Marine Pile Repairs by Concrete Encasement

Piled jetty and pier structures form a vital part of port infrastructure for worldwide trade and travel, yet their life span is often threatened by pile deterioration in the corrosive marine
environment.

Many steel piles suffer from Accelerated Low Water Corrosion (ALWC) or Anaerobic Corrosion with significant section loss well before the design life of the structure expires. Port Owners and Engineers should respond by monitoring corrosion and steel thickness loss and provide appropriate protection or repair.

The protection and repair of marine piles is usually much more sustainable than jetty replacement, yet little published guidance is available.

The process of concrete encasement repair using a fabric pile jacket system will be described with reference to case histories of its application, to both steel and reinforced concrete (R.C.) piles.
