Bulkheads vs. Seawalls
In everyday use, "bulkhead" and "seawall" often mean the same thing. When people make a distinction, bulkheads usually refer to retaining walls in calmer water — canals, lakes and marinas — while seawalls face more wave energy.
Bulkheads can be built from concrete, vinyl, steel or treated timber. Timber bulkheads, still found on some older properties and lakefronts, have their own set of problems like rot and marine borers.
Common Bulkhead Problems
Rotting or split timber
Wood bulkheads eventually lose strength, especially at the waterline.
Bowing sheet piles
Vinyl and steel walls can bow outward when anchoring weakens.
Washout at joints
Soil escaping between sheets or panels, leading to sinkholes.
Corroded hardware
Rusted tie rods, walers and bolts.
Bulkhead Repair Options
Section replacement
Replacing failed sections of sheeting or timber.
Waler and tie rod replacement
Restoring the hardware that holds the wall in place.
Void filling and sealing
Stopping soil loss behind the wall. See seawall erosion repair.
New cap
Adding or replacing a cap to tie the system together.

Repair or Rebuild?
Localized damage can often be repaired. If the wall is failing along much of its length, or an old timber bulkhead is past its prime, a new wall may be more cost-effective long-term. Our guide on seawall repair vs. replacement covers the same decision factors.
Bulkheads Across South Florida
Inland canals, lakes and marina basins across Broward, Miami-Dade and Palm Beach counties are lined with bulkheads of every age and material. Many were built decades ago and are aging in parallel.

Bulkhead Repair FAQs
Is a bulkhead the same as a seawall?
Often, yes — the terms are used interchangeably. Some people use "bulkhead" specifically for walls in calmer waters.
How long does a timber bulkhead last?
It depends on the wood treatment, water conditions and maintenance. Timber generally has a shorter service life than concrete or vinyl in South Florida's climate.
Can I replace a wood bulkhead with vinyl or concrete?
Frequently, yes, subject to engineering and permitting.
