Hurricane Sandy caused extensive damage to the basement of the World Trade Center.  Standing salt water caused extreme corrosion damage to sensitive areas of its basement.  These areas were not designed to be subject to water or salt corrosion.  The flooding caused structural damage to anchors in certain areas.  Structural Preservation Inc. hired Atlas Anchor in conjunction with its 40 million dollar Hurricane Sandy Salt Water Remediation Project. to do pull testing on Nelson Studs embedded within the concrete to determine how corroded they were from the saltwater and flooding.  Atlas Anchor designed a test that was the first of its kind in the world.  The test involved measuring the elongation, displacement, and tensile strength of concrete embedded Nelson Studs behind a steel wall.  The test was successfully executed and provided definitive data on the corrosion, to the Port Authority of New York New Jersey and to the contractors and engineers.
