Vinyl Seawall Installation in West Palm Beach, FL — JKT Marine Construction
Vinyl Seawall Installation in West Palm Beach, FL
JKT Marine Construction recently completed a new vinyl sheet pile seawall installation on a residential canal property in West Palm Beach, Palm Beach County, Florida.
The Project
The property's existing concrete seawall had reached the end of its structural service life after more than 40 years. Internal rebar corrosion had compromised the cap throughout its full length, several panels showed horizontal cracking indicating tie rod failure, and soil erosion behind the wall had created visible depressions in the yard near the seawall edge. The homeowner had received a recommendation for full seawall replacement during a JKT Marine free inspection the prior spring.
After evaluating the site conditions — a protected residential canal with moderate boat traffic and good land-side equipment access — our team recommended vinyl sheet pile as the replacement material. The canal's conditions did not require the structural mass of concrete, and vinyl's superior corrosion resistance made it the better long-term choice for this property's protected saltwater canal environment.
What We Did
Our crew removed the existing concrete panels and cap, inspected the underlying soil conditions, and drove new vinyl sheet pile panels to the engineered embedment depth using land-side vibratory hammer equipment — no barge required given the site's land access. Tieback rods were installed through the vinyl panels and connected to new deadman anchors at the engineered depth behind the wall. We then formed and poured a new reinforced concrete cap to current Palm Beach County elevation standards, finishing the full cap length before conducting the final county inspection.
All permits were managed by JKT Marine throughout the project — Palm Beach County Building Department and SFWMD. The project was completed on schedule with no change orders.
The Result
The homeowner now has a new vinyl sheet pile seawall with a design service life of 40 to 50 years — completely corrosion-resistant, requiring minimal maintenance, and built to current Palm Beach County elevation and engineering standards. The property's yard was restored after installation and the seawall cap was finished to a clean, consistent profile along the full wall length.
