High-density polyethylene sheet wrapping applied directly to submerged and splash-zone pile surfaces to seal out seawater, oxygen, and marine growth — extending structural service life without dry-docking.
Pile corrosion in the splash zone and tidal zone is the most aggressive form of marine structural degradation. HDPE wrapping arrests active corrosion, prevents further section loss, and can extend pile service life by 20–30 years at a fraction of the cost of pile replacement.
HDPE Pile Sleeving
Prefabricated two-half HDPE sleeve sections clamped around the pile and grouted — rigid annular void fill for structural load transfer.
Epoxy Coating
Marine-grade two-part epoxy applied by trained divers to cleaned pile surfaces — cathodic disbondment and hydrostatic pressure resistant.
Welding Clamshells
Prefabricated half-shell steel clamshells tack-welded then fully welded to the pile — restores original cross-section and load capacity.
