Seawall Repair in Marathon.

Marathon sits mid-chain, with water on every side of the problem.

Between the Gulf-side flats and the Atlantic, a middle Keys city is built around its canals and harbors.

Marathon is a city spread across a string of keys that includes Vaca Key, Fat Deer Key, and Boot Key, among others, with the Seven Mile Bridge marking its western end. A large share of its homes sit on dredged residential canals, and the city also has working waterfront: marinas, boat yards, and commercial docks where bulkheads carry heavy loads every day.

That mix matters for repair. A residential canal wall is mostly holding back soil and a lawn, while a commercial bulkhead may carry vehicles, lifts, and stored equipment. The same crack can mean something very different in each case, and the repair has to be engineered for what the wall actually supports.

The City of Marathon is an incorporated city, so seawall and bulkhead permits are generally reviewed by the City instead of by Monroe County. Environmental review at the state and federal level can also apply to work at or below the mean high-water line. The Keys are an Area of Critical State Concern, and the City operates its own growth and permit framework within it, so we confirm the pathway for each scope up front.

Souffront prepares the drawings and manages the permitting, then schedules the work around the approvals. For heavier structures a full rebuild may be justified, which we price through seawall construction.

Marathon repair scope, from diagnosis to closeout.

Fixed-fee, line-itemed, and tied to the engineer's findings.

• Engineer assessment of the seawall or bulkhead and its backfill
• Load review for walls carrying vehicles, lifts, or structures
• Sealed repair design and permit drawings
• Cap reconstruction and concrete spall repair
• Panel and sheet stabilization, joint sealing
• Tieback, whaler, and anchor replacement
• Grout and fill to restore ground lost behind the wall
• Permit submittals to the City and environmental agencies
• Work phasing for occupied or operating waterfront
• Final inspections and closeout documentation

Marinas, canal homes, and condo docks cannot simply stop for a month.

Many Marathon jobs involve a property that must stay in use. A marina has boats to move, a condo has residents to access their slips, and a home has a family living beside the work. We plan the sequence, the staging, and the working hours with that in mind, and we describe them in the proposal rather than leaving them to be negotiated later.

Hurricane preparation shapes the calendar as well. We try to schedule the structural work outside the peak of the season where the repair allows it, and we design the details to handle surge and wave action. The overview of how a project runs is on our seawall repair page.
