Carbon Fiber and Foundation Repair
Carbon Fiber Products are used to repair bowing walls on both block and concrete foundations. However, block walls are far more likely to bow and therefore need these types of repairs much more frequently than poured concrete walls. There are 3 basic carbon fiber products that can be used for foundation repair problems.
4″ CARBON FIBER STRIPS (also known as Carbon Laminates)
Carbon fiber strips are about as thin as a dime (0.05″), but their tensile strength is stronger than steel. These strips or laminates are used to repair bowing walls that are not deflected more than 2″ laterally. BDry properly prepares the wall and applies them with a tough epoxy, creating an extremely strong bond. The application fully cures in 3 to 5 days and is paintable in 24 hours.
10″ UNI-DIRECTIONAL FLEXIBLE FABRIC
This is a flexible carbon fiber mesh material that is also used to stop bowing in block or concrete walls. The tensile strength of this 10″ fabric is about the same as the 4″ strips/laminates.
The uni-directional carbon fabric may be used, instead of laminate strips when the block wall is bowing and the mortar joints are out of alignment, or if the masonry components are somewhat loose or deflected. The 10″ fabric adds stability to more of the individual blocks.
12″ BI-DIRECTIONAL FLEXIBLE FABRIC
This product is used to repair cracking block walls. The cracks can be vertical, horizontal or diagonal. The thickness of this material is 0.047″. It fully cures in 8 days and is paintable in 3 days.
