HJ3 Composite Technologies offers the most comprehensive line of strengthening products in the world for fortifying and protecting structures against earthquakes, blasts, and environmental damage.

Tank Repair
HJ3’s system of carbon fiber composites can be used to repair large steel and concrete tanks used for storage or processing of aggressive chemicals. These high strength composite systems are capable of restoring the tensile strength of corroded steel and concrete tank walls that have deteriorated from exposure to aggressive acidic or alkaline chemicals. The HJ3 system also provides additional chemical protection and has been tested to withstand chemicals ranging from pH 1 to pH 13 in over 20,000 hours of continuous exposures. >> More Details

Pipe Repair
Corrosion of steel reduces pipe strength and service life. Traditionally, owners are forced to replace the damaged pipe, requiring extensive downtime, the use of heavy equipment and excavation.
HJ3 Composite Systems structurally repair and restore damaged pipe. Installed internally or externally, HJ3 Composite Systems return the pipe to its original design value without costly downtime, heavy equipment or excavation. >> More Details

Support Structures
Whether columns, beams, or walls, HJ3’s high strength composite systems are the perfect cost-effective repair and strengthening system for plant support structures. These composite systems can be used with appropriate top coats (such as fireproofing) to retain plant standards. Typical applications include corroded columns, piping support beams, secondary containment areas and control rooms.
