As Magnum is committed to testing and improving products, these specifications are subject to change. Additional product specifications available at www.magnumpiering.com and in the Magnum Helical Pile Engineering Manual available upon request. Structural capacity is for piles in firm soil with fully braced pile cap. Structural capacity takes into account corrosion over IBC design life in moderate to high corrosive soils based on ICC-ES AC358. Consult a Magnum corrosion engineer for severe corrosive soils.Improved Penetration into Dense & Cobble Soils, Cuts Through Many Fills/Trash,Eliminates Wobble, Maintains Plumbness, Less Soil DisturbanceMagnum's patent pending reinforced helical pile to torque motor connection design increases the torsional capacity of the pinned connection to the torque motor and therefore increases the pile's ultimate capacity by approximately 10%.
