Foundation repair using the A.B. Chance Helical Pier Foundation System is a patented stabilizing system, offering a technically superior and more cost effective alternative for stabilizing a structure. The concept is founded on the principle of turning a screw anchor into subsoil strata until the torque applied indicates the necessary load capacity has been achieved.
There are 3 effective applications for the A.B. Chance system:
- Underpinning of an existing foundation to support the foundation and or interior floors
- New construction to incorporate a load bearing pile
- Tie Backs for seawalls and retaining walls
This is a "NEIGHBOR FRIENDLY" system : NO CRANES - NO POUNDING - NO VIBRATION
Cracked foundations, sinking foundations, buckled walls, & uneven floors are problems commonly faced annually by some quarter million homeowners. Homes and other structures situated on unstable soils settle when their foundations are subjected to extreme moisture conditions or lack proper drainage. A shifting foundation may result in structural damage to your home and a loss of your investment.
Indications of foundation settling problems include:
- Foundation walls that are buckled or bowed
- Doors and windows that stick or don't open properly
- Cracks in foundation walls
- Cracks in exterior walls
- Cracks in interior walls and ceilings
- Sunken or buckled interior concrete floors
Once your CHANCE certified installer has received the plan of repair from a qualified design group or individual, he can proceed with the repair. Remember, one of the best investments you can make is to get a soil boring on your property. This will enable the designer to determine what type of anchor and to what depth it must go to stable soil. Usually the installer will excavate a hole at each anchor location wide enough and deep enough to place a bracket under the foundation. The leading section of the anchor with the proper number and size of helices will be installed by a rotary installing machine. Extensions are added until the helices are at the proper depth and the predetermined torque is achieved. At that point the bracket is added, the load is transferred to the anchor, and the building can be stabilized or lifted according to the plan of repair.
