Concrete
Crack Lock®

Carbon Fiber Crack Stitching System

The professional-grade solution for structural concrete crack repair. Engineered for contractors and engineers who demand faster installs, lower labour costs, and structural performance. 195,000 PSI tensile strength per stitch that outlasts rebar and epoxy-only methods.

Stronger Than Steel
Rapid Install — Less Downtime
Non-Corrosive
Residential & Commercial Grade
Built for Professionals
Who Can't Afford Failure

The Concrete Crack Lock® gives contractors and structural engineers a faster, stronger, and more cost-effective alternative to traditional rebar stitching and epoxy-only systems.

01
Structural Integrity
Takes full advantage of carbon fiber's tensile strength, transferring stress to undisturbed concrete zones rather than relying on epoxy alone.
02
Less Concrete Removal, Less Epoxy
Engineered profile requires minimal substrate removal. Uses significantly less epoxy than conventional methods, reducing material costs on every job.
03
Dramatically Lower Labour Costs
Install in a fraction of the time of rebar stitching. Fewer cuts, fewer fills, faster cure. Your crew moves faster. You bid more competitively and protect margins.
04
Smooth Finish, Paintable Surface
Minimal aesthetic footprint. Paint, coat, tile, or polish over it.
05
Non-Corrosive
Carbon fiber never rusts. Eliminates the cracking and delamination cycle caused by corroding steel in wet and marine environments.
Engineered for
Every Job Site

Hundreds of residential and commercial applications from foundations to infrastructure. If there's a concrete crack, there's a Crack Lock® solution.

Eight Steps. One Saw Cut. Done.

Crack Lock® is designed for field crews. The install is fast, repeatable, and requires no specialty equipment beyond what's already on your truck.

01

Prep

Grind across the surface of a crack to ensure its level.

02

Locations

Install first CCL as close to the start of the crack as possible. CCL's should be installed every 8" to 12". Center the CCL to the crack and trace the outline. Vary angles slightly to reinforce the crack.

03

Drill

Drill 1/2" holes at each end of the cut where the lock will be inserted.

04

Cut

Make the cut across the crack for the CCL, ensuring the cut is full depth from hole location to hole location.

05

Clean

Vacuum or blow out all debris. Dust-free channels are critical for full epoxy adhesion and maximum pull strength.

06

Epoxy

Inject RHINO High-Strength Anchoring Epoxy Paste along the full length of the cut using the supplied mixing nozzle.

07

Install

Press the Crack Lock® stitch firmly into the epoxy-filled slot. The pre-preg fiber bonds immediately into the matrix. Top off the cut with Epoxy until it is even with your concrete.

08

Finish

Smooth the surface, patch the remaining crack, then paint, coat, tile, or leave raw.

SPACING: Standard spec is 6"–12" on-center depending on crack type and load.   STRUCTURAL LOADS: Consult a licensed engineer for live-load or seismic applications.
