Need To Fix a Crack in Your Basement Walls?
Guardian Foundation Repair, LLC offers Carbon Fiber Installation services in Knoxville, Johnson City, & the Surrounding TN Tri-Cities!
Carbon Fiber Bands are used when the foundation wall has vertical or horizontal cracks caused by hydrostatic pressure. Hydrostatic pressure is caused usually from poor drainage such as over flowing gutters or clogged downspouts or a negative slope towards the home. When the water has nowhere to go, it settles in a low area and the soil expands causing the basement wall to bow inward and create a long straight crack in the mortar joint of the basement wall. If not repaired the wall would continue to bow inward and a more significant repair would be needed.
Guardian recommends using 8′ x 7″ horizontal carbon fiber bands centered over the vertical crack starting 2′ from the bottom on 2′ centers.
Guardian Foundation Repair installs vertical Fortress Carbon Fiber Systems© for all horizontal cracking caused by hydrostatic pressure.
The Fortress System include a 4″ kevlar reinforced carbon fiber band along with anchors at the top and bottom to securely fasten to the slab below and the floor system above.
The Fortress System Carbon Fiber has a tensile strength of 234,700 psi (4 times stronger than steel).
Carbon Fiber Installation Process
First we grind the wall where the 6″ wide by 8′ tall Carbon Fiber band will be installed. If the band is being applied horizonally we place the material 4′ on either side of the crack. Then we apply a 2 part epoxy to the wall in order for the Carbon Fiber band to adhere to the wall. Next we install the Carbon Fiber band and use small metal plates to secure the ends to the top of the block wall and to the bottom of the block wall. Finally, we apply a heavy layer of 2 part epoxy to cover the Carbon Fiber band.
