7 Signs Your Bulkhead Is Failing (and When to Replace It)

The short answer

The biggest signs of a failing bulkhead are a wall that leans or bows toward the water, sinkholes or low spots in the yard behind it, and soil or sand washing through the wall at low tide. Also watch for a rotted or cracked cap, rusted hardware, gaps between sheets, and water coming over the top at high tide. One isolated problem can often be repaired; several usually mean replacement.

What are the warning signs of a failing bulkhead?

Walk your wall at dead-low tide, when the most of it is exposed, and look for:

• Leaning or bowing — the top of the wall tipping toward the water usually means failing tie-backs.
• Sinkholes or depressions behind the wall — soil is escaping underneath or through it.
• Soil washing out at low tide — sand or mud visible on the bottom in front of the wall.
• Gaps or separated sheets — open seams let backfill wash out with every tide.
• Rotted, cracked, or loose cap and whalers — the members that tie the wall together.
• Rust stains and corroded hardware — tie-rods and bolts losing their grip.
• Water over the top at high tide — the wall is too low for today’s flooding (see bulkhead height requirements).

Should I repair or replace my bulkhead?

If the problem is local — one washout, a single broken tie-back, a section of rotted cap — a repair can be the smart move. If the wall is leaning along its length, losing soil in several places, or is well past its expected life (vinyl vs. timber lifespans), repairs usually just delay the inevitable. We’ll tell you honestly which one your wall needs.

Also check your town’s rules: in Margate, repairs of $10,000 or more trigger the minimum-elevation requirement, which can make replacement the better value.

What happens if I wait?

A failing bulkhead rarely fixes itself. Every tide pulls more soil out from behind it, the yard settles, and a nor’easter can turn a repairable wall into an emergency. Catching it early keeps your options — and your costs — down. Here’s what a new bulkhead typically costs.

Common questions

Why is my yard sinking behind my bulkhead?

Sinkholes behind a bulkhead almost always mean soil is escaping through gaps in the wall or under its toe. It should be looked at before it spreads.

Why is my bulkhead leaning?

Leaning usually means the tie-backs (deadmen) that anchor the wall have failed or the soil pressure has overwhelmed them.
