Posh Dallas Parking Center Saves Millions with TerraThane Geotechnical Polyurethane Foam by NCFI

Underground parking garage in 'Uptown' area of Dallas that needed TerraThane polyurethane foam

MOUNT AIRY, NC—In-ground parking garages in Dallas, TX experience the same thing: erosion of the soil beneath them, and silt infiltration that overwhelms and clogs the drainage system, thus causing more and worse erosion. The keys are catching it early enough, and choosing the right solution to keep it from happening again.

The three-story, in-ground parking garage at McKinney Ave. and Worthington St., the main thoroughfare of the Dallas’ “Uptown” area and home to some of the poshest apartments, business addresses, shopping, hotels, restaurants and bars, had silt and water infiltration, so the owners called in Edens Structural Solutions, Bixby, OK, with 30 years experience of structural lifting and repair. David Edens, company president, says they studied the problem and decided on geotechnical polyurethane foam. “Our solution was to use void-filling TerraThane geotech foam. It’s simple to apply, expands and cures in place, and is an excellent water and air barrier,” says Edens.

They drilled a shaft down along the piers and soldier piles and lagging, to survey the problem and found the water had gone through the block wall and carved out what appeared to be a five-foot cavity. Soldier piles and lagging is an earth retention technique that retains soil using vertical steel H-shaped piles usually spaced between three and ten feet apart with horizontal timber sheeting called lagging.

“We chose NCFI’s TerraThane foam, but we first had to do some geometry to figure out how much to use. We didn’t quite know the full size of the cavity, even after using a boroscope and ground-penetrating radar, but we knew it ran at a right angle, so we used the Pythagorean Theorum to find the length of the hypotenuse and that told us the size. We ran a 3/8 vinyl tube behind the block and dropped in the TerraThane polyurethane foam.”

Edens explains, “TerraThane gives us four products in one. It fills It fills in large and small voids running both vertical and horizontal in the cavity, serves as water and air barrier so it will impede future water and silt infiltration, it’s amazingly strong, and it’s light, so it won’t add any weight to the block wall. It was ideal for this project. We were in and out in two months without minimal disruption of the parking. The alternative would have been to shut the entire structure down for a year-and-a-half as they removed the entire block wall, dug out the lagging, installing 26 gauge panels, then backfilled the cavity with gravel. That might have cost upwards of $2 million or more, plus loss of parking revenue. TerraThane saved this one and the owners have asked us back for more work.”

Edens says his company has been using NCFI products for years. “We also use their concrete lifting foam, and their trench-breaker foam. We trust the products and we trust the company. We like that they’re a US company with over 40 years experience, so they know their products and they know how to apply them. They are one of the only major companies out there to send their engineers and tech people to our job sites. We’re doing a big job in Austin, and they sent two guys down to make sure they sold us the right product and to make sure the application process we chose was ‘best practice’. That little extra makes a huge difference to my bottom line.”

Datgel’s CPT Tool 3 places advanced reporting capabilities directly in the hands of geotechnical engineers

Sydney, Australia – 21 August, 2012 – Datgel today announces the launch of CPT Tool 3 gINT add-on, the third-generation of its category-defining CPT reporting tool which places advanced reporting and analysis capabilities directly in the hands of geotechnical engineers with an array of formula configurations and report generation options unmatched in cone penetration testing.

CPT 3 is the most flexible CPT software available and ensures geotechnical engineers can have custom reporting with rich-data visualisation in any situation, adapting reporting output quickly and cost-effectively as user-requirements change to meet new conditions across locations and projects.

“In developing CPT Tool 3, our focus has been on automation and user control,” says Datgel Managing Director Phil Wade.

“Version 3 gives geotechnical engineers faster access to the exact information they need to be effective, defining their own calculations and report parameters by leveraging peerless formula-creation tools in CPT Tool 3 to write formulas for gINT without having to develop lines of complex VBA code.”

User-definable features include a library of more than 300 customisable log, graph and fence reports that can be modified to capture unique requirements on the day. The ability to create and store a repository of user-defined calculations and reports within the system can be utilized to create a dynamic workflow over time for highly efficient CPT data processing.

CPT Tool 3 sets a new level of productivity in report generation according to Wade.

“Reporting is streamlined with multithread calculations, dissipation tests, derived parameters, six soil behaviour type (SBT) interpretation methods and more than 100 preconfigured correlations including liquefaction that all take the burden of creating complex calculations off the end-user.”

Client feedback from version 2 has been taken into account including requests for English units, liquefaction and pile analysis.

“It’s important that geotechnical engineers focus their highly specialized skills on analysis and interpretation,” says Wade. “CPT Tool 3 takes clients beyond having to wrestle with 100’s of Excel spreadsheets while delivering superior presentation of the essential and critical data they need. Reporting capabilities include being able to compare borehole logs, lab results and CPT data in the same gINT database – unheard of until now.”

CPT Tool 3 is built for speed and ensuring data integrity. High-volume data processing is catered for with secure, centralized data storage that facilitates robust data retrieval and analysis and a single point of control for sharing across disparate geographical sites. CPT Tool 3 also encourages the re-use of stored data, whether for benchmarking, extended testing or comparison with other data sets and re-interpretation – in short, treating data as an asset.

Tensar’s HDPE Geogrids Complete NTPEP Audit

ALPHARETTA, Ga. – Aug. 13, 2012 – Tensar International today announced its high-density polyethylene (HDPE) Uniaxial (UX) Geogrid product line successfully completed the National Transportation Product Evaluation Program (NTPEP) on-site audit.

As the on-site audit was added just last year to the program, Tensar’s UX Geogrids are the first HDPE Geogrids to pass the rigorous evaluation.

“We are committed to providing quality products to our clients,” said Willie Liew, Application Technology Manager at Tensar International. “We have been proactive in the process by starting the NTPEP audit a year before our current report expires in 2013, and are proud to have our manufacturing process and quality control system successfully complete the audit.

The NTPEP audit assesses the long-term design strength of geosynthetic reinforcement products and provides performance test results as well as index test results. The evaluation includes a desktop review of the facility’s quality manual and an on-site review of the facility’s processes and quality management system documentation.

More state Departments of Transportation (DOTs) are utilizing the NTPEP for product qualification because the program is highly recommended in the current Federal Highway Administration (FHWA) and American Association of State Highway and Transportation Officials (AASHTO) Mechanically Stabilized Earth (MSE) wall/slope design guidelines.

“Having the geogrid evaluated through an independent party and through the high standards of the NTPEP provides credibility to our UX Geogrid product line and provides the reliability the state DOTs can count on,” Liew said. 

The NTPEP audit is a program under the sponsorship of AASHTO and was developed by industry members and state DOT members to provide a uniform program, which allows for all manufacturers and private label suppliers to be held to a consistent standard internationally. The audit improves quality assurance and proves to the states which manufacturers have satisfactory quality control.

Tensar’s UX Geogrids are manufactured using select grades of HDPE resins that resist elongation (creep) when subjected to high loads for long periods of time. They carry large tensile loads applied in one direction (along the roll), and their open aperture structure interlocks with natural fill materials. UX Geogrids are used in Tensar’s retaining wall and slope stabilization applications.

With the on-site audit complete, Tensar is currently in the process of finishing the remainder of the evaluation program. The expected completion date of the evaluation is summer of 2013.
