VA Company Uses NCFI’s TerraThane Geotech Foam System to Save Parking Lot, Time, and Money for NC Municipality

TerraThane and Concrete Jack Fixed this Parking Lot

MOUNT AIRY, NC—Concrete Jack, Inc. of Williamsburg, VA, a company specializing in concrete leveling and foundation repair along the Eastern Seaboard and the South, used TerraThane Geotechnical Foam system to help save the parking lot of a Wake Forest, NC auto repair business.

"Parking lots are notorious for sinking from failed storm water structures," says Kirk Roberts, division manager for Concrete Jack. "Water causes erosion around the structures, voids form, voids enlarge over time then the parking lot just collapses. Sinkholes can shut down businesses and cause damage to customer vehicles."

Roberts says the municipality’s public works department determined the joints between the four foot sticks of pipe had been improperly gasketed, or seated, during installation. The pipe saw a continuous flow from a small stream entering at an end wall and discharging into a box culvert crossing a public street. The drop inlet at the downstream junction between the RCP culvert and box culvert also failed at the 18-inch RCP culvert feeding it, which had been repaired multiple times using open trench excavation.

Joints of a leaking storm drain pipe sealed up by TerraThane geotechnical foamAccording to Roberts, "Every single joint spread at four feet intervals along the 300 foot pipe was leaking. There were no gaskets in any of the joints, so all that water was escaping the joints and running through the ground beneath the parking lot. The stream ran constantly, eating away at the pipe bedding; even flowing up above the pipe’s springline. The voids averaged six-inches around the pipe, the parking lot was sure to collapse."

Previous attempts at sealing the joints and filling voids around the pipe—and under the floor of a storage building built atop the ground under which the pipe lay—with concrete had failed.

Roberts says the municipality was looking for an affordable, proven, and nondisruptive solution, so his company used a relatively new technology to solve the growing problem. "We surveyed all the joints, drilled holes, and pumped TerraThane high density, hydroinsensitive polyurethane geotechnical foam into them until it came back out of the holes and open joints. The foam fills every crack then expands and cures in place. It’s about the cleanest, quickest, least intrusive product ever invented for geotechnical work." Concrete Jack placed 50 cubic yards of NCFI’s TerraThane, and 45 gallons of polyurethane resin chemical grout over a period of three days to complete the repair without disruption to the adjacent businesses or streets.

Roberts adds, "The old way would have shut down traffic to the business. We’d have had to either tear up the parking lot, excavate, replace the pipes, and replace the parking lot, or use heavy, messy, cement grout and that would only put more undue weight on the ground around the pipeline and be a nightmare trying to work around the four or five other pipes crossing the troubled pipeline. It would have taken weeks or even months, but TerraThane is quick and really cuts down on the amount of people and equipment it takes to do the job."

When asked about TerraThane, Roberts says, compared to other systems they’ve have used in the past, NCFI’s experience and service has been outstanding. "They [NCFI] were one of the first companies to develop plural component polyurethanes for geotechnical applications and they manufacture the highest quality products on the market. They are always on call for us, which is like having a partner who knows everything there is to know about geotechnical applications a phone call away."

The parking lot was saved in record time, the auto repair business stayed open, and the foam fix will last of years to come. Roberts says his company will use TerraThane on their concrete lifting, void filling, and leveling jobs from NY down to NC and all points in between.

TerraThane Geotechnical Foam Maker, NCFI Polyurethanes, Turns Fifty

NCFI Polyurethanes - 50 Years of Foam

Founders Included Chemist from Manhattan Project, Pioneer of Urethanes, and Charlotte-Based Cotton Company

MOUNT AIRY, NC—NCFI Polyurethanes, an international manufacturer of rigid and flexible polyurethane foams turns 50 this year. The Mount Airy-based company got its start in 1964 as North Carolina Foam Industries through a partnership between Dr. Harris W. "Ace" Bradley, who had worked on the Manhattan Project during WWII and with Dupont in discovering and pioneering urethanes in the 1950s, and the Barnhardt family, founders of the Barnhardt Manufacturing Company.

"There was a company in Mount Airy getting out of the synthetic foam rubber business," says Lewis Barnhardt, president and COO of Barnhardt Manufacturing Company, Charlotte, NC. "Ace Bradley was working there at the time, and he called Jake Barnhardt with the idea they step in, buy the equipment, rent the facility, and rehire the company’s employees so they would have a ready-made customer base for the new company they named North Carolina Foam Industries. Bradley and the Barnhardt family put together a team of 30 employees to make and sell the foam in large blocks called buns then shipped them to customers who fabricated the buns into cushioning units for furniture, and it’s been a whirlwind of growth for 50 years."

The breakthrough moment for the company came when Dr. Bradley perfected the "One-Shot" production method for foam that allows a continuous production process of simultaneous polymer formation and expansion to form the foam. Dr. Bradley’s/NCFI’s One-Shot method has become the US manufacturing standard, and Bradley was inducted into the Flexible Polyurethane Hall of Fame for the game- changing discovery.

Since 1964 the company has expanded in size with manufacturing facilities in Mount Airy and Hickory, NC, Dalton, GA, and Salt Lake City, UT. The company maintains 14 distribution facilities around the nation. Today the company provides foam for many diverse industries. On the Consumer Products side is furniture, airline, marine, medical, mattress and pillow, and carpet underlay. On the Specialty Products side is spray foam (SPF) insulation for residential, commercial, agricultural, and geotechnical uses, roofing, adhesive, aerospace, taxidermy, and custom molding.

Steve RiddleSteve Riddle, president of NCFI, says, "We changed our name to NCFI back in 2005 to better reflect our national presence, which is becoming more of an international one. We were shipping product to Canada, Mexico, and South America back in the 1970s. We added Russia in 1993, then Africa and Australia, now Eastern Europe, and the Middle East.

Riddle says the company has many watershed moments over the years: "Our foam has the highest content of renewable raw materials anywhere. We’ve become the leader in supplying foam to the commercial and general aviation market, and we offer over 125 different grades of foam to meet almost any customer requirements. He adds that another source of real organizational pride is the work they’ve done for NASA’s Space Shuttle program. "We were chosen in 1980 to supply the foam insulation for Lockheed Martin’s External Tank Program (ET) for the US Space Shuttle program. Over the many years since, we’ve had a great relationship with Lockheed and NASA. We’ve even met some shuttle pilots and crew." NCFI was awarded Lockheed Martin’s Supplier Quality Excellence Award in 2010.

Riddle points to another source of immense company pride—being a US chemical company awarded the EPA’s Stratospheric Ozone Protection Award (now the Montreal Protocol Award). "We’ve worked hard to be responsible stewards of the world around us. Not just North Carolina, but every facility we are involved with, our products, and how our products are used. The EPA award says NCFI stands out as one of the best US companies when it comes to eliminating emissions of ozone- depleting substances, and that has always been part of our mission. To make as big a mark on the world as we can with our quality and processes, but to leave as small a footprint as we can."

Two of the highest growth industries being affected by NCFI are the US construction and homebuilding. Higher than predicted rises in the cost of petroleum and electricity make the energy efficiency of buildings a top priority for building owners and homeowners. Everyone in the process from architects and designers on down to the general contractors and home builders are searching for ways to lower the operating costs of buildings, and better insulation plays a key role. Mitch Clifton, director of business dev. for NCFI’s Specialty Products Division, says his company’s spray foam insulation (SPF) has become a building standard. "SPF insulation has the highest R-value in the modern available insulation field. Nothing else comes close. So, we’ve seen amazing growth in our residential and commercial spray foam insulation market. Clifton says the same is true for the roofing market. "Building owners want to lower costs by adding cool roofing, or roofing covered in white or light colors that reflect sunlight. Our roofing systems add the R-value of SPF insulation to that reflective feature and drop the heating and cooling costs dramatically. We’ve seen steady growth in roofing since we did our first job back in 1967."

Clifton credits employees who’ve made a 20, 30 and 40-year career at the company with giving NCFI a definitive competitive advantage. "Spray foam insulation is something everyone wants now, but until recently has been a small sector of the insulation market, thus few know much about the product. Architects and builders and trade contractors want experience. They want a partner who has seen and done it all. Someone they can turn to when they need answers in their business. We have that in spades."

Clifton knows what he’s talking about. His father, Ralph, was one of those first 30 employees in 1964 and worked at the company for more 42 years until his retirement. His son followed in his footsteps by working on the loading docks while in high school. Clifton [Mitch] who received his MBA last year, is now in senior management and says, "We buck all the trends: we’re a family-owned US company; we make products right here in this country, and the people who work here can choose to make a lifetime career with us. We’re a private, profitable US company willing to change to grow, and we’re celebrating our first 50 years. It’s good to know that still exists in America. Maybe we’re setting the trends for the next 50 years."

Additional Tests Boost KeyLAB’s Appeal

Over the last 18 months Peter Keeton has been heading up a team at Keynetix to write British Standard and ASTM Standard compliant test definitions, laboratory worksheets and reports for KeyLAB. This work has now been included free of charge with the latest installer of KeyLAB and enables new users of the software to be operational much quicker than ever before.

Peter Keeton has over 40 years of experience working in and managing geotechnical laboratories for Soil Mechanics and was an influential member of the CEN European Standards working group on geotechnical testing. Over this time he has produced many versions of laboratory worksheets for each test.

“By including the latest versions of Peter’s work into the system we have already seen an increase in the number of customers who are running trials of KeyLAB” said Dr Roger Chandler, Keynetix Managing Director. “The out of the box value of KeyLAB has increased significantly with this work and many users are now adopting the system with the standard sheets and only need to modify them with their company logos and details.”

Peter has also been working more with small and medium sized laboratories to help them use the software efficiently and prepare for gaining accreditation status.

In order to assess the current status of a laboratory’s progress toward accreditation, Peter conducts an in-depth independent audit covering all of the accreditation elements. The audit report provides the laboratory with a good understanding of that status and more importantly, identifies any and all deficiencies. The laboratory can then, with guidance and assistance from the auditor and Peter, produce a detailed plan for improvement.

“Having been working in the background for the last 18 months with KeyLAB I am really enjoying the challenge of helping laboratories implement the software and working towards accreditation” said Peter Keeton. “We will have the final tests available over the next two months and by the end of April should have most of the standard BS, ASTM and Rock testing covered, as well as our previously announced enhancements for concrete cube, cylinder and core testing. As most LIMS systems charge per test, I have advised the board in Keynetix to raise the price of KeyLAB once all tests are available as the product will include around a man year of my work and allow laboratories to cut their implementation time by many weeks.”

KeyLAB trial copies are available to laboratories who wish to investigate the system further by visiting www.keynetix.com/keylab

Laboratories can employ Peter as part of their preparation for UKAS accreditation and should contact Keynetix directly at http://www.keynetix.com/contact-us/

“Foamjacking” Solution for Seneca Rocks USFS Visitor’s Center


Seneca Rocks Visitor's Center was experiencing geotechnical foundation problemsU.S. Forestry Service Saves Thousands with Use of TerraThane Geotechnical Foam by NCFI Polyurethanes at Seneca Rocks Discovery Center

MOUNT AIRY, NC— Seneca Rocks Discovery Center, the visitor’s center for the eastern U.S.’s most popular rock-climbing destination located in Pendleton County, WV, had a growing problem common to concrete slab foundations: erosion of the soil beneath the slabs created voids that left areas of the center with uneven spots and settled anywhere from one-to three inches. That led to cracks in interior walls, uneven floors, and trip hazards for the thousands of visitors to the area’s most popular scenic attraction. Seneca Rocks is a striking 900 ft peak that features over 375 mapped climbing routes varying in degree of difficulty from easier 5.0 to the hardest 5.13, and attracts climbers from around the world.

Injecting NCFI polyurethane foam to fill voids and cracks beneath the Seneca Rocks Discovery CenterAny solution to the problem had to be quick, clean, affordable, and not cause inconvenience for the daily visitors to the U.S. Forestry Service building. “They can’t just close down,” said Eddie Bolton, president of Mid-South Concrete Leveling, Milan, TN, the company chosen to help solve the problem. “This is a world-class climbing venue. They have visitors coming from all over to climb and visit, so they couldn’t just close down the building for repairs.”

Bolton says ten years ago the U.S. Forestry Service would have been out of luck, as there were only two solution: close down, tear out the concrete, fill the voids, and repour the slabs which can take months, or mudjacking which involves closing down most of the area, drilling large holes in the concrete which causes a good deal of dust, and using large hydraulic hoses to pump in a slurry of “mud”, a grout made up soil, crushed limestone and concrete to fill the void and lift the sunken slabs to level. It’s messy, time-consuming, and, again, requires the facility to close part if not all of the facility being worked on for weeks, maybe months.

Mid-South Concrete Leveling truck at Seneca Rocks Discovery CenterBolton, who has 40 years of experience with the effects of erosion on concrete slab foundations, sidewalks, and curbs, suggested Seneca Rocks use a newer technology called TerraThane Geotechnical Polyurethane Foam System by the U.S. company, NCFI Polyurethanes. “We call it foamjacking,” says Bolton. “It only took us three-and-a-half days to partition off the immediate small areas in which we worked drilling small 5/8 inch holes in the slabs, running small lines to pump in polyurethane foam that filled the voids in the soil, lifted the slabs to level, and cured in place in no time at all. It’s so much cleaner, quicker, and less intrusive to work of the Discovery Center.”

TerraThane is an ideal product for this work. Not only is it easier to use, it’s actually lighter than mud grout—4 lbs. compared to 130 lbs. of concrete grout—so it doesn’t further destabilize the surrounding soil by adding all that pressure.” Bolton adds, “NCFI has been manufacturing foam in the U.S. for 50 years, so they know what they are doing, and we trust them. TerraThane is the future of concrete leveling, soil stabilization, void filling,and geotechnical problem-solving areas, there’s no doubt about that.”
