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.
Customized for Every Application The LifeJacket® System may be tailored for nearly any type of structural component. STRUCTURAL TECHNOLOGIES has 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.
CORROSION SOLUTIONS STRUCTURAL TECHNOLOGIES integrates proprietary products and systems with specialized investigative and design support services to provide solutions for controlling corrosion in reinforced concrete and steel infrastructure. We offer a full suite of systems – including both impressed current and galvanic solutions – to accommodate a wide range of structural life expectancies, budgets, design considerations and maintenance requirements. Our products can be used stand-alone or in combination to solve complex project challenges.
