Helical Piers in St. Marys, GA
St. Marys porches, anchored below the water table.
Near the river the groundwater sits high and the soil stays wet, which softens the ground under porches and decks. Helical piers reach down to soil that holds.

Why St. Marys homes need this, and how we do it
In St. Marys the river is never far, and the tidal groundwater sits close to the surface. Soil that stays saturated loses strength, so the porches and decks built near the water start to settle as the ground beneath them softens. You notice a deck sloping toward the yard, or a porch step that has dropped below the door.
Helical piers are built for this. We screw galvanized steel piers through the wet, weak upper soil to firmer load-bearing strata below and log the torque as proof of capacity, then bracket the deck or porch to them. The piers screw in with little excavation, which is a real advantage on soggy ground where a big dig would only make a mess.
After the load transfers to the piers the settling stops and we can often bring the porch or deck back toward level. Galvanized steel holds up well in the damp, salty conditions near the river that rot wood posts and shallow footings. Lighter porches and decks suit helical piers, and where a heavier masonry section is involved we turn to push piers, sorted out during the free inspection.
What’s included
What a helical pier installation includes
Every helical piers we do in St. Marys, GA follows the same checklist. Every pier is engineered, verified and logged. A typical installation includes:
- Soil, load and depth assessment before any pier is specified
- Pier count, spacing and locations set by the engineering, not by eye
- Excavation at each location with spoil kept off your landscaping
- Helical shafts advanced to verified torque rather than a fixed depth
- Steel foundation brackets tied into the existing footing
- Controlled load transfer, with a lift attempt where the structure allows
- Installation log with depths and torque, plus before and after photos
What we won’t do
We will not quote a pier count over the phone, we will not drive piers to a depth instead of to measured capacity, and we will not promise a lift a structure cannot take. What is realistically achievable goes in writing before you sign anything.
What to expect
Four steps, start to finish
Free inspection
We look at the cracking and separation, measure elevations, and work out what is moving and what it weighs.
Engineered plan & fixed price
Pier count, spacing, depth expectations and price, all in writing, with financing options alongside.
Install
Access is dug carefully where it matters, piers are turned to verified torque, and brackets are set to the footing.
Load transfer & warranty
The load moves onto the piers, the ground is backfilled and restored, and you get the installation log and warranty.

Questions St. Marys homeowners ask us
My deck near the St. Marys tidal river is sinking, is the wet soil to blame?
Yes, soil near the tidal river stays saturated and soft, so a lighter deck on shallow support sinks. Galvanized helical piers screw down past the wet ground to firm strata and hold the deck steady with little digging.
The porch out back is sloping toward the water, can that be leveled?
A porch sloping over saturating riverside soil is a good helical pier job since they reach the load-bearing layer below. We log torque per pier so you know the lift holds.
Does the tidal moisture rust out the piers here?
We use galvanized helical piers, and the coating stands up to the damp riverside conditions much better than bare steel. That keeps a lighter deck or porch supported over time.
Will this be a big muddy dig next to the river?
No, helical piers turn into the ground so the site stays cleaner and disruption is low, which suits lighter decks and porches. A heavier masonry section would call for push piers.
How do I tell which pier type my riverside deck needs?
Lighter decks and porches on saturating soil usually suit galvanized helical piers because they generate capacity as they screw in. Our free inspection with a written report confirms it.
“Our floors had gotten soft and the whole downstairs smelled musty. They inspected the crawl space, showed us photos of the rot and moisture, and fully encapsulated it. The smell is gone, the floors feel solid, and our humidity finally stays under control.”
