Maritime Timber Conservation, Pier Infrastructure Audits, and Pile Inspections

We survey wooden piers for biological decay, assess the load-bearing stability of waterfront retaining walls, and deliver engineering reports for marine-grade timber structures along temperate coastlines.

Why choose us

Measurable outcomes for coastal infrastructure

Every inspection and audit delivers a clear, actionable result that protects your asset and budget.

Early decay detection

Acoustic tomography and core sampling identify internal rot and marine borer damage before visible signs appear, reducing emergency repair costs by up to 40%.

Load rating certainty

Finite element models calibrated with field data give you a precise load capacity for each pile and beam, so you can safely extend service life without guesswork.

Corrosion risk mapping

Ultrasonic and radiographic surveys of steel-to-timber connections pinpoint crevice corrosion hotspots, enabling targeted retrofits rather than wholesale replacement.

Regulatory compliance

Our audit reports meet ASCE, PIANC, and local port authority standards, giving you a defensible record for insurance and permitting renewals.

Prescription‑grade treatment plans

We don’t just flag problems — we specify the preservative, the application method, and the monitoring schedule for each timber condition found.

Lifecycle cost transparency

A clear breakdown of repair vs. replace scenarios, with projected maintenance intervals, helps you allocate capital with confidence.

Ready to Schedule a Pier Survey?

We coordinate directly with marina operators and port engineers. A single site walkthrough identifies the most critical timber zones for core sampling and load analysis.

No obligation — we provide a scope letter and estimated timeline after the initial visit.

Why Coastal Engineers Choose Our Approach

Our inspection methodology is built on direct field data, not generic assumptions. We explain the reasoning behind each assessment so clients can make informed repair decisions.

Biological Decay Mapping

We identify and map marine borer species — Limnoria, Teredo navalis, and others — using underwater video and core sampling. This distinguishes active infestation from old damage and guides treatment priority.

Load-Bearing Verification

Rather than relying on visual condition alone, we combine increment core data with finite element modeling. This quantifies remaining capacity and identifies critical sections before failure occurs.

Connection Corrosion Audits

Steel-to-timber connections in saltwater environments are inspected using ultrasonic thickness gauging and radiographic imaging. We document crevice corrosion patterns and recommend retrofit materials such as stainless steel or polymer encapsulation.

Trusted by municipal port authorities and private marina operators along the Pacific and Gulf coasts for independent, data-driven timber assessments.

Frequently Asked Questions

What causes timber decay in marine piers?

The primary agents are marine borers like Limnoria and Teredo navalis, which tunnel into wood below the waterline. Fungal rot also occurs in the splash zone where moisture and oxygen are both present. Regular underwater inspections are essential to catch damage before it compromises load-bearing capacity.

How often should a wooden pier be inspected?

We recommend a comprehensive survey every two to three years for structures in temperate saltwater. Piers in warmer or heavily polluted waters may need annual checks. The interval also depends on the timber species, connection type, and previous treatment history.

What methods do you use for pile inspection?

We combine visual surveys above and below the waterline with acoustic sounding, increment core sampling, and ultrasonic thickness gauging. For deeper assessment, we apply finite element modeling calibrated to core data. The choice of method depends on the pile material, access constraints, and the suspected damage type.

Can you assess steel-to-timber connections underwater?

Yes. We use ultrasonic thickness gauging and radiographic imaging to detect crevice corrosion at bolted connections. The inspection covers the condition of the steel plate, bolt shank, and the surrounding timber for signs of galvanic or chemical degradation.

Do you provide a report with repair recommendations?

Every inspection concludes with a detailed engineering report that includes condition ratings, decay maps, load capacity estimates, and prioritized repair options. We do not prescribe a single solution; instead we present the tradeoffs between replacement, encapsulation, cathodic protection, or stainless steel retrofits.
