Stop Shoreline Erosion with a New Seawall
Complete seawall replacement services for waterfront properties experiencing erosion and structural failure in Merritt Island, Florida.
When you notice cracks running through your seawall, soil washing out behind it, or the structure leaning toward the water, the wall is no longer protecting your property from erosion and tidal pressure. A failing seawall can lead to land loss, sinkholes near the waterline, and damage to docks or structures built close to the shore in Merritt Island. Precision Docks & Seawalls replaces deteriorating seawalls in Merritt Island using modern materials and proper anchoring systems designed to withstand tides, waves, and the weight of saturated soil pressing against the wall.
Seawall replacement involves removing the old structure, excavating the area, and installing a new wall with tie-backs or deadman anchors that extend inland to hold the wall in place. The new seawall is built using vinyl sheet piling, concrete panels, or reinforced masonry, depending on your property's conditions and your preferences. We assess the height of your wall based on tidal range, evaluate soil stability, and apply for permits before beginning work. Replacing a seawall is a significant project that typically takes one to two weeks, depending on access and weather.
If your seawall is showing signs of failure and you want to stop erosion before it worsens, contact Precision Docks & Seawalls in Merritt Island to schedule an inspection and review replacement options.
What Replacing Your Seawall Accomplishes
After a seawall is replaced at your Merritt Island property, the shoreline stops retreating and the soil behind the wall remains stable without washing into the water. The new wall stands straight and is anchored securely with tie-back rods buried several feet inland, which prevents the structure from leaning forward under pressure from saturated soil. We backfill the area with clean fill and gravel to improve drainage, and we grade the surface so rainwater flows away from the wall instead of pooling behind it.
Once the replacement is finished, you will notice that the ground near the waterline feels solid underfoot and no longer sags or forms voids. Structural stability is restored with modern materials and proper anchoring systems to ensure long-term strength and reliability. You may also see improved appearance and property value, as a new seawall gives the waterfront a cleaner and more maintained look compared to a cracked or leaning structure.
We use materials designed to last decades in marine environments, including vinyl sheet piling that resists corrosion and cracking, and concrete panels reinforced with rebar and treated for saltwater exposure. The anchors are installed at a depth and angle calculated to handle soil pressure and wave loads specific to your property. Seawall replacement provides a lasting solution designed to withstand tides, waves, and harsh marine conditions. This service does not include dock repair or upland grading beyond what is needed to support the new wall.
Concerns We Address Before Starting Work
Homeowners considering seawall replacement often ask how long the project takes, what permits are required, and whether the work will disrupt access to their dock or waterfront in Merritt Island.
What are the signs that my seawall needs to be replaced?
You should replace your seawall if you see cracks wider than a quarter inch, soil washing out behind the wall, the wall leaning or bulging, or sinkholes forming near the waterline. Erosion protection becomes ineffective once these issues develop, and delaying replacement can lead to land loss.
How long does a seawall replacement take?
Most residential seawall replacements take one to two weeks, depending on the length of the wall, access for equipment, and weather conditions. We schedule the work around tides to ensure safe access and proper installation of the anchors.
What material should I choose for my new seawall?
Vinyl sheet piling is the most common choice because it resists corrosion and lasts thirty years or more. Concrete is heavier and more durable in areas with strong wave action, while timber is less expensive but requires more maintenance and has a shorter lifespan.
How do you anchor the new seawall?
We install tie-back rods that extend from the wall inland to a buried deadman anchor or helical pier. The anchors are positioned at a depth and distance calculated to hold the wall against soil pressure and tidal forces.
What permits are required for seawall replacement in Merritt Island?
Most seawall replacements require permits from the Florida Department of Environmental Protection and your local county or city. We handle the permit applications and inspections, and we design the wall to meet setback and height requirements.
