Questions, with the limits left visible.

A helical pier, also called a helical pile, is a steel shaft with one or more helical plates. It is rotated into the ground and can carry compression, tension, or both, depending on the design. Other names include screw pile and helical anchor. The practice behind this site installs steel helicals. Wood and concrete are not helical products in this system, even though a general definition sometimes lumps every pile material together.

No. They are advanced by rotation, the way a screw advances. Hydraulic jacks in some gallery photos are for lifting or holding an existing footing. They are a different tool. Nothing on this site means every pier is vertical. A design can call for plumb piers, battered piers, or both.

The existing site lists common signs: diagonal cracks at openings, doors or windows that stick, sloping or springy floors, gaps at walls, stair-step cracks in masonry, a porch pulling away, and white mineral staining that can mean water moving through masonry. Those signs are reasons to have someone look. They do not, by themselves, prove that a helical pier is the right repair.

The existing site describes five recurring conditions: loose sands and soft organic soils, high groundwater, storm scour, salt exposure, and clays that shrink and swell. Helical piers are one way to reach a deeper layer. They do not erase those conditions. Corrosion, scour, uplift, lateral load, and frost — uncommon as the governing check on this coast, still the engineer's to make — are reviewed for the actual site.

The existing site says that in many coastal South Carolina, North Carolina, and Georgia places the practice has described depths of about 20 to 50 feet, and about 20 to 40 feet along the Grand Strand. That is a published typical range, not a specification. Depth follows the soil, the load, and the engineer's stop criteria. A boring, when one exists, beats a range.

Torque is measured while the pier is rotated, and it is written down. It can be correlated to capacity only when the engineer accepts that correlation for the shaft, the helices, and the soil. A reading is not a substitute for the design, and it does not by itself prove the design load.

The existing site's published typical is 1 to 3 days for a residential underpinning of about 8 to 20 piers, often a day for a new-home array, and longer for a large commercial footprint. Occupied houses are a normal part of that description. It is not a schedule this preview can promise. Gates, height, tides, and obstructions change the work.

The existing site says yes, and calls it a common request: helical piers under posts and beams, then re-shimming, with joist and beam repairs when the wood has failed. That is structural work. A vapor barrier alone does not lift a floor. Equipment has to fit the crawl space.

A concrete pier is a different element. It is cast, it needs excavation or a drilled hole, and it has to cure. A steel helical pier is rotated, usually with less spoil, and the steel section does not wait on a cure. Which one belongs on a site is an engineering choice. Soft holes, access, and lateral load can favor either system. This page does not rank them as a winner.

Building officials in South Carolina, North Carolina, and Georgia see helical products regularly. A current evaluation report — ICC-ES or IAPMO — is one document a reviewer may ask for. The existing site says its systems carry that kind of report. It does not publish the report number, so this preview does not invent one. A report is not a permit, not a flood-insurance decision, and not approval of a particular house.

No price list is published here. The existing site's markup included a generic price symbol and no dollar amounts. Cost moves with the number of piers, depth, helix layout, shaft, brackets, corrosion protection, access, mobilization, engineering, geotechnical information, permitting, repair versus open ground, obstructions, and how much documentation is required. A project brief is a way to describe the work. It is not a quote.

The existing site lists 22 coastal counties: in South Carolina, Horry, Georgetown, Charleston, Colleton, Beaufort, and Jasper; in North Carolina, Brunswick, New Hanover, Pender, Onslow, Carteret, Craven, Pamlico, Hyde, Dare, and Currituck; in Georgia, Chatham, Bryan, Liberty, McIntosh, Glynn, and Camden. It describes that as the stretch from Corolla to St. Marys. It also says to confirm a specific location. No street address or branch office is published, so none is shown.

The existing about page says the practice is licensed to do this work in South Carolina, North Carolina, and Georgia, that it carries general liability and workers’ compensation, and that licensed structural engineers are part of the team. It does not give license numbers, engineer names, or an insurance carrier. Those blanks stay blank until the owner confirms them for this brand. TrueLine Helical is a working name, not a statement that a new company has been formed.

Warranty duration and terms are not stated on the pages audited for this preview, so none are stated here. One county paragraph on the old site mentioned a long corrosion warranty. That sentence is not carried forward without the actual warranty document.
