Piling Wrap Installation

Timber pilings are constantly exposed to saltwater, marine growth, tidal movement, and wood-boring organisms. Once deterioration begins, the remaining service life of a piling can fall quickly.

Fixt Marine installs heavy-duty HDPE piling wrap systems on new and existing timber pilings. The wrap forms a physical barrier around the vulnerable submerged and tidal zones of the piling, helping protect the wood from marine borers and continued exposure.

We provide piling wrap installation for docks, piers, marinas, marine facilities, and waterfront structures throughout Mobile Bay and the Gulf Coast.

Send us the number of pilings, approximate diameters, required wrap lengths, water depth, and project location for a quote.

What piling wrap does

Piling wrap creates a durable plastic barrier between the timber and the surrounding marine environment.

When correctly sized and installed, piling wrap can:

• Protect new timber pilings from marine-borer attack
• Help slow further deterioration of serviceable existing pilings
• Cover the submerged, tidal, and splash zones
• Reduce direct exposure to saltwater and marine growth
• Extend the useful life of a dock or marine structure
• Reduce the likelihood of premature piling replacement
• Provide a cost-effective preventive-maintenance option

Piling wrap protects the wood that is still present. It does not replace structural material already lost to rot, marine borers, cracking, or physical damage.

New piling protection

The best time to wrap a timber piling is when it is new.

Pressure-treated timber is still vulnerable to marine organisms, especially after surface damage, checking, drilling, cutting, or long-term exposure. Installing wrap early protects the vulnerable portion of the piling before significant deterioration develops.

Fixt Marine can coordinate with dock builders and marine contractors to install piling wrap during new construction or immediately after the pilings are driven.

New-piling wrap is appropriate for:

• Residential docks
• Commercial piers
• Marinas
• Boat slips
• Boathouses
• Boardwalks
• Fishing piers
• Industrial waterfront structures
• Fender and guide pilings

Wrapping existing pilings

Existing timber pilings can often be wrapped if they still have sufficient structural capacity.

Before installation, Fixt Marine cleans the piling and evaluates the accessible surface for visible deterioration, section loss, cracking, soft wood, and marine-borer damage. Heavy growth must be removed so the wrap fits properly against the piling.

If the piling remains structurally serviceable, wrap may help protect it from continued exposure. If substantial wood has already been lost, a structural jacket or replacement may be the better solution.

An engineer may be required when the remaining capacity of the piling is uncertain or when the structure carries significant loads.

Piling wrap versus structural piling repair

These systems solve different problems.

• New timber piling: preventive HDPE piling wrap
• Existing piling with little deterioration: clean, inspect, and wrap
• Loose or damaged existing wrap: repair or replace the wrap
• Moderate damage with adequate remaining core: evaluate for a structural jacket
• Significant section loss or structural weakness: SnapJacket, engineered repair, or replacement
• Broken, displaced, or severely deteriorated piling: structural evaluation and likely replacement

A plastic wrap should not be presented as a structural repair. If the piling has already lost meaningful strength, simply covering it will hide the damage without correcting it.

For structural damage, see our piling repair and rehabilitation services.

Piling wrap materials

Fixt Marine uses durable plastic piling-wrap material selected for continuous marine exposure.

The final material and fastening system depend on:

• Piling diameter
• Required wrap length
• Saltwater or brackish-water exposure
• Tidal range
• Current and wave action
• Existing piling condition
• Project specifications
• Engineer or manufacturer requirements

Wrap sections are sized to provide sufficient overlap and full coverage of the required protection zone.

How much of the piling should be wrapped?

The correct wrap length depends on the site, tidal range, bottom elevation, piling condition, and marine-borer exposure.

Wrapping only the visible waterline can leave the lower portion of the piling unprotected. In many applications, the wrap should extend from below the mudline to above the normal high-water or splash zone.

Fixt Marine evaluates the required coverage before ordering material. If actual piling lengths, bottom elevations, or site conditions differ from the information provided, the scope and price may require adjustment.

Piling wrap inspections and repairs

Existing piling wrap should be inspected periodically, especially after storms, vessel impacts, construction activity, or changes in the dock structure.

Common problems include:

• Loose overlaps
• Missing or corroded fasteners
• Torn or punctured material
• Wrap pulled above the mudline
• Storm or impact damage
• Gaps around irregular pilings
• Marine growth hiding damaged areas
• Improperly sized previous installations

Fixt Marine can inspect existing systems, replace damaged sections, add fasteners, and rewrap pilings when necessary.

Who we serve

Dock and waterfront property owners

We install protective wrap on residential docks, fishing piers, boathouses, and other privately owned waterfront structures.

Marinas and boatyards

Fixt Marine can wrap slip pilings, dock-support pilings, guide pilings, and other timber components while coordinating around marina traffic and occupied slips.

Marine construction contractors

We provide subcontract piling-wrap installation for new dock construction, piling replacement, and waterfront improvement projects.

Ports, terminals, and commercial facilities

Our divers install and repair wrap on timber pilings used in commercial piers, fleeting facilities, fender systems, and marine terminals.

Municipalities and public agencies

We support piling-protection projects for public docks, boardwalks, boat launches, fishing piers, parks, and waterfront infrastructure.

Engineers and property managers

Fixt Marine can provide field measurements, accessible-condition observations, installation documentation, and contractor support for planned piling-protection work.

Why wrap pilings before they fail?

Piling replacement is disruptive and expensive. It may require a barge, crane, pile-driving equipment, demolition, and partial removal of the dock structure.

Preventive wrapping is normally far less involved than replacing damaged pilings. The strongest case for piling wrap is not rescuing a severely deteriorated piling. It is protecting a new or serviceable piling before structural damage develops.

Waiting until the piling becomes soft, hollow, or visibly reduced in diameter limits the available repair options and increases the eventual cost.
