They use collars on the piers to create voids for addition of grout and centralizer disks to keep the pier centered in the grout column.&lt;br /&gt;
Video using 2&amp;quot; x 2&amp;quot; steel piers:&lt;br /&gt;

Fortress Foundation in Little Elm, TX appears to use the above piers for new construction:&lt;br /&gt;

Another company explaining pier installation on soil that varies in density. They install them to 5900 ft lb torque:&lt;br /&gt;

This video is about a telescoping drive head:&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Installation torque is critical and I see two methods of measuring it:&lt;br /&gt;
strain gauge&lt;br /&gt;
differential pressure in hydraulic lines&lt;br /&gt;
&lt;br /&gt;
In this video, they say the helical pier was developed by an Irish man for a lighthouse:&lt;br /&gt;
