CHANCE® deep foundation systems are a great solution when shallow foundation solutions will not carry the load. Deep foundation solutions transmit the structural loads to soil/rock that is deeper in the ground. CHANCE products are ideal due to the speed of installation, their resistance to buckling in weak soils, added corrosion protection and more.
CHANCE helical piles for deep foundations are composed of pre-manufactured steel and feature a central steel shaft with one or more helical shaped bearing plates. A helical pile is installed by rotating or screwing it into the ground. Each helical bearing plate is formed into a screw thread with a uniform defined pitch.
The CHANCE Helical Pulldown® micropile is a system for constructing a grout column around the shaft of a standard helical pile foundation system. The micropile does not require removing spoils from the site. Combining both end-bearing on the helical plates and skin friction along the rough surface of the grout column increases the buckling and compression capacity for the pile system.
