Lessons Learned from Years with Construction
Brief Description of a Helical Pier and its Uses
Deep foundation of underpinning elements that are constructed using steel shafts with helical flights are known as helical piers. According to manuals, the shafts are made to bearing depth by twisting the shafts into the soil while the torque is monitored to an estimated pile capacity.
The technology of helical pier is over 100 years old. Considered to be proven for new constructions and repairs or renovation works, this system is well used. This system is proven to be a very effective solution for foundation repairs especially when the soil condition would need installation of piles to be deep. Especially if the work requires on existing buildings, helical piers would have competitive advantages over other systems.
Equipments that are used in helical piers foundation are usually smaller, lighter and less specialized compared to the equipment used in deep foundations. With these … Read the rest
