Quick Detail

1. Different names:

Epoxy Resin Grouting/ Epoxy/ Epoxy Grouting Resin

2. Main uses:

RUTH Epoxy Resin is a low-viscosity structural adhesive designed for concrete crack repair. High-strength bonding for bridges, foundations, and beams. Factory direct bulk supply.

3. Extreme Performance:Compressive Strength with 110MPa
(much higher than market average level of 40MPa)

Description

RUTH Epoxy Resin Grouting is a high-strength, two-component, solvent-free epoxy crack filler designed to restore the structural integrity of cracked concrete. Unlike polyurethane foams that are flexible and used for stopping water, this structural epoxy injection material cures into a rigid solid that is stronger than the concrete itself.

Formulated with low viscosity, our liquid epoxy grout penetrates deep into hairline cracks (as narrow as 0.05mm), effectively "welding" the concrete back together. It is the industry standard solution for concrete crack repair epoxy injection in load-bearing structures.

Primary Applications

RUTH Epoxy Resin is engineered for structural crack repair where strength is paramount:

Infrastructure Repair: Repairing cracks in bridges, dams, pillars, and beams (epoxy injections for structural cracks).
Foundation Repair: Sealing stress cracks in epoxy injection foundation crack repair projects to prevent future shifting.
Industrial Flooring: Filling delamination and static cracks in warehouse floors.
Precast Concrete: Repairing transport damage in concrete segments.
Earthquake Damage: Post-seismic structural retrofitting.

Key Features & Benefits

Structural Restoration: Provides high tensile and compressive strength, effectively restoring the monolithic nature of the structure (epoxy injection for structural bonding).
Ultra-Low Viscosity: Flows easily into micro-cracks under low pressure, ensuring complete penetration without surface capping failure.
Moisture Insensitive: Excellent adhesion even on damp concrete surfaces (though not designed for flowing water).
Zero Shrinkage: 100% solids content ensures the material does not shrink during cure, maintaining a permanent bond.
Chemical Resistance: Resistant to oils, salts, and mild acids, protecting the rebar from corrosion.

Why Choose RUTH Epoxy?

Manufacturer Direct: We produce high-grade epoxy grouting material in our Shanghai facility, offering significant cost savings for Specialist Subcontractors and distributors.
Complete Injection System: For best results, use RUTH Epoxy Resin with our surface-mounted or drilled epoxy injection packers and low-pressure injection pumps.
Bulk Availability: Available in various packaging options (cartridges for small jobs or drums for epoxy injection crack repair cost efficiency on large projects).

Comparison: Epoxy vs. Polyurethane

Q: Should I use Epoxy or Polyurethane for my crack?

A:Choose RUTH Epoxy if the crack is "Static" (not moving) and you need to restore the structural strength of the concrete (e.g., a cracked load-bearing beam or column).

Choose RUTH Polyurethane if the crack is "Active" (leaking water) or "Dynamic" (moving). Epoxy will crack if the structure moves, whereas PU foam is flexible. (Need to stop a leak? Visit our [ruth-hydrophilic-polyurethane-grout] page.)

Packaging & Storage

Reinforcement Construction Methods

High-pressure Injection

1. Deploy epoxy resin (Component A) and curing agent (Component B) at a mixing ratio of A:B = 100:20 (by weight).

2. Inject the mixed epoxy into the structure's cracks with a RUTH high-pressure injection machine. To ensure the complete filling of the cracks, the injection should be repeated within 30 minutes until the epoxy material begins to seep from the cracks.

3. After 72 hours, clean up the solidified material, pull out the injection packers, and seal the injection holes with a waterproof polymer mortar.

Notes

1. During application, please wear protective apparatus (e.g., gloves, goggles) to avoid direct contact with the skin. If contact occurs, please flush the affected area with running water. If it comes into contact with the eyes, seek immediate medical care at a hospital.

2. The epoxy resin (A) and curing agent (B) must be mixed evenly according to the specified mixing ratio.

3. The mixture of epoxy A and B should be used within its pot life (workable time). Otherwise, it will solidify and become unusable.

4. Spatulas, mixers, and containers should be washed with acetone after use, before the epoxy hardens.
