What are the Uses of Helical Piers?
Known as helical piers are deep foundation underpinning elements that are constructed with the use of steel shafts with helical flights. By twisting the shafts into the soil with advanced bearing depth, the torque is also monitored to reach a pile capacity.
Helical pier technology is said to be well over 100 years old. It is considered as a proven system in new constructions and repairs or renovation works. Where the soil condition requires deep piles for installing foundation repair, this system is said to be a very effective solution. Helical piers as compared to other systems will prove to be more advantageous especially if the work involves existing buildings.
Equipments that are used in helical piers foundation are usually smaller, lighter and less specialized compared to the equipment used in deep foundations. In this case, the cost of moving in and moving out or mobilization is usually lesser than other systems. These conditions allow contractors then to go in tight or confined areas in helical piles installation as compared to the larger equipment which cannot fit into the area.
Helical piers are also advantageous in the sense that they are installed vibration free because they are turned in with a torques motor similar to a wood screw that is turned into a piece of wood. Remember that it is not advisable to work on additional structure on neighboring properties with already existing structures.
The torque of each helical pier should be continuously …
