CHANCE manufactured anchors are rated up to 100,000 pounds each. These are available in round or square shafts manufactured from high-strength galvanized steel. Special patented brackets are used to stabilize or lift foundations in distress. CHANCE is the only company with a pre-engineered and manufactured underpinning system evaluated and listed by all the national building code agencies.
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.
