Deep foundation features
Any contractor can tell you that a structure is only strong as its foundation. A deep foundation is used when a shallow foundation is not possible, not practical, or will not carry the load, such as in weak, unstable, or expansive surface soils. Proper site preparation and installation is key to the success of any job - starting with the foundation.
Structural integrity
Our 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.
Uniform pitch
Our 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 for precise installation and minimal soil disturbance.
Increased capacity
The Chance Helical Pulldown® micropile is a method of 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. The result is a helical pile with a composite steel/grout section that is similar to drilled and grouted micropiles or auger cast-in-place piles.
