Maintaining piping integrity within petrochemical plants and refineries is critical to operations. HJ3’s line of engineered repair systems is designed to address a wide range of temperatures, pressures, geometries and chemicals, offering a safe and cost-effective solution to common integrity problems. Whether it’s preventive repairs associated with a CUI program or emergency repairs on your flare line, HJ3 can offer a solution to extend the life of corroded or damaged piping in your facility. All HJ3 engineered repair systems conform to ASME PCC-2, ASME B31, ISO 24817, DOT, API.

The StrongHold™ System meets the tough demands of your concrete applications. Whether it’s protecting structures exposed to aggressive environments or strengthening your damaged concrete, our systems save you significant money over traditional repairs or replacement. The StrongHold Concrete Repair Systems are designed for multiple applications, including beams, columns, walls, slabs, pedestals, silos, and secondary containment. The StrongHold carbon fiber is lightweight, flexible and conforms to any substrate for easy installation. StrongHold Systems provide many types of strengthening, including crack confinement, flexural strengthening, shear strengthening, seismic strengthening and protection against harsh chemicals, abrasion, heat and fire.

SiloWrap™ offers tensile strengthening, abrasion resistance, and electrostatic dissipation to extend the life of your concrete silos. The system installs faster, easier than shot-crete systems, and eliminates the added mass and difficult construction associated with shot-crete repairs.

StrongHold™ Manhole Repair Systems are designed to strengthen your manholes to resist soil movement and surface cracking, while protecting your manhole from harmful hydrogen sulfide gas exposure. StrongHold is lightweight and conforms to the inside surface of masonry and concrete manholes for easy installation. Following installation, the systems are tested until determined to be pinhole free, allowing HJ3 to offer a 10-year warranty.

The ChemSeal™ Systems are designed for multiple applications, including trenches, primary containment and secondary containment. The systems incorporate high strength polymer grouts and reinforcing systems to return these structures to full strength and resist harmful chemicals. Not only are HJ3 products 40% to 50% stronger than competitors per ply, they are designed to withstand high temperatures, abrasion and aggressive chemical environments.
