Power-installed
screw anchors have proven to be a reliable and economical
advancement in foundation technology. Chance Helical Pier
Foundation Systems anchors and related hardware are available
in a wide range of sizes to meet many job applications. Chance
also offers such unique product resources as:
|
- Training and field
supervision of certified installers;
- Geotechnical engineering
guidance for any job;
- Computer-assisted design
capability through interactive software programs and a
field manual bringing design theory to practical field
application.

The system components include solid steel
shafts of round or square configuration to most economically
meet any design-load requirement. The standard underpinning
bracket typically comes complete with the hardware required
for assembly to the Helical Pier Foundation Systems anchor
shaft. The lifting assembly, consisting of the underpinning
bracket and jacking tool, is designed to lift with hydraulic
jack assistance.
Hardware is also available for specialized applications, such

problems caused by poor soil conditions. For seismic uplift loads,
the Uplift Restraint Bracket may be added. |
 |
| Heavy
Duty Bracket |
For
such higher loads as commercial buildings and larger residences.

 |
| Uplift
Restraint Bracket |
For
seismic conditions and to resist other upward forces. Shown as
applied, assembled to top of Standard Duty Bracket. |

| Slab
Bracket |
For
stabilizing uneven or damaged floors. Bolt adjusts through cap
