NextStar Carbon Fiber Concrete Stitch Kit 

15 Pre-Tensioned Carbon Fiber Concrete stitches and Epoxy kit 
Carbon Fiber Stitch Kit: Repair Cracks 10x Stronger Than Steel


The NextStar Concrete Stitch features high-tensile strength carbon fibers that are pre-tensioned during manufacturing. This makes it ideal for concrete wall crack reinforcement repair, providing the least movement and the highest tensile support. They are typically used for concrete crack repair and reinforcement, as well as for concrete floors, foundation walls, swimming pools, and any other poured concrete that requires reinforcement. Typically installed 12-24 inches apart, this stitch is stronger than traditional concrete staples and is easy to install. This structural crack stitching and reinforcement system is a pre-impregnated, unidirectional, pre-tensioned carbon fiber stitch for structural reinforcement for crack stitching. It is typically used in conjunction with epoxy injection or other structural crack injection methods. The concrete stitch has more than twice the surface area of staples, which helps it create a stronger and more effective bond.

  • Carbon fiber grid for floors and walls 15 Carbon Fiber pre-tensioned Stitches
  • StarTech anchor Epoxy 1  Set 450mls of Carbon Fiber Epoxy A+B
  • 4.5 Inch Diamond Concrete Cutting Blade 1 4.5 Inch Diamond Turbo Blade

Product Basics


Q. What are carbon fiber concrete stitches, and how do they work?
A. NextStar Carbon Fiber Stitches are high-strength reinforcement staples used to repair and stabilize cracked concrete permanently. They work by spanning cracks like stitches in fabric—the pre-tensioned carbon fiber staples (10x stronger than steel) are embedded into slots cut across the crack, then bonded with industrial epoxy. This creates a "bridge" that:
1. Distributes structural loads away from the crack
2. Prevents further widening (unlike surface-level patches)
3. Resists movement from freeze/thaw cycles or settling
Unlike steel staples, they won’t rust and have a 44 sq.cm bonding area for maximum hold. Ideal for foundations, pool decks, and load-bearing walls.

Installation


Q. How do I install these stitches? Is professional help needed?
A. The process is very simple; all that is needed is to cut a ¾ to 1inch slot 12 inches long, vacuum or blow out the dust. Then insert with the epoxy provided.

Q. What tools are required beyond what’s in the kit?
A. A 4.5-inch hand grinder and vacuum or compressed air to remove dust from the slot.

Performance & Durability


Q. How strong are these stitches compared to steel or those of our competitors?
A. Nextstar stitches have a 2,884 MPa strength, but more importantly, have double the surface area of bonding. This is important because any carbon is unlikely to fail before the concrete does; thus, a larger concrete area is needed to achieve the full performance of the Stitch compared to competitors.

Q. Will they rust or corrode over time?
A. No Nextstar Carbon fiber stitches do not corrode or age, unlike steel products. Most steel products are installed with cement products and start to corrode right after installation.

Applications


Q. What types of cracks/concrete structures can they repair
A. Nextstar Carbon Fiber Stitches can be used on poured concrete foundation walls, vault, floors and deck crack repairs, including pool repairs or reinforcing.

Q. Can they be used on vertical surfaces like walls?
A. Yes the stitches can be applied in any wall, floor, or ceiling combination.

Q. How far apart are the stitches installed?
A. The typical installation spacing is 9 to 18 inches apart, depending on the amount of reinforcement required.

Warranty & Support


Q. What does the 10-year warranty cover?
A. The warranty covers the stitch itself against breaking under tensile load, provided it has been installed according to the instructions. It does not cover the concrete or the installation of any replacement.

Q. What if my repair fails? Who do I contact?
A. In the unlikely occurrence of any failure, contact our technical support team by contact form or phone 866-445-3984 ext 3

Comparisons


Q. How do these compare to Fortress/Rhino stitches?* (Bonding area, DIY ease, warranty)
A. The key difference is that the Nextstar Stitches are pre-tensioned, so they have the least stretch before holding any load. This keeps the crack repair from re-cracking.

Nextstar stitches have the largest bonding surface area, which means they can hold more than the competition.
Q. Why choose carbon fiber over steel staples or epoxy injections?
A. Carbon fiber has more resilience to environmental changes. Stitches are usually used with Epoxy Injections , epoxy by itself has limited tensile capabilities, but when used with carbon stitches, they complement each other as total reinforcement. Stitches hold the tensile load, and the Epoxy or sold crack fill holds the compression of the repair.


Technical Details


Q. What ASTM standards do they meet?
A. The products have been lab tested to meet ASTM C882, D648,D638,D792

Q. How long does the epoxy take to cure?
A. Gel in 1 hour and cure in 24 hours

Purchasing


Q. How many stitches do I need for my project?
A. Spacing: 9–16 inches

Q. Do you offer bulk discounts for contractors?
A. Yes, and we also offer custom-sized stitches .

Maintenance


Q. Can the repaired area be painted or coated?
A. Yes they can be coated after curing.

DIY vs. Pro Use


Q. Are these suitable for beginners?"
A. Yes these Carbon Stitches are one of our easier products to install.


Q. Why do contractors prefer NextStar?
A. Customer support is the most significant factor for our contractors, who often require fast technical assistance or a customized solution.

How strong are Carbon Fiber Stitches?

Carbon fiber is 10x stronger than steel. The holding strength of Carbon Fiber Stitches or even Stainless Steel Staples in concrete is a function of the surface bonding area and not so much the tensile capabilities of a stitch or staple. The concrete will fail before a staple will, So the best reinforcement is to have the most surface bonding area for long-term results.

What gives the best concrete stitching repair?

The product that has the most reinforcement has the most carbon surface area!

The Evolution of the Concrete Staple Stitch

The concrete staple, also as the concrete stitch, is a method used to repair cracked or damaged concrete structures. The process involves drilling holes on either side of the crack and inserting a staple or stitch made of metal or composite materials, which is then anchored to the concrete using epoxy or other adhesive.

The concept of the concrete staple dates back to the 1960s, when it was first introduced as a means of repairing concrete dams. Over the years, the design and materials used in the staples have evolved, and today, there are several types of staples and stitches available.

One of the earliest designs was a U-shaped metal staple, which was inserted into the drilled holes and anchored to the concrete using grout or cement. However, this design had limitations as it could only be used on relatively narrow cracks and was not effective in preventing further cracking.

In the 1980s, composite materials such as carbon fiber and fiberglass were introduced as an alternative to metal staples. These materials offered higher strength-to-weight ratios and improved flexibility, allowing them to conform to irregular surfaces and accommodate movement in the structure.

Today, there are several types of staples and stitches available, including plate staples, which are larger and offer a greater surface area for bonding, and helical stitches, which are twisted or spiraled to increase their resistance to bending and tension.

Overall, the evolution of the concrete staple or stitch has been driven by the need to develop more effective and efficient methods of repairing concrete structures. The use of composite materials has played a significant role in improving the strength, flexibility, and durability of these repairs.
