Epoxy Injection
Pressure-inject low-viscosity epoxy into dormant cracks to restore structural bond and seal against moisture and chloride intrusion.
Pressure-injecting low-viscosity epoxy resin (typically 50–200 psi) into dormant cracks 0.002"–0.5" wide restores structural bond across the crack and seals it against moisture and chloride intrusion — essentially "welding" the crack back together.
At Costal Concrete, epoxy injection is used on parking garages, high-rises, bridges, and industrial floors where non-moving structural cracks show no active corrosion. Work follows ACI 224.1R, ACI 503.7, ASTM C881, and ICRI 210.1R guidance for Florida commercial structures.
Our crews begin with crack assessment, cleaning, and port installation, then inject resin in a controlled sequence so the material fills the full crack depth. Surface ports are removed and the face finished so the repair blends with the surrounding concrete.
When specified correctly, epoxy injection returns load path continuity, slows chloride ingress, and helps owners avoid premature full-member replacement — a cost-effective first line of defense for dormant structural cracking in coastal Florida.
Key benefits
Triggered by
Non-moving structural cracks with no active corrosion that need bond restoration and moisture sealing.
