Seawall Construction & Repair Services
Speeler Gibson Marine builds, repairs, and replaces seawalls across Tampa Bay and Sarasota County using high-performance vinyl and composite sheet piling backed by a 50-year warranty. Whether your wall is cracking, leaning, or you’re building new, we handle engineering, permitting, and construction from start to finish.
Our dedication is preferred by homeowners, trusted by contractors and developers, and sets industry standards. Speeler Gibson Marine Construction specializes in superior seawall construction, using only the industry’s leading products. Construction of a seawall requires quality materials and advanced technology in order to prevent erosion and to withstand strong winds and high waves. A seawall, also known as a bulkhead or retaining wall, keeps the water from eroding the soil back into the water. Each seawall project has its own set of unique requirements. The stability of any seawall is dependent upon variables such as wall height, sheet pile length and strength, wale system, backfill, foundation soil and tide.
Homeowners and developers are looking at new ways to protect their properties due to the frequency of storms and hurricanes. The challenges of owning waterfront property include storm surges causing erosion, UV damage to traditional materials, corrosion of aluminum and steel, and deterioration caused by marine borers that thrive on pressure-treated lumber. Our design team will work with you from start to finish on designing and constructing your seawall in order to protect your most valuable investment. Our standard is using top-quality products and exceptional design to ensure we meet each job’s unique challenges.
We use the highest performance vinyl and composite sheet piling backed with a 50-year warranty. Our product’s warranty guarantees against rust, rot, corrosion, falling prey to marine borers, or UV damage from the sun. Because commercial marinas or waterfront residences may require a seawall made of stone (rip rap), concrete, or treated specialty wood, we can accommodate according to your specific needs.
Preventative vs Reactive
Neglecting to maintain a seawall could result in property damage, loss of land, and decreased property value. Regular repairs, maintenance, and reinforcement of a seawall ensure a longer lifespan and can eliminate the need for costly emergency repair or replacement. Repairing an existing seawall can also incorporate new technologies, materials, and construction methods that offer better protection against damage. A properly functioning seawall can reduce erosion, protect marine wildlife, and help preserve the natural beauty of a shoreline.

New Seawall Construction, Repair & Replacement
Whether you need a brand-new seawall, a repair to stop active damage, or a full replacement of a failing wall, our crews handle it end to end. We restore caps and tie-backs, fix washouts and sinkholes behind the wall, reinforce leaning panels, and — when repair no longer makes sense — replace the wall with new vinyl or composite sheet piling engineered for your shoreline. Every job starts with a free on-site inspection so you only pay for what your wall actually needs.

Warning Signs Your Seawall Is Failing
Catch these early and a repair may be all you need:
- Cracks or pitting on the wall face or cap
- Leaning, bowing, or separated panels
- Rust stains bleeding through the surface
- Sinkholes, soft spots, or soil washing out behind the wall
- Standing water or new low spots near the wall after rain
If you see any of these, book a free inspection — small repairs cost far less than a full replacement.
