New Bulkhead Construction

New bulkhead construction is the most involved thing we do on a residential shoreline, and it is the work where the difference between contractors shows up years later rather than on handover day. Anyone can make a wall look right on the day it is finished. Making it still look right after a decade of tide cycles, storm surge and soil pressure is the actual job.

Before anything gets built

The quality of a bulkhead is largely decided before a pile goes in the ground.

Survey and alignment. We establish where the wall is going relative to your property line and the water. On a replacement this is also where we work out whether building in front of the existing wall is viable or whether the old structure comes out.

Soils. What is behind and beneath the wall determines embedment depth, tieback design, and in some cases the material choice. Sandy soils, organic layers and the depth to firm bearing all change the engineering.

Exposure. A sheltered creek frontage and a stretch of open river with fetch and boat wake are different design problems, even if they are a mile apart. Exposure drives cap elevation and how the toe is protected.

Loads behind the wall. A lawn is one thing. A driveway, a pool deck, or a structure near the top of the slope is a surcharge load, and the wall has to be designed for it. This is one of the most commonly missed items on a cheap estimate.

Permitting. Review can involve FDEP, the U.S. Army Corps of Engineers, the St. Johns River Water Management District and your county or city building department. Requirements vary by site and are revised periodically — confirm current requirements with the reviewing agency. We handle the permitting on the projects we build, and the permit timeline is normally the longest item on the schedule.

How we build

1. Mobilization and protection. Equipment access is planned around your property. On tight residential lots this is a real constraint and sometimes decides the construction method.
2. Driving the sheet piles. The piles are driven to design embedment, panel by panel, with the interlocks engaged so the wall acts as a continuous structure rather than a row of separate boards. Alignment is held as the wall advances — a wall that wanders is a wall that will have joint problems.
3. Tiebacks and anchors. Tieback rods are installed through the wall and run back to deadman anchors set in undisturbed soil at a depth and distance that puts them outside the active soil wedge. Getting the anchor placement wrong is a quiet failure: the wall looks finished and the tiebacks do nothing.
4. The cap. The concrete cap ties the tops of the piles together, distributes load along the wall, and gives you the finished edge you actually walk on. It is formed, reinforced and poured as a structural element.
5. Backfill and drainage. Backfill is placed and compacted in lifts. Filter fabric and a drainage detail at the joints let water out without taking soil with it — this single detail is the difference between a wall that holds your yard and a wall that slowly exports it.
6. Finish and cleanup. Grading, restoration of the disturbed area, and a walkthrough.

Material choice at the construction stage

New construction is where you get a free choice of material, which is not true of a repair. The three we build in:

• Vinyl sheet pile — the default for most residential First Coast shorelines. Will not rot or corrode, and the tieback system does the structural work.
• Concrete — the heaviest and longest-lived option, and the usual choice where the wall also serves as a finished architectural edge or where loads are high.
• Wood — treated timber, lowest initial cost, and the right call when you are matching an existing structure or working a sheltered location on a tighter budget.

The cost page explains how those choices move the estimate.

If you have an existing wall

Not every property that asks for new construction needs it. If you have a wall that is failing, start with bulkhead repair and bulkhead replacement — the second one covers how we decide between the two. A marine inspection gives you that answer in writing, with the condition of the elements you cannot see from the top.
