Bair Island Marina
The Problem
Bair Island Marina in northern California was experiencing severe corrosion of the steel waler that prevented the sheet pile wall from overturning. A new structural beam encasement was needed to replace lost capacity and control corrosion over the existing waler. Engineers were concerned that the steel waler would continue to corrode after the new structural beam was cast around it.
Our Solution
Galvashield® DAS Type M anodes were installed to control the corrosion on the steel walers. New reinforcing elements were added to compensate for any lost capacity of the steel walers over time. Due to the high surface area of the steel walers, several rows of Galvashield® DAS anodes were needed to control corrosion for the desired service life.
The Result
The Galvashield® DAS Type M anodes will control the corrosion in this marine environment for decades and prevent the new structural concrete beam from deteriorating.
