Splash Zone Piling Composite Repair
Wasted splash-zone piling rebuilt and reinforced with an engineered composite wrap, no welding and no pile replacement.
A job completed with Belzona. This describes what the Belzona system does and how it goes on, not a record of a specific project by this distributor.
The challenge
A structural piling wastes fastest in the splash zone, the band that wets and dries with the tide and stays loaded with oxygen and salt. Corrosion eats the steel there while the sections above and below the water still look sound, so the loss of wall thickness is easy to miss until it threatens the load the piling carries. Once the section thins enough, the structure loses capacity and the whole platform or jetty is put at risk. The owner needed the wasted section brought back and reinforced without welding on a load-bearing pile and without cutting it out.
The Belzona approach
Gauging the piling above and below the waterline finds the worst metal loss in the splash zone. The wasted section is cleaned and roughened back to sound steel, then the lost wall is rebuilt with a cold-applied composite to bring the profile back. Over the rebuilt steel goes an engineered SuperWrap II composite, designed to carry load and reinforce the section without any hot work on the pile. The repair cures in place and the piling goes back to carrying its load with a barrier between the steel and the splash zone.
- Assess and mapThe piling is gauged through the splash zone to locate the worst metal loss and confirm the section that needs to be rebuilt and reinforced.
- Surface preparationThe wasted steel is cleaned and roughened back to a sound, profiled surface so both the rebuild and the wrap bond properly.
- Rebuild lost wallA cold-applied 1000 Series composite rebuilds the thinned and wasted steel to restore the original profile, with no welding.
- Install the composite wrapEngineered SuperWrap II layers are built up over the rebuilt section to reinforce the pile and seal the steel from the splash zone.
- Cure and return to serviceThe wrap cures, the finished repair is inspected, and the piling goes back ready to carry its load.
The result
- Wasted splash-zone section rebuilt in place without cutting out or replacing the pile
- Piling reinforced with an engineered composite wrap and no welding on the load-bearing steel
- Steel sealed from the wet-dry, salt-laden splash zone under one continuous barrier
- Work delivered by factory-trained and factory-certified Belzona applicators
