For foundation underpinning, we use the CHANCE® system.
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.
Only after we have Engineered a Plan of Repair do we start your repair project. Remember, one of the best investments you can make is to get a soil boring on your property. This will enable us to determine what type of anchor and to what depth it must go to stable soil. Usually we 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.
The proven and reliable system for correcting foundation problems. The solution to your foundation problems comes from the world leader in screw anchor development. CHANCE® anchoring systems, widely used since 1907 in thousands of construction projects, brings the finest in materials, service and quality to your foundation. All dealer/representatives are thoroughly trained and certified in installation procedures and are supported by the extensive technical-support services of CHANCE®
Sinking foundations, cracked and buckled walls and 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:
