12 inch 300 GSM Uni-Directional Carbon Fiber Fabric Grade 1   (grams per square meter)

300 GSM is perfect for Poured or Block walls with cracked walls or curved applications to prevent re-cracking.
Ideal for a contractor as general use carbon fiber for concrete reinforcement. Unidirectional carbon provides the best carbon fiber application solution as it has the least elongation or stretch before it is under full load.  Woven Carbon fabric from others allows for much more movement of the concrete crack, and joint and may contribute to the failure of the intended repair. Account for a maximum spacing when reinforcing block or poured walls of 4ft vertically or horizontally. Wide uni-directional carbon fiber has advantages when bonded to weak or compromised concrete to spread out the loading stresses to prevent debonding under high-stress loads. Weak or poor concrete will generally fail long before and carbon fiber will. To increase the loading on such concrete it is best to increase the bonding area with wider unidirectional carbon fiber or use multiple strips applied side by side to achieve this. Use externally on cracked outside corners of foundations to prevent wall separation.

Applications of 300gsm Unidirectional Wide Carbon Fiber

use as Carbon fiber wall strap Reinforcement to Poured or Masonry Block walls
Block or Poured concrete walls Use to form Carbon Fiber Wall Straps
Carbon fiber corner wall kit Use as Carbon Fiber Wall Corner Straps
Block or Poured concrete walls Wide Carbon Fiber for weak or compromised areas
Retaining walls Retaining walls
Reinforce concrete corners Reinforce exterior concrete corners
Support window openings or lintels Reinforce foundation window openings or lintel
Carbon Fiber fabric can be used horizontally n concrete walls Use horizontally to bridge openings

Steps of Application of the Carbon Fiber

1. Prepare any wall cracks if a poured wall using Epoxy Crack Injection if a block wall re-tuckpoint any broken mortar joints.

2. Using a diamond cup wheel with a grinder and dust shroud, decontaminate the concrete surface and vacuum all dust off the concrete wall surface.

3. Layout carbon fiber on a clean surface to cut to proper length as needed.

4. Mix the Startech Epoxy 2:1 ratio in a mixing cup

5. Apply some epoxy to the concrete surface approximately 6 in wide where the carbon fiber is to be installed using a trowel and roller. Also roller one side of the carbon that is to be applied.

6. Apply the fabric to the concrete with the epoxy coated side toward the wall and using the roller supplied, roll the material while adding more epoxy.

7. At this point, using the square trowel supplied and using the flat side trowel, the epoxy into the fabric to work it into the Carbon Fiber Strap. Make sure that you have the carbon fabric held down so it does not move.

8. Re-roll the fabric to smooth out the epoxy and add more epoxy as needed.
