CHANCE Helical Pulldown Micropile

The CHANCE™ Helical Pulldown Micropile, a patented system, is a composite pile combining CHANCE Square shaft Helical Pier anchors with a grout column formed around the extension sections. The Helical Pulldown Micropile resists buckling in poor soils and also provides additional capacities adding a frictional component to end bearing capacities.

• Additional lateral stability of the pile
• No vibration during installation
• Achieve design loads in given soils
• No excavation spoils - displacement plates 
• Cased or uncased grout columns
• Decreased mobilization costs
• Installs in all weather conditions
• Installs in limited access situation
• Ability to be installed in close proximity to underground services
• Capacity accurately and easily measured using installation torque
