HJ3 Composite Technologies is the worldwide manufacturing leader of engineered composite repair systems to strengthen critical infrastructure. Our patented carbon fiber systems are stronger per ply, code compliant and supported by same day engineering and shipments.
In addition to manufacturing the strongest and most durable carbon fiber repair systems, HJ3 provides our customers unmatched customer service and response time.
HJ3 will design repair solutions for your tank, concrete, silo, and pipe repairs the same day we receive a completed Engineering Assessment Form (EAF).
Our code-compliant Engineered Composite Repair kits will ship the same day we receive your order.
HJ3’s line of pipe and pipeline repair systems are designed to address corrosion, erosion, dents, weld defects and metal loss common with pipeline operation with code-compliant solutions requiring little to no downtime.
HJ3's tank repair systems are customized for external and internal strengthening of steel and concrete tanks, serving as a structural liner restoring steel loss while protecting against harmful chemicals in immersion.
HJ3's line of silo repair systems are designed to repair concrete silo degradation due to abrasion and old age using high-strength uni-axial carbon fiber reinforcement that is corrosion resistant and FDA Compliant
HJ3's line of concrete repair and strengthening systems include injection, patching, and glass & carbon fiber composite reinforcing wraps designed for concrete patching & repair, structural strengthening and seismic retrofits of concrete, masonry, steel, and wood structures.
Address a wide range of temperatures, pressures, geometries and chemicals, offering a safe and cost-effective solution to common integrity problems.
Customized for external and internal strengthening of steel and concrete tanks.
Designed to repair concrete silo degradation due to abrasion and old age.
Include injection, patching, and glass & carbon composite reinforcing wraps for concrete patching & repair, structural strengthening and seismic retrofits.
Designed specifically for transitioning composite repairs over big changes in geometry like stop gaps, enclosures, flanges and valves.
A pre-impregnated urethane-based fiberglass wrap designed to be ideal for lower pressure, lower temperature applications in environments where a moisture tolerant material is required.
Protect concrete and steel structures from exposure to more than 300 chemicals common throughout industrial processing facilities.
Offers 1 to 3 hours of fire resistance when applied to HJ3 composite repair systems. Systems also prevent flame and smoke spread in the event of a fire.

"Carbon fiber is becoming the material of choice for retrofit and repair in our process facility because it's lightweight, there is no downtime in the installation, and it can be installed very easily around the existing infrastructure. Some of the applications we've used carbon fiber for are corroded piping systems, columns and beams within process facilities, underground tanks and internal linings of major pipe systems."
