All About Helical Piers

Before anything, it is important to know and understand what a helical pier is. A helical Pier is a steel foundation that has helices inside of it, just like a screw. Using a hydraulic system, it is pushed into the ground to depths below the frost line. They are used to support buildings, especially in difficult soil environments where it is difficult to put up a conventional foundation system. They weave deeply into the ground as opposed to using expensive big excavations. They are important in a structure. Helical piers are used to support buildings, especially in difficult soil environments where it is difficult to put up a conventional foundation system. They weave deeply into the earth as opposed to making expensive, huge excavations. They are important because they carry the weight of a building or structure deep into the ground as opposed to having it rest on the surface. For deep foundation projects and structures with poor soil conditions, site-specific constraints, and heavy loads, helical piers are a great option. In much simpler words to make it easier to understand, imagine helical piers as a huge screw that is driven into the ground. In the same way, you would use a screw to hold a picture to a wall, the helical screw will support your home by holding it in place. Helical Piers are quite effective, they can hold heavy weights and anchor the structure in place using an underpinning system. They also outperform other types of piles or deep foundation support systems in terms of speed and cost. Now here is how this works. First of all the area needs to get checked before they start doing prep work. The first is to determine the pier locations and where they are going to go in order o be the most effective along with some mathematical calculations. This is done before the excavation of each pier location. A further 18 inches of excavation are made below the footing. This gives you enough room to carefully hammer down the footing of your home and then snugly install a remedial bracket to it.

After the holes are dug up, the helical pier installation process begins…

● The helical pier is installed using a hydraulic drive head that is connected to a hydraulic power pack or hydraulic pump.

● Once the helical pile has been installed to the desired torque, it is cut to size. On average, this cut happens 18" up from the footing's base to the helical pier shaft that has just been built.

● The foundation of your home is then secured with a corrective bracket using mechanical or epoxy anchor bolts.

● Following bracket mounting, we install a hydraulic lifting jack and fasten our lift component to the bracket.

● We pressurize the jacks and start lifting your house once all of the lift assemblies and jacks have been put in correctly.

● We use a manometer to measure the floor elevations while we elevate a house.

● All of the jacks raise simultaneously as we elevate the house in tandem, but occasionally one region rises more quickly than the others and reaches its maximum practicable recovery.

● We just shut off the valve on the jack once the desired lift has been attained on one portion and let the other jacks continue pressing.

● After the lift is finished, we tighten all of the bracket parts and start the project's backfill phase, which involves filling in all of the areas that were previously excavated.

● Finally, your home has reached its highest practicable level of recovery, the holes have been covered, and it appears as though we never existed.

The design, dimensions, weight, and surrounding soil conditions all affect a helical pier's price. Due to these several factors, the cost of an installed helical pier might vary from $15 to $30 per foot. Therefore, the price per average 20-foot helical pier might range from $300 to $600. Typically, helical pile designers and constructors will predict a lifespan of about 150 years. Between 75 and 350 years is the range of possible lifespans. The soil quality of the location has the most impact on how long a helical pile lasts.
