LifeJacket® Galvanic Cathodic Protection System

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.

Customized for Every Application

The LifeJacket® System may be tailored for nearly any type of structural component. We have successfully adapted the LifeJacket® System for a wide variety of industrial, energy, transportation, and commercial applications.

Repairs, Strengthens & Protects

In addition to providing corrosion protection, the stay-in-place LifeJacket® serves as a form for placement of cementitious repair materials for cross-section loss, adding or restoring capacity to a structure.

Delivers Optimal Protection

LifeJacket® is a maintenance-free system – its current output self-adjusts to meet changes in temperature, humidity, concrete resistivity, and a number of other factors, delivering optimum corrosion protection to the structure at all times.
