Foundations
Steel in the ground. The record on paper.
A helical pier here is a steel shaft with helical plates, rotated into the soil until the engineer's stop criteria are met. It is used under new buildings and under buildings that have already settled. Marine and boardwalk work is one of the applications below.
new-construction
New construction
Houses and other new buildings where the engineer wants steel piers instead of a shallow footing.
The existing site describes helical piers for new homes: a shaft with helical plates is rotated into the soil, then capped for the footing or grade beam. There is no concrete cure on the pier itself. The building still waits on the engineer's connection details, inspections, and the rest of the structure. A published description of typical new-home arrays says they often install in a day. That is a published typical pace, not a completion promise.
underpinning
Underpinning
Existing foundations that have settled, where a bracket ties the footing to a new pier.
Photographs in the owner's gallery show brackets and jacks at concrete and masonry walls. The jacks lift or hold the structure. The helical pier is advanced by rotation. Whether a wall should be lifted, and how far, is a structural decision. The existing site's published typical for residential underpinning is about 8 to 20 piers over 1 to 3 days. Access, the building, and the soil change that.
crawl-space
Crawl spaces
Sagging floors where the repair is the support posts and the wood, not a vapor barrier alone.
The existing site distinguishes this work from encapsulation. The published scope is helical piers under failing posts or beams, then sistering or replacing rotted joists and beams, then re-shimming the floor. The source text sometimes joins two different systems in one name. This preview keeps them separate. These pages describe helical piers, which are rotated. A push pier is a different tool and is not the system described here. Compact equipment can fit some crawl spaces. It does not fit every one.
decks
Decks, porches, and additions
Lighter structures that still need their own loads, uplift, and connections checked.
Gallery photos show deck brackets, elevated framing, and additions are a repeated topic on the existing site, along with sunrooms and screened porches. Those loads are not the same as the main house. On the coast, uplift and lateral load often govern a porch or deck. The engineer specifies the bracket and whether the pier is plumb or battered.
commercial
Commercial buildings
Warehouses, metal buildings, and other commercial frames when the design calls for helical piles.
The existing site's articles and resource list cover commercial buildings, metal buildings, and heavier pile sections sold by the manufacturer it names. This preview does not repeat capacity tables from those flyers. A commercial pile is still sized from the reactions, the soil, and the product evaluation the engineer chooses to rely on.
public
Public work and waterfront structures
Boardwalks, tiebacks, and other civic or waterfront structures. One application among the rest.
The gallery includes a timber boardwalk on steel posts and a diagram of a helical tieback. The existing resource list also mentions utility and specialty foundations. Those are applications of the same steel helical idea, subject to design, access, and permitting. A boardwalk over soft ground is not a claim that every foundation is in the water, and it is not a named public client.
