In Tampa, a dock that sags, a lift that tilts, or a pool deck that drops toward the seawall is usually fixed by carrying the load down to firm soil with helical piers, or by filling the voids that formed underneath.

Almost every case traces back to ground that is too soft to carry the weight, or soil escaping through the wall.
A good share of waterfront Tampa is man-made. The City of Tampa says Davis Islands was raised from two small keys using mud dredged from the bottom of the bay (City of Tampa). Under lots built that way you often find:
Recent storms added stress. Helene flooded nearly every street on Davis Islands in 2024, according to FOX 13, and a flood that deep saturates fill, then leaves it to settle unevenly as it drains.
Steel shafts with screw plates are turned into the ground until they hit soil that can carry the load. Installation torque tells us when that point is reached. We then bracket the pier to the structure and lift it back toward level. It suits docks, lifts, decks, and light buildings. See helical pier installation.
Where water has carried soil out from under a pool deck or patio, we inject polyurethane to fill the gap and stiffen the ground. Slabs can often be raised back into place without breaking them out.
Pilings damaged by rot, borers, or storm debris can be jacketed, wrapped, or supplemented with new supports.
If fill is leaking through the seawall, leveling the deck alone won't last. We pair it with bulkhead repair in Tampa so the ground stops moving.
Marine foundation repair in Tampa typically costs $700–$2,000 per helical pier and $8–$25 per board foot for void fill. Most residential marine foundation repairs run $5,000–$25,000, depending on pier count, depth to firm soil, and access.
It depends where you are. Port Tampa Bay requires a permit for structures in Hillsborough County located at, on, or over tidal waters, including the Hillsborough River, and even a floating platform needs one (Port Tampa Bay). EPC runs the Minor Work Permit program that handles much of this review.
Along the Hillsborough River, the City of Tampa stopped issuing its own construction permits for dock and boat-lift work. Those projects now go through Port Tampa Bay and EPC, with a recommendation from the river planning board's technical committee. When a repair grows into a full rebuild, see marine construction in Tampa.
Yes. Our Tampa seawall repair hub lists every service in the city, and we also stabilize docks and slabs in St. Petersburg and Bradenton.
For docks along the river, permitting runs through Port Tampa Bay and EPC's Minor Work Permit process, not a City of Tampa building permit. We confirm what your specific repair needs.
Usually. If the pilings are sound but have settled, we add support and re-level. Damaged pilings can be replaced one at a time.
Flooding saturates the fill under the slab, and some of it can wash out through the wall as water drains. We check the wall and the soil together, because fixing only the slab won't hold.
As deep as needed to reach firm soil, which varies from one lot to the next. We confirm each pier's capacity during installation.
