends on the length, width, and depth of the cracks being repaired. Measuring total crack volume before ordering helps avoid running short of material mid-injection, since mixed batches must be used within their pot life.
