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.

02

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.

03

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.

04

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.

01

When is epoxy injection the right repair?

When cracks are dormant (not actively moving) and there is no ongoing corrosion that would reopen the repair.

02

How wide of a crack can epoxy injection treat?

Typically cracks from about 0.002" to 0.5" wide, using low-viscosity resins injected under controlled pressure.

03

How long does an epoxy injection repair last?

Properly injected epoxy creates a permanent structural bond. Longevity depends on stopping the original cause of cracking and keeping chlorides and moisture under control.

04

Will the repair be visible on the finished surface?

Injection ports leave minor surface marks that we grind and finish. Most clients see a clean, serviceable appearance after completion.
