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.

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.
