SRS-3000 Crack Injection Epoxy – High-Strength, Low-Viscosity Structural Injection Resin
The SRS-3000 Crack Injection Epoxy is a professional-grade, two-component resin designed for the structural repair of cracks in concrete, masonry, and foundation walls. Formulated with low viscosity and high tensile bond strength, SRS-3000 penetrates deeply into hairline cracks, restoring the original monolithic strength of damaged concrete.
Engineered for contractors, engineers, and structural repair professionals, SRS-3000 is ideal for load-bearing structural cracks, foundation settling, basement leaks, and pre-FRP substrate preparation.

Specification
The repair epoxy shall be a two-component, 2:1 mix-ratio structural injection resin supplied in pre-measured cartridges. When cured for 7 days at a minimum temperature of 60°F (16°C), the epoxy shall achieve:
-
Minimum compressive yield strength of 10,150 psi (70.0 MPa) per ASTM D695
-
Tensile strength suitable for structural crack injection applications
-
Bond performance compatible with FRP strengthening, structural repair mortars, and substrate preparation
The specified product shall be SRS-3000 Crack Injection Epoxy manufactured by Structural Reinforcement Solutions, Thornville, Ohio.
Applications
SRS-3000 is designed for structural and non-structural crack repair in:
-
Load-bearing concrete cracks
-
Slab-on-grade cracks
-
Masonry cracks
-
Cracks caused by settlement, shrinkage, or flexural stress
-
Water-infiltration and leak repair when paired with polyurethane foam injection
-
Pre-FRP strengthening substrate preparation
-
Anchoring of ports and injection fittings
-
Void filling and micro-crack consolidation in concrete and masonry
This epoxy can be applied in horizontal, vertical, and overhead configurations.
Features & Benefits
SRS-3000 is engineered for deep penetration into fine cracks, long-term load transfer, and high-performance structural bonding. Its low viscosity allows the resin to chase fine fractures that traditional epoxies cannot reach, ensuring full monolithic restoration.
Low Viscosity
Ideal for pressure injection or self- leveling applications for structural repair of concrete cracks ranging from 1/8 inch to less than 1/4 inch.
NTPEP Approved
Evaluated and approved by the National Transportation Product Evaluation Program.
USDA Acceptance
Suitable for use in USDA inspected facilities.
Moisture Insensitive
Effective performance in wet conditions.
Versatile Usage
Acts as an epoxy resin binder for mortar repair, patching, and overlaying interior surfaces including aggregates.
Sealer Capabilities
Effective as a sealer for interior slabs and exterior above-ground slabs, decks, patios, driveways, parking garages, and other structures.
Shear Fracture Repairs
Suitable for repairing shear fractures on both interior and exterior concrete slabs.
Industrial Primer
Can be used as a primer for industrial coatings.
Surface Sealant
Applicable as a surface sealant for various surfaces.

Frequently Asked Questions
Can SRS-3000 be used on actively leaking cracks?
For actively leaking cracks, stop water infiltration first using a polyurethane foam injection. Once the area is dry, use SRS-3000 for structural reinforcement.
How deep does SRS-3000 penetrate?
The low-viscosity resin penetrates tightly into hairline cracks down to 0.002" depending on moisture content and injection pressure.
Is SRS-3000 compatible with FRP systems?
Yes. The resin is commonly used as a substrate repair material prior to installing carbon fiber strengthening systems like SRS-600UNI or SRS-660BI.
Can I use SRS-3000 in cold temperatures?
For best performance, ambient and surface temperatures should remain above 60°F. Below this, cure time increases.
