New Construction FoundationsThe CHANCE HELICAL PIER® Foundation Systems are designed, tested, and proven for applications in expansive soils, high water tables, fill areas, and other areas where unstable soils require piering.CHANCE is the only company with a pre-engineered and manufactured underpinning system evaluated and listed by all national building code agencies. On reinforced footing or stem walls, the new construction HELICAL PIER Foundation Systems anchors are usually placed every 8 to 10 feet depending upon the load of the structure and the bearing strength of the soil. A two man crew with a skid loader can place over 50 anchors ready for loading in less than one day. Anchors rated by the building codes for working loads of 10 to 20 tons are typical. |
 AdvantagesThe screw pile foundation system is known for its ease and speed of installation. Installation generally requires no removal of soil, so there are no spoils to dispose of. Installation causes a displacement of soils for the most part. However, in the case of a foundation with a pipe shaft, some soil will enter the interior of the pipe until it becomes plugged.Installation equipment can be mounted on vehicles when required. The installation of a screw pile foundation is for practical purposes vibration free. These features make the screw pile foundation attractive on sites that are environmentally sensitive. Installations near existing foundations or footings generally cause no problems. However, the screw pile foundation generally cannot be installed into competent rock or concrete. Penetration will cease when materials of this nature are encountered.
