What is Helical Piers:
A helical piers is basically a giant screw that is driven deep into the earth until a capable, load-bearing level or base is reached. It is then attached to the feet of a failed foundation for support.
Repair a cracked foundation or are thinking of leveling your house, a helical pier system may be right for you. helical piers work by transferring the load of your home to the load-bearing soil. When the piers reach the load-bearing soil, a steel foundation bracket is attached to the foot of your house and attached to the helical piers.
This transfers the weight of the house to the stagnant soil, clogging the settlement. From there we can try to restore your home to its original condition. The helical mooring system is perfect for permanently preventing foundation settlement, thus avoiding structural failure.
Helical piers are ideal for you if you want these four things:
1: A quicker installation compared to other systems.
2: A permanent solution.
3: To bring the home to its original position.
4: To stabilize a lighter structure that has started to sink such as a deck or a chimney.
Foundation Repair Process using Helical Piers:
- The process begins when a pier tech certified installer performs a site survey the installer will mark the building electrical and gas lines and a location for each pier then the excavation process begins either by hand or by machine.
- holes are dug in the location for each pier this reveals the footing and allows for proper bracket placement once the holes are excavated to proper depth the footing must be notched to create a flat and smooth surface for mounting the bracket using a bobcat the helical piles can now be installed.
- the technician continually monitors pressure and torque patented cross-bolt connection eliminates all unwanted movement in the piles
- once the pile reaches design depth then load-bearing strata the pile is cut off at the proper height lift bracket is then installed backward rotated under the foundation
- the true lift bracket has been patented to draw into the foundation providing a more reliable and stable permanent solution
- once all piles have been driven and all brackets installed they are locked down and the house can now be raised using a hydraulic jack
- each pile assembly is raised into the foundation this careful process brings the house back to the level it.
- loosens doors and windows and in many cases, it closes cracks once the foundation is successfully stabilized all holes are backfilled and every effort is made to return the landscape to its original condition
Advantages of Helical Piers:
- It can save you from having to replace your entire foundation.
- They are suitable for both heavy and light loads.
- They reach greater depths than other options.
- Our round shaft design resists bending.
- Our helical Pier system has a patented bracket and external sleeve that also prevents kinking and bending.
- Our system is available in galvanized steel that resists rust.
- It’s underground.
- Our helical Pier system can often lift foundations back to their original position.
Disadvantages of Helical Piers:
- The installation can be disruptive to your yard as helical piers require the use of moderately heavy equipment to install.
- They require an expensive soil boring sample or intimate knowledge of the local soil.
- They can bend.
- Not all helical pier systems are created equal.
Cost to Install Helical Piers:
- The average general contracting cost for a pier is $1500-$2500
- peers with or without a death clause peers without a depth clause will run 250$ more per-peer due to unknown depth. peers with a depth clause will be cheaper but you run the risk of additional costs with additional installation depths. those costs are about 75$ per linear foot beyond the first 21 feet that are included.
- Concrete piers cost around $30-$230 installation time 2 to 3 days.
- helical piers are priced based on three things:
- the size of the helical pure material
- the depth of the helical pier needs to be installed
- the access to the areas where the helical piers are going to be installed
- size does matter helical piers come in all different shapes and sizes the general rule of thumb is the bigger the pipe and the bigger the cost.
- helical piers are classified on the diameter of the pipe that the helical is welded to larger helical piers such as the 3.5 inch all the way up to 24-inch diameter will carry a higher material cost as the pier goes up
- the larger piers require larger equipment to install them and larger equipment requires more room to navigate and garner access almost all residential projects require 2.78-inch helical pure material these vehicles have a load capacity of about 74 kips which is 74 000 pounds in layman terms
- the insulation depth of each of these piers also plays a major factor in the pricing just like with the size the deeper the depth the deeper it bites into your pocketbook, for example, the pier needs to be installed at a depth of 40 feet to achieve the desired load capacity versus 20 feet
- there will be an increase in price due to the cost of the additional 20 feet of material we promise construction companies aren’t trying to hit oil it’s imperative we reach competent depths that will support your home or business.
