Preserving and Stabilizing Seawalls on Marco Island

Nestled along the Southwest Florida Coast, Marco Island stands as a captivating blend of culture and nature. Here, the shimmering Gulf of Mexico embraces pristine white-sand beaches, while its waterfront invites exploration with its array of culinary treasures and charming shops. Nearby, the islands of Everglades City and Goodland beckon with opportunities for further day-trip escapades.

Marco Island Seawalls

Seawalls play a crucial yet often overlooked role in protecting Marco Island waterfront properties from hurricanes and storm surges. As these vital structures approach the 35 to 45-year mark, they face the inevitable effects of time. Constant exposure to saltwater and the gradual decay of concrete jeopardize their stability and effectiveness. To safeguard your property and maintain the integrity of your seawall, proactive maintenance and repair are essential. Our expert team specializes in extending the lifespan of seawalls, ensuring they continue to serve as your frontline defense against nature’s relentless forces.

Warning Signs of Seawall Damage

Despite the prevailing belief among waterfront property owners that their seawalls are prone to damage, the reality is far more sobering. The erosion of seawalls often begins subtly, with no overt signs of deterioration. Yet, beneath the surface, soil and sand are gradually swept away, creating erosion that weakens the seawall’s ability to withstand the onslaught of king tides, storm surges, and hurricanes, leaving properties vulnerable to devastation.

Seawall Soil Erosion

Seawall soil erosion refers to the gradual loss of soil behind seawalls, primarily caused by the corrosive effects of saltwater and the sinking of seawalls over time. In Florida, where much of the coastline is reclaimed swamp land, seawalls are built to protect waterfront properties and canals. However, as these seawalls settle, the seams between concrete panels may open, allowing soil to escape into the canal or Gulf of Mexico.

As soil erodes from behind the seawall, sinkholes, or cavities form, weakening the structural integrity of the seawall. This erosion process can lead to cracks in the seawall cap, exacerbating the problem. Daily tidal changes, as well as waves and storms, further contribute to the wear and tear on aging seawalls.

Hydrostatic Pressure

Hydrostatic pressure is generated by the weight of standing water behind the seawall, presenting a significant threat to coastal structures. When weep holes fail to function properly, excess water pressure builds up, exerting force on the concrete seawalls, captains’ walks, retaining walls, and surrounding landscaping.

Weep Holes Purpose

Weepholes are designed to alleviate seawall pressure by allowing water to escape behind the panels. However, these openings can become blocked by debris such as marine barnacles and mangrove seeds, hindering water flow, and increasing the risk of damage to the seawall structure.

Seawall Repair Solutions

Seawall Savers employs a sophisticated, exclusive repair system called “Seawall Seam Systems.” This system features a plastic brace strategically positioned at the seams of seawall panels, effectively sealing the vertical joints to prevent erosion loss on the upland side. The brace is securely attached to the concrete seawall using specialized 316 grade stainless steel fasteners. By installing this brace, Seawall Savers effectively eliminates the formation of sinkholes and cavities behind your seawall, bolstering its structural integrity.

Filter Systems

Furthermore, when the existing weepholes—essential for relieving hydrostatic pressure on the landward side of the wall—are obstructed and non-functional, it’s imperative to address this issue. Seawall Savers implements “Jet Filters” in each concrete panel to insure proper drainage. These filters efficiently alleviate hydrostatic pressure buildup behind the seawall, ensuring optimal performance and longevity.

Seawall Evaluations

Regular assessments of your Marco Island seawall are essential to identify potential issues before they escalate into catastrophic failures. These assessments provide crucial insights into the structural integrity of the seawall, allowing property owners to take proactive measures to address any weaknesses. Employing advanced repair materials and techniques, such as ABS Plastic products and marine helical tie-back anchoring systems, can reinforce seawalls against hydrostatic pressure and corrosion, ensuring their long-term durability and stability.

Seawall Alert Signs

Regularly check for vegetation growth on the seawall, especially around the weepholes.

• Clear the weep holes regularly to reduce hydrostatic pressure.

• Conduct detailed inspections for even the smallest cracks in the concrete.

• Leaning seawalls towards the water may indicate issues with the tieback system.

• Slabs leaning towards the land might suggest the seawall’s base is tilting outward.
