Helical Pier Installation

We are your go-to helical pier installers. Helical piers are a great way to tap into the bedrock of your existing site.

 

How it works:

The helical piers are driven into the ground methodically with a special hydraulic driver powered from either a skid-steer or excavator. The lead is the first piece to be driven and has either one or multiple helixes welded to the shaft of the pier. The piers usually consist of approximately 7' or more in length, with extensions being added consequentially to achieve the engineered resistance pressures. Once the pressures are achieved, all required measurements are recorded, and the end is terminated to desired height. The benefits of helical piers are many, including no extensive excavation or curing time of concrete, instant compressive strength, economic efficiencies, and no disruptive earth movement and noise created to existing structures and neighbors.

​

A list of applications used include:

• New Residential & Commercial Foundations

• Electrical Poles and Light Poles

• Decks, Porches, Walkways, & Boardwalks

• Seawalls (Tension Piles

• Foundation Repairs

• Guy Wires for Telephone Poles and many other uses!

​

We are trained and certified by Pier Tech Systems Inc., a leading helical pier distributor and manufacturer. We have partnerships with them as well as local engineers to assist, if necessary, in the design of your project's foundation. 

​

We are proud to be established subcontractors to various local builders in the area and have exceptional quality control in our helical installation.

​

For our contractors, please have a soil report, plans, and specifications available and we can provide a quote over the phone.

​History of Helical Piers

              Helical piles or piers have been around since the 1800s. They were invented by a blind, Irish bricklayer & engineer named Alexander Mitchell in 1833. Their first uses were for the moorings of boats and were found to be an exceptional way to anchor into sandy wet soil conditions. Not long after Mitchell's invention, helical piles became a very popular method of construction for piers and lighthouses, that were a much-needed safety measure to secure the passage of goods and the lives of the sailors entering the harbors during bad weather or heavy fog. Before this invention, there was no way to build lighthouses in the soggy, wet soils of the marshes. Helical piers were even used in the construction of the lighthouses at both Sand Key and Sombrero Key in the Florida Keys.​​​​​​​​

​

During the 1920s-1980s, helical piers became very popular in the use of tie-wire hold downs and tension applications in an era of utility use. As of 2009, the International Building Code adopted helical piles into code. 

With over 200 years of time-tested construction, helical piers have proven to be an invaluable economical and technological advancement in deep foundation building systems.
