Case Study Details

By 2013, the Lake Park Marina seawall repair in Palm Beach, Florida, experienced severe soil loss behind the seawall, causing sidewalks to buckle and fail. The Palm Beach marina project’s concrete seawall, meant to protect the marina, lacked an adequate concrete seawall drainage solution – leading to hydrostatic pressure buildup that compromised structural stability. Without a sustainable seawall drainage system, continuous erosion behind the seawall could lead to further infrastructure failure, increased maintenance costs, and safety concerns for marina visitors.

Products Used

• 14 units of JET Filter – JF4SS: 4″ Diameter Open End Maintainable Weep Hole Filter with ASTM 316/316L Stainless Steel Housing and Mirafi® Filter-Weave FW 300 Geotextile Filter Media.

Solutions

To prevent these issues, the Town of Lake Park sought a proven, maintainable drainage solution to preserve the integrity of the seawall and protect the surrounding infrastructure with seawall erosion control. JET Filter’s advanced drainage technology provided an effective solution to hydrostatic pressure management, seawall erosion control, and preventing excessive water buildup behind the seawall. This concrete seawall drainage solution extended the seawall’s lifespan, stabilized the marina’s infrastructure, and minimized ongoing maintenance needs. The project was successfully executed by Sea Me Dive, ensuring strict compliance with best engineering practices for marine drainage solutions.
