LifeJacket® Galvanic Cathodic Protection System
The LifeJacket® Cathodic Protection System uses a proprietary zinc mesh anode placed directly against the inside face of a stay-in-place fiberglass form, and is proven to stop corrosion by providing an electrical current to the affected region. This current is produced through a galvanic process and thus, does not require a remote power supply.
The custom fabricated fiberglass jackets are designed and manufactured to fit a wide range of infrastructure shapes and sizes for rapid installation. Along with providing the attachments and components of a cathodic protection system, LifeJacket® also creates a stay-in-place form that is used for a form-and-pump repair of the concrete structure that is being repaired and protected.
The LifeJacket® Cathodic Protection System has successfully been installed on over 20,000 projects globally.
LifeJacket® trade name and patents are owned by Jarden Zinc Products, Inc. STRUCTURAL TECHNOLOGIES is the exclusive distributor of LifeJacket in the US.
