Seawalls · Lake Michigan Shoreline

Seawalls built to hold Lake Michigan back.

Steel, vinyl, and stone revetment seawalls engineered for the highest-energy shoreline in the Midwest — protecting lakefront homes from St. Joseph through New Buffalo and across the inland lakes of SW Michigan since 2015.

What we do

Materials we build with.

A seawall is the most consequential build on your property. Get it wrong and you'll lose 6 feet of yard a winter. Get it right and your great-grandchildren will inherit the same shoreline you bought. We build with three primary systems depending on water depth, wave energy, and your site's elevation: steel, vinyl, and stone revetment.

Every seawall project starts with a site survey, an EGLE permit application, and a written engineered plan that accounts for ice push, wave height, and the unique challenges of Lake Michigan's southern shore. Our crews handle excavation, sheet driving, tieback installation, capping, and the backfill grading that turns a wall into a yard.

Steel Sheet Pile

The standard for Lake Michigan's open-coast properties. Z-profile steel sheets driven to refusal, with concrete cap and tieback anchors. Engineered for 50+ year service life.

Vinyl Sheet Pile

Lighter, more cost-efficient, and ideal for inland lakes and lower-energy bays. Won't corrode and matches well with composite caps.

Stone Revetment

Boulders placed at engineered angles to absorb wave energy. The right call for slope-protected shorelines and projects where aesthetics matter as much as function.

How we work

Clear process. No surprises.

Free site visit. Engineered, line-item quote. In-house crew. Yearly check-ups.

Shoreline Survey

We measure your bluff, water depth, and recent erosion. We also pull historic aerials so you can see exactly how much shoreline has moved over the past decade.

Engineered Design

Full structural design with EGLE permit application, riparian rights documentation, and contractor's bond — all submitted on your behalf.

Build Phase

Sheet driving, tieback installation, concrete cap pour, and backfill grading. Most residential walls take 2–4 weeks of on-site work.

Long-Term Service

We come back yearly for inspection. Tiebacks tighten, gaps fill, and you get documentation for your insurance carrier.

Frequently asked

Questions homeowners ask us.

How much does a seawall cost on Lake Michigan?

Most steel seawall installations on Lake Michigan run $700–$1,400 per linear foot installed, depending on bluff height, water depth, and tieback requirements. Vinyl seawalls on inland lakes run $400–$700 per foot. Stone revetment varies based on stone source and slope geometry.

Do I need a permit for a seawall in Michigan?

Yes — every seawall on Lake Michigan and most inland lakes requires a Joint Permit Application through EGLE and the U.S. Army Corps of Engineers. We handle the entire permit process, typically a 60–120 day turnaround.

How long does a steel seawall last?

Properly installed and maintained Z-profile steel seawalls on Lake Michigan have a 50–75 year design life. Annual inspection and timely tieback adjustments extend that further. Vinyl walls on inland lakes typically last 50+ years with no corrosion concerns.

Can you replace an existing failed seawall?

Yes — we handle full seawall replacement projects, including removal of failed timber, concrete, or steel walls. We also evaluate and repair partially failed walls when full replacement isn't yet warranted.
