Salt Mining Facility Concrete and Steel Repair

Posted on by Marci Broderick
Over 60 years of salt mining had deteriorated this facility. Walls,
columns, beams and secondary members had significant
efflorescence, spalling, steel loss and structural degradation.

The facility, located near Lake Huron, is susceptible to severe lake storms creating excessive moisture and extreme cold. The salt production environment causes significant chloride ion migration, rebar swelling/popping
and subsequent concrete spalling.
Carbon fiber on beam
HJ3 engineered a composite fiber system to replace the lost tensile strength and shear reinforcement in the external wall, targeted columns, and internal supports. The CarbonSeal™ repair restored the strength of the facility, repairing and strengthening 9,800 sq ft surface area with 20,000sq ft of carbon fiber, extending its life by up to 30 years.

Bridge Pile and Truss Repair

Posted on by Marci Broderick

For this bridge and pile repair project, HJ3 repaired and strengthened a bridge that had 93 concrete piles and 2 reinforced trusses in need of repair and strengthening. HJ3’s patented products were used to repair and strengthen the piles 10 feet above and 5 feet below the waterline.

For this project, HJ3 had an above-water and below-water team of certified installers. The degraded concrete was removed and the piles and trusses cleaned.
5 Bridge with many piles over water
The bridge was repaired and strengthened above and below the water, then wrapped with HJ3’s carbon fiber and CFRP. The piles above water had a UV and pH protective coating applied over the carbon fiber.

DESIGN: HJ3 relies on ACI-440.2R-08 ” Guide for the Design & Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures

STRENGTH: HJ3 verified the strength of its underwater system in accordance with ASTM D3039.

Industrial Asset Life Cycle Infographic

Posted on by Marci Broderick

Much of our nation’s infrastructure is at the end, or past its serviceable life. HJ3’s carbon fiber technologies have advantages that go beyond cost savings and asset life extension. The environmental savings are huge. This infographics details some of the positive impact carbon fiber solutions provide.

U.S. ranks well behind many other countries in overall infrastructure quality in 2014-2015, coming in at 16th.

By 2020 the transportation infrastructure investment gap will be -$1 trillion. Investing in rail expansion would have many long-term benefits both financial and ecological. It is estimated that traffic congestion caused U.S. drivers to waste around 3 billion gallons of fuel in 2014. When time, fuel, car maintenance and lost productivity are factored in, the price tag is a staggering $160 billion dollars nationwide. Investing in passenger and freight rail expansion makes financial sense. This infographic highlights some of the other costs and benefits investing in rail expansion would provide.

Giving Back

HJ3 Giving Back

Giving back is an integral part of HJ3’s corporate culture. At HJ3 we pledge 1,000 hours of community service each year.

Each year as part of our commitment to give back to our community, we work with the Salvation Army to select families for our annual holiday Adopt a Family event. In years past, we would adopt several families. This year we adopted one family, so that we could make a big difference for a struggling family. We adopted a single mother with 6 children. One of her children is special-needs and another was hit by a car and sustained many serious injuries. Mom took off work to care for her injured child, which had a major impact on the family.

We’ll deliver gifts and food that were purchased and wrapped with the children and mom in mind.

Other Giving in 2015

This year HJ3 donated to Pima Animal Care Center, providing food, supplies and money for the care of pets in need. We also participated in our annual Cystic Fibrosis Walk, and the 2015 Walk For Wishes Tucson, which is part of the Make A Wish Foundation. HJ3’s contribution helped Walk For Wishes Tucson raise thousands of dollars to help grant the whishes of children with a life-threatening medical condition.

We would like to thank our customers and friends for making 2015 a special year. The HJ3 family is committed to enriching our community and spreading hope and joy. Have a happy and peaceful holiday.

There are 87,359 Dams in the US. Their average age is over 53. Many are in need of repair and are considered to pose a high or significant hazard potential.

Many communities are located downstream of dams.
