Your shoreline is one of the most valuable parts of your property, and a properly built bulkhead protects it from erosion, flooding, and damage. Choosing between wood and steel bulkheads comes down to cost, durability, maintenance, and how much yard disruption you’re willing to tolerate. Understanding the differences can help you make an informed decision and ensure your waterfront looks great and stands strong for years to come.

1️⃣ Why Quality Matters
Not all bulkheads are built the same. Proper installation—including the right depth for pilings or sheathing, strong tiebacks, and high-quality materials—is crucial for long-term performance. Cutting corners can lead to collapsed yards, silt leaks, and early replacement.
2️⃣ Wood Bulkhead Highlights
-
Budget-friendly: Lower upfront cost.
-
Traditional look: Complements natural waterfront settings.
-
Maintenance needed: Lifespan ~20 years, prone to rot.
3️⃣ Steel Bulkhead Highlights
-
Durable & long-lasting: Lifespan ~40 years.
-
Minimal yard disruption: Most construction happens from the water side.
-
Low maintenance: Resistant to decay; no filter fabric needed.

Protecting your shoreline is more than just aesthetics—it’s about durability, safety, and long-term value. When it comes to bulkheads, homeowners typically have two main options: wood or steel. Both materials have unique advantages and considerations, and understanding the differences can help you make the best decision for your property.
Wood Bulkheads
How They’re Built:
Wood bulkheads are typically constructed or replaced in sections:
-
6×6 pilings are driven 4.5’–5’ apart, about 3’ into the lakebed.
-
Whaler boards (horizontal) are installed behind the pilings, followed by sheathing boards (vertical).
-
Filter fabric is laid behind the boards and dug 1’ below the lakebed.
-
Excavated lake soil is used to refill the cavity.
-
Deadman posts or sucker rods hold the bulkhead in place, set 10’ back and tied to each piling.
-
The bulkhead is finished with a cap board on top.
Pros:
-
Lower upfront cost, making wood an attractive, budget-friendly option.
Cons:
-
Short lifespan (~20 years).
-
Wood is prone to rot and wear over time.
-
Requires deadman posts, which tear up 10’–15’ of your yard.
Common Shortcuts to Watch For:
-
Shallow placement of filter fabric, leading to silt leaks and collapsing yards.
-
Pilings and sheathing not set deep enough, reducing structural strength.
-
Using cable instead of sucker rods for tiebacks.
-
Failing to remove old wood bulkheads or properly install filter cloth.
Steel Bulkheads
How They’re Built:
Steel bulkheads offer a modern alternative and can be installed over an existing bulkhead or from scratch:
-
I-beams span across the bulkhead to keep the structure straight.
-
Sheathing boards hook together for a near-watertight fit—no filter fabric required.
-
Boards are driven until point of refusal, which can be 3’–10’ or more, depending on soil conditions.
-
Sheathing is welded to the I-beam.
-
Sucker rod tiebacks replace deadman posts, preserving your yard.
-
Finished with angle iron over the top cap for a clean, professional look.
Pros:
-
Long-lasting (~40 years).
-
Minimal yard disruption—most work is done from the water side.
-
Resistant to decay and extremely durable.
Cons:
-
Higher initial cost than wood.
Common Shortcuts to Watch For:
-
Using low-quality steel.
-
Failing to drive sheathing deep enough into the ground.
Side-by-Side Comparison
| Feature | Wood Bulkhead | Steel Bulkhead |
|---|---|---|
| Lifespan | ~20 years | ~40 years |
| Yard Impact | Requires deadman posts, tears up yard | Tiebacks only, minimal disruption |
| Durability | Prone to rot and wear | Resistant & strong |
| Installation | Onshore + underwater | Mostly from water side, I-beams keep wall straight |
| Maintenance / Filter | Filter fabric required | No filter needed, watertight |
| Cost | Lower upfront cost | Higher upfront cost |
| Common Issues | Silt leaks, weak tiebacks, old wood left behind | Shallow sheathing, low-quality steel |
| Best Use | Budget-friendly, okay with future replacement | Long-term durability, low maintenance |
Which Bulkhead is Right for You?
-
Wood: Choose wood if cost is the priority and you’re okay with a shorter lifespan.
-
Steel: Choose steel for durability, minimal yard disruption, and low maintenance over decades.
Tip: Whatever you choose, make sure your contractor follows best practices—proper depth, strong tiebacks, and high-quality materials—so your bulkhead will last for years to come.
