Experienced concrete maintenance and restoration specialists explain the unique challenges in protecting parking structures from a constant onslaught of environmental stressors and wear and tear, along with examples of successful repair techniques.
One of the areas where cathodic protection is commonly applied to marine structures for corrosion protection is the steel piling systems on jetties and piers. This article discusses the design and implementation of CP on a newly constructed jetty in Surabaya, Indonesia.
Some unique capabilities of cathodic protection design methodology are showcased with grillage-type foundations for power transmission structures.
A major U.S. university is using funding from Phillips 66 to develop a new outdoor pipeline integrity lab, which will include buried pipe with an active rectifier to simulate real-life activities.
One of the most common drivers of concrete repairs is corrosion of the concrete’s steel reinforcement, often caused by chloride ions in the environment entering the concrete and eventually reaching the embedded steel.
Advanced polyurea coatings and liners can provide strong, flexible waterproofing to bridge cracks and protect against future cracking and deterioration.
As pipelines age, it is important to verify the effectiveness of the coating and cathodic protection systems that protect them against external corrosion, and implement remedial actions if necessary.
