Capabilities · Sheet Piling
Sheet Piling
Interlocking steel sheets driven or vibrated into the ground, giving retention and a groundwater cut-off in one system. In saturated Florida sand that combination is often exactly what the job needs.

Where sheets will not go
Sheet piling is efficient and fast when the ground cooperates. It stops cooperating in two conditions that are common here: cemented layers or coquina rock that will not let a sheet through, and sites where vibration is unacceptable because of what is next door. Either condition rules the method out, and finding that at mobilization is expensive.
When sheets are the right call
- Saturated granular soil where a cut-off is worth as much as the retention.
- Depths where a cantilever or a single line of bracing will do.
- Sites with room to drive and to extract afterwards.
- Temporary works, where recovering the steel changes the economics.
- Waterfront and seawall work, where cut-off is the point.
How we handle it
- 01Check the borings for refusal layers before committing to the method.
- 02Assess vibration exposure for adjacent structures.
- 03Select driven or vibratory installation for the setting.
- 04Design bracing or tiebacks where cantilever will not hold.
- 05Monitor movement and vibration through installation.
- 06Extract and make good, or cut off and leave, per the design.
Being able to pull the sheets afterwards is a real part of the cost case on temporary works. On a site where extraction is impossible because of what has been built against them, that saving disappears and the comparison against other methods changes. Work it out at design stage, not at demobilization.
Said plainly
Where we stop
If the borings show refusal or the neighbor cannot take vibration, we will say sheets are the wrong method rather than mobilize a rig and find out.
FAQ
Common questions
- Are sheets removed afterwards?
- On temporary works usually yes, and the recovery is part of the cost case. Sometimes access makes it impossible — decide at design.
- How noisy is it?
- Vibratory installation is significant. On a sensitive site that alone can rule the method out.
- Do sheets stop water?
- The interlocks give a substantial cut-off. Not perfectly watertight, but often enough to change the dewatering design.
- What if we hit rock?
- Sheets refuse. That is why the borings are read before the method is chosen.
Ground conditions
Saturated Sand
The most common condition across coastal Florida: clean permeable sand with the water table a few feet down. It excavates easily and it will not stand up wet.

Coquina & Cap Rock
Cemented shell and limestone layers turn up across Florida at unpredictable depths, and they are the reason a method chosen from experience rather than borings goes wrong.

Organic Muck & Peat
Organic soils turn up across inland and former wetland Florida. They compress under load, keep compressing for years, and cannot be improved by compaction.

Tidal & Waterfront Sites
Near the Intracoastal and the coast, the groundwater is tidally connected. It rises and falls twice a day, and a dewatering system designed for a static table will fail on the flood.

Karst & Sinkhole Risk
Much of central Florida sits on limestone that groundwater has dissolved over time, leaving voids and raveling zones. It is the one condition where the investigation matters more than the design.

Uncontrolled Fill
Older Florida sites are frequently built on fill placed decades ago with no compaction record and no control over what went in. It may be excellent or it may contain a buried structure.

Construction Dewatering
In most of coastal Florida the groundwater sits a few feet below grade. Any excavation deeper than that is an excavation in water until something is done about it, and what gets done determines the program.

Support of Excavation
Support of excavation is the system that keeps the hole open and keeps the ground next to it from moving. On a tight urban site it is the whole job.

Secant & Slurry Walls
Overlapping drilled piles, or a trench supported by slurry and filled with concrete, forming a structural wall that also cuts off groundwater. The answer where sheets will not go.
