A Simple Plan For Investigating Foundations

What are the Uses of Helical Piers?

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.

It is recorded that the helical pier technology is more than 100 years old. It is considered as a proven system in new constructions and repairs or renovation works. 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. Helical piers as compared to other systems will prove to be more advantageous especially if the work involves existing buildings.

Helical piers foundations need equipment that are just smaller, lighter and less specialized unlike the equipment used in other kinds of 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 turned in with a torque motor like a wood screw being turned into a piece of wood, and this makes helical piles vibration free when installed that gives it an advantage. Be aware that it is not wise to add structures on an existing structures close by.

The torque should be regularly monitored when contractors are installing helicals in each pier. The contractor usually would know at the end of the installation the load or capacity of each pier since the capacity of each pier is directly related to the torque rating.

After installation, there is no curing time in the case of helical piers installation. Minimal excavation will suffice in a helical pile because it is turned or screwed in. Another advantage of helical piers is that you save on costs of removal and disposal because there are not spoils to be removed from the site.

Noise pollution is drastically lowered when helical piers are installed because of the use of smaller installation equipment that do not require violent hammering or banging.

Those existing foundations that are failing, can be solved using helical piers, and this is another very important advantage of helical piers, aside from being used in new constructions. Instead of removing the present foundation that failed and dispose it in a landfill, the helical piers are used over the present foundation, thereby creating a deep foundation system plus contributes to a green environment.

Several factors would affect your project, and so it is wise to ask the help of structural engineer to see which method would be best for your project.
