A Comprehensive Marina Seawall Erosion Repair Case Study: Tackling Erosion and Enhancing Coastal Protection
Learn how Seawall Savers conducted a seawall erosion repair in Naples, Florida, Pelican Isle Marina with targeted foam grouting. Discover the project’s challenges and results.
Pelican Isle Yacht Club encountered critical seawall problems like cavities and voids along its perimeter. It led to uneven settling of access pavers, creating liability and maintenance concerns. Additionally, stormwater outfall pipes were suffering from soil erosion, with four 24” pipes. It required urgent sealing to prevent further damage.
Seawall erosion poses a significant threat to coastal infrastructure, risking both property damage and safety. At Pelican Isle Yacht Club in Naples, FL, severe erosion challenges demanded an expert approach. This case study reveals how Seawall Savers employed foam grouting techniques to restore the integrity of the seawall.
Saltwater corrosion accelerates the degradation of concrete, steel, and other materials used in seawall construction. Coastal development in Florida often involves reclaiming marshland. This can lead to sinking seawalls and gaps that allow sediment to wash away.
Daily tidal movements, wave action, and storms exacerbate these issues, highlighting the need for proactive maintenance and repair. Many seawalls are significantly degrading because of age. (35 to 50 years olds)
Effective soil erosion mitigation is essential not only for preserving seawalls but also for protecting coastal properties and infrastructure. By preventing sinkholes and erosion behind seawalls, we safeguard adjacent lands including homes, businesses, roads, and utilities. This preservation is vital for maintaining property values and minimizing economic losses associated with erosion.
To combat the erosion issues at Pelican Isle Yacht Club, Seawall Savers utilized advanced long-lasting foam technology. The repair process involved:
Seawall Savers utilized approximately 750 gallons of SW-RP1. A hydrophobic single-component foam resin, to seal leaking seams of the seawall. Activated by a catalyst, SW-RP1 forms a rigid foam that ensures a watertight seal.
A total of 65 grouting injections behind the seawall panel joints, to fill cracks and voids in the soil. This technique creates a compacted mass to prevent further erosion.
Repairing seawalls near docked boats required meticulous oversight to avoid overspray. Workers used floating barriers to contain grout flow and implement effective disposal containment. Each wall section required 100-120 gallons of SW-RP1, with a total of 700-750 gallons used by a skilled three-person crew.
Our advanced techniques yielded impressive results:
Addressing soil erosion is crucial for defending not only the seawall but also for protecting coastal properties and infrastructure. Controlling sinkholes and voids behind the seawall, ensured the safety of the waterfront homes, hard-scapes, pavers, and utilities. This commitment to coastal protection minimizes financial losses from erosion and maintains the safety of waterfront properties.Partner with Seawall Savers for Effective Coastal Protection.
