Bowing Walls

Bowing walls occur when a home’s foundation walls curve inward, forming a “bow.” The most common cause of a bowing or leaning wall is excessive lateral pressure on the exterior. When the pressure becomes too much for the wall to handle, it starts to bow, crack, or even break.  Common causes of bowing walls come from the following:animation of bowing wall underground

  • Expansive clay soils expand and contract as the moisture in the ground increases and decreases.
  • Hydrostatic pressure, which is an accumulation of water in the soil surrounding the foundation wall that is exerting pressure against the wall.
  • Frost can also lead to bowing walls as the soil against the wall freezes and applies pressure.

 

 

*It’s important to remember that damaged foundation walls are an indication of a serious problem for the home.

To repair bowing walls, we use a variety of products and techniques:

Wall Braces

When pressure from soil movement begins to cause bowing walls, braces can be used to counteract the stress. The Force Brace is a patented structural tension-loaded, steel l-beam system that is designed to straighten block or concrete walls over time. The Force is recommended when wall plates cannot be used because of yard restrictions or other obstacles. Without excavation or homeowner assistance, The Force’s unique l-beam/spring-coil design supplies a constant 1000-pound force on bowing walls.

  • Can straighten wall over time without excavation
  • Can straighten wall immediately with excavation
  • All parts are American steel
  • Can be installed when both interior and yard access is limited
  • 10 year transferable limited warranty

Bowing walls are caused by excessive lateral pressure on the exterior. When the pressure becomes too much for the wall to handle, it begins to bow, crack, or break, and many times will even start shearing in towards the bottom. When this happens, contractors install wall anchors on approximate 6’ centers that stop further movement and, with proper tension, will eliminate the bowing over time. The installation of wall anchors allows weight to be evenly distributed up the entire height of the wall and stops not only the inward movement, but also the bottom shear of the wall.

  • Quick and minimally invasive installation
  • Limited disturbance to landscaping and yard
  • Will not interfere with most framing
  • Application done from inside basement
  • Can straighten wall over time without excavation
  • Can straighten wall immediately with excavation
  • All parts Galvanized American Steel
  • 25 year transferable limited warranty on C-Channel wall anchors

 

 

 

Carbon Fiber

Carbon fiber is a high-strength fabric material that won’t stretch and is virtually unbreakable; in fact, it’s used in the construction of commercial aircraft. Rhino Carbon Fiber wall supports are part of the market’s strongest patented system because they tie to the foundation base and house framing. The carbon fiber is fastened to the sill plate with a galvanized bracket and secured to the foundation floor with a carbon fiber pin. Deterioration does not occur because the carbon fiber system is secured to the foundation wall, allowing for an even distribution of outside pressure.

  • Quick and clean installation
  • Works on block and poured concrete foundations
  • Ties in footer wall and sill plate for complete protection against any movement
  • Complete stabilization
  • Limited lifetime warranty
