Carbon Fiber Strapping
There are two different types of cracks which develop in basement walls: one due to flexure (referred to as "out-of-plane" loading); and the other caused by shear ("in-plane" loading). Flexure cracks are typically horizontal and may travel to the corners of your basement wall. Shear cracks are typically diagonal along the wall with the bottom being narrower than the top.
Bowing occurs when the pressure and stress forces impact a larger area and push the foundation wall out of plumb. Dry Basement Solutions treats substantial cracks and bowing of more than 2” with carbon fiber strapping. (For smaller cracks we use polyurethane caulk injection, urethane foam grout, or hydrophobic urethane injection.)
Modern carbon fiber materials provide a cost-effective answer to these foundation stresses. These fibers have remarkable strength and can enhance the flexural capacity of steel reinforced and un-reinforced masonry walls by over four times the original capacity – while simultaneously providing waterproofing.
