Concrete Push Piers in Savannah, GA

Concrete push piers stabilize settling foundations by driving stacked concrete cylinders beneath the footing until they reach firm, load-bearing soil. It is a proven underpinning method for coastal homes where shallow soils have given way.

How Concrete Push Piers Work

Sections of high-strength concrete are hydraulically pressed into the ground using the structure’s own weight as resistance, forming a column down to competent soil. The foundation load transfers to that column, halting settlement and allowing potential lift back toward level.

What Installation Includes

• Assessment of settlement and soil profile
• Excavation at each pier location along the footing
• Hydraulic driving of concrete pier sections to capacity
• Load transfer with brackets and attempted re-leveling
• Backfill and cleanup

Signs You Need Push Piers

• Settling foundation with stair-step or diagonal cracks
• Sticking doors and windows from movement
• A section of the home visibly lower than the rest
• Prior repairs that did not reach stable soil

How Concrete Push Piers Stabilize Settled Foundations in Savannah

Concrete push piers, also called pressed pilings, are one of the oldest and
most cost-effective underpinning methods used to stabilize sinking foundations
across Savannah and coastal Georgia. The system relies on precast concrete
cylinder segments that are driven straight down beneath a home’s footing using
a hydraulic ram. Rather than screwing into the soil, each segment is pressed
one on top of the next until the column reaches a firmer, load-bearing layer
of soil and can carry the structure’s weight.

The key principle is simple: the weight of your house becomes the force that
installs the piers. As the hydraulic ram pushes each concrete cylinder into
the ground, the mass of the structure above provides the resistance needed to
advance the pier deeper. When the pier stops advancing and holds steady
pressure, the crew knows it has reached soil capable of bearing the load. At
Solid Foundation Repair Of Savannah, we’ve applied this approach to coastal
Georgia homes since 1989, matching the method to the soil beneath each
property.

The Push Pier Installation Process Step by Step

A concrete push pier installation follows a predictable sequence, and
understanding it helps Savannah homeowners know what to expect on the job
site:

• Access excavation: The crew digs a compact access pit
  beside the foundation at each pier location, exposing the bottom of the
  footing.
• Bearing preparation: The base of the footing is cleaned and
  prepared so the pier column transfers load directly to the structure.
• Pressing the segments: Precast concrete cylinders are
  stacked and driven downward one segment at a time with a hydraulic ram,
  using the home’s weight as resistance.
• Reaching refusal: Segments continue until the pier reaches
  the point of refusal on firmer strata and holds consistent pressure.
• Lift and lock-off: Once all piers are set, hydraulic
  pressure can be used to raise the foundation back toward level before the
  load is transferred and secured.
• Backfill: Access pits are filled and the site is restored,
  leaving minimal disturbance to the yard.

Because the equipment is compact, push piers can be installed in tight side
yards and limited-access areas common to older Savannah neighborhoods. If you
suspect settlement, our team can assess the situation during a

Concrete Push Piers vs. Steel Push Piers and Helical Piers

Choosing the right pier depends on soil, structure weight, and how deep stable
strata sits below your Savannah property. Each system has a distinct role:

• Concrete pressed pilings: Precast cylinders driven by
  hydraulic pressure. They offer high compressive strength, strong resistance
  to water and moisture, and cost efficiency, making them a practical fit for
  many coastal Georgia slab and pier-and-beam homes where stable soil is
  within reach.
• Steel push piers: Interlocking steel tube sections driven
  to greater depths. Steel is favored when load-bearing strata is deep and the
  structure is heavy enough to drive the piers to rock or dense clay.
• Helical piers: Steel shafts with helical plates screwed
  into the ground with a torque motor. Because installation does not depend on
  structure weight, helical piers suit lighter loads, additions, porches, and
  very soft or fill soils.

No single method is universally best. The correct choice for your home is part
of a broader
foundation repair
evaluation that weighs soil borings, symptoms, and structural load.

Why Coastal Georgia Soils Demand Careful Pier Selection

Savannah and the surrounding Lowcountry sit on flat coastal plain soils with a
high water table, expansive clays, and pockets of sandy fill. These conditions
cause soil to swell and shrink with moisture cycles, undermining footings and
producing the cracks, sticking doors, and uneven floors homeowners notice.
Concrete push piers perform well in these settings because concrete resists
the constant moisture and because pressing to refusal bypasses the unstable
upper soils that move with the seasons.

That said, coastal water tables and variable fill mean the depth to reliable
bearing soil is not always shallow. Where stable strata sits deeper than
pressed concrete can practically reach, steel or helical systems may be the
better engineering answer. This is precisely why an on-site assessment matters
more than a one-size-fits-all sales pitch. Our crews read the specific soil
profile at each Savannah address before recommending a pier type.

What Homeowners Can Expect From Push Pier Repair

Push pier repair does more than stop further sinking. In many cases,
controlled hydraulic pressure can recover a portion of the lost elevation,
closing cracks and improving door and window operation as the structure
returns toward level. The amount of achievable lift depends on how long the
home has settled, the soil, and the structure itself, so realistic
expectations are set during the estimate rather than promised in advance.

The benefits of a properly designed push pier system include a permanent
transfer of the foundation load to stable soil, minimal landscape disruption,
and a fast installation compared with full foundation replacement. As a
