The Problem: Failing Sidewalks & Dangerous Sinkholes Lead to Concrete Seawall Repair and Installation of Maintainable Weep Hole Filters.
Lake Park Marina, located in Lake Park, FL, was built in the early 1990s. Situated on the Atlantic Coast, it experiences a high ground water table, numerous storms and receives 66” of average annual rainfall. By 2013, the marina was in need of extensive seawall repair to stop the soil loss, fill the sinkholes, repair the walkways and the concrete seawall. Finally, maintainable weep hole filters were installed to ensure proper drainage and erosion control.
“Severe Soil Loss”
The marina had been experiencing severe soil loss and sinkholes behind the seawall which caused the beautiful paver-covered sidewalks to become buckled and uneven, with sinkholes forming in many locations. It got so bad, the city placed plywood, wrapped in artificial turf, over the walkways to prevent slips, trips and falls. They knew that they had a problem that was rapidly deteriorating. In 2013, the city called in several professional teams to investigate.
Lake Park Marina’s seawalls are now draining properly. Two years after the seawall repair, engineers were brought in to test the results. Small holes were drilled through the new sidewalks and penetrometer readings were randomly taken around the repair area only to find original repair soil compaction readings with zero soil voids and no soil settlement.
