A waterfront residential property in Oak Island, North Carolina, required an upgrade to its marine drainage system to protect a timber bulkhead from backfill erosion and hydrostatic pressure. In coastal regions, timber bulkheads can trap water, causing pressure buildup, soil saturation, and eventual wall failure. To address these challenges, maintainable weep hole assemblies were installed directly through the newly constructed reinforced timber bulkhead walls, providing critical water relief.
JET Filter System supplied 20 units of the JF2.5ABS, a 2.5-inch diameter open-end maintainable weep hole filter. Each unit features an ABS plastic housing paired with Mirafi® Filter-Weave FW 300 geotextile filter media. The system supports essential soil stability while allowing for long-term maintenance and inspection, making it an effective solution for protecting coastal residential properties from water-related damage.
The project, classified as a wooden bulkhead drainage system, utilized 20 JET Filter JF2.5ABS maintainable weep holes within timber barriers. The work was commissioned by a private homeowner and executed by American Dock & Marine Construction, reaching completion in June 2024.
