Carbonbond Structural Systems

Carbonbond Carbon Fiber
Carbonbond is a bi-directional carbon fiber fabric used to strengthen structural elements and laminated using Intech Anchoring Epoxy Resin #400.
The Carbonbond System is an ideal choice for foundation damage of two inches or less in width because they provide maximum stability repair without requiring invasive drilling or excavation in a basement. Woven fiber comes in uni-directional and bi-directional options, allowing for the resistance of movement in one direction or two directions, respectively. The type of carbon fiber for your repair will be dependent upon the severity and characteristic of the offending crack.
An added steel angle at the top of the wall effectively concludes the repair. The finished product can easily be painted over to blend in with the space and contribute to a clean, comfortable living area. This fix is permanent, as carbon fiber repairs require zero maintenance.

BI-DIRECTIONAL CARBON FIBER
- No excavating or drilling as the Carbonbond System installs easily without the need for heavy or noisy equipment.
- Compared to steel, Carbon Fiber is over 10 times stronger, much thinner (only one-tenth of an inch), and 40 times lighter.
- Carbonbond repairs are completely maintenance-free because they never will corrode like steel.
- With the ease of installation, its incredible strength, and the durability of Carbon Fiber, it’s easy to see that no other choice makes sense.

Directions for Use
Surface Preparation
Mixing Epoxy
It is crucial that the epoxy is mixed thoroughly and completely, which is why a mixer is recommended.
WARNING: Epoxies develop heat during mixing and curing. To keep temperature rise to a minimum, a high surface area to volume ratio during mixing is recommended. For manual mixing, each mix volume should be kept to 5 gallons or less. For automated mixing follow the equipment manufacturer’s instructions.
First, mix each component separately. Proportion each component at their specified ratios and mix using a slow-speed drill with jiffy paddle at 400-600 RPM for 3-5 minutes until a consistent color is achieved. No stripes, streaks, or color variation should be visible. Use an up and down motion, scraping the mixing container sides and bottom. Mix no more material than may be applied within the specified pot life of the epoxy.
Dry Lay-Up
- Using a roller or sprayer, apply a coat of Intech Anchoring primer onto the prepared surface.
- Apply a coat of saturating resin (Intech Anchoring#400) to the still tacky primed surface.
- Press the dry fabric (wrap) onto the surface and using a roller, apply pressure to the surface of the fabric to ensure good bonding to the substrate and to roll out any entrapped air before the epoxy sets. Smooth the fabric from the center to the edge to remove air pockets. Good saturation of the fabric is indicated by some epoxy oozing out to the external face of the fabric and wetting the fibers on the external face.
- Apply a final coat of saturating resin on top of the fabric using a roller or by using a sprayer (spiked roller can be used to remove any entrapped air).
- Apply paint or protective coating if desired while the final resin coat is still tacky. The fully cured resin must be scuffed for optimum bonding to the paint or protective coating When multi-layer wraps are used, each individual layer shall be firmly bedded and adhered to the preceding layer or the substrate before the epoxy on the preceding layer is fully cured and is still tacky.
Wet Lay-Up
- Using a roller or sprayer, apply a coat of Intech Anchoring primer onto the prepared surface.
- (For applications requiring Tack Coat): Apply the tack coat (Intech Anchoring#4) to the surface using a trowel or putty knife, filling out all pores and leaving a 20-mil thick coating (measured wet) of the tack coat on the surface.
- Press the resin-saturated fabric onto the substrate and using a roller applies pressure to the surface of the fabric to ensure good bonding to the substrate and to roll out any trapped air before the epoxy sets. Smooth the fabric from the center to the edge to remove air pockets.
- Apply paint or protective coating, if desired while the final resin coat is still tacky. The dry resin must be scuffed for optimum bonding to the paints or protective coatings.

Conditions to Avoid
- Do not apply to concrete with temperature outside of application temperature range
- Do not apply to concrete less than 30 days old
- Do not apply to concrete with curing or sealing membranes
- Do not apply to base concrete at a temperature less than 45°F
Benefits of Carbonbond
Installation can be accomplished with a team of 1-3 members and only relies on a few simple tools. First, the crack is injected with either epoxy or urethane, depending upon the condition of the fracture, then concealed with carbon fiber strips, which reinforce the wall and prevent further damage. With no welding, digging, or excavating required, the set-up, installation, and cleanup processes are minimally disruptive to the home.
