Pile repair spacers awarded U.S. patent 2021-01-22
Assorted spacers used by PileMedic to repair and rehabilitate marine piles and columns recently received a U.S. Patent. Spacers are used to repair timber piles and steel h-piles, like the sample pictured here.
U.S. Patent No. 10808412 - Spacers for Repair of Columns and Piles covers important accessories used by QuakeWrap to install the PileMedic® repair system. The patent was issued to QuakeWrap President and CEO Prof. Mo Ehsani, Ph.D., P.E., S.E.
"These spacers are valuable in saving time and money, and for improving the quality of construction for our clients," said Ehsani, who is Centennial Professor Emeritus of Civil Engineering at the University of Arizona.
Exact placement of reinforcing materials such as FRP rebar, and maintaining specified distances between the structure and the specialty laminates, are time-consuming tasks that challenge the efficient repair of columns and piles. The problem is even more consuming for underwater repairs, Ehsani says.

Memphis Area Transit Authority implements CFRP service ramps 2020-12-09
The Memphis Area Transit Authority (MATA) deploys new carbon fiber service ramps on its rail trolley cars using an extremely durable, lighter weight material traditionally used to reinforce concrete buildings and bridges. More than 60% lighter and three times stronger than metal ramps, the new composite ramps bridge the gap between the rail trolley and station boarding platform area, and are easily lifted and put into place by trolley operators.
“This is another application of CFRP that benefits the public,” says Mo Ehsani, president and CEO of QuakeWrap Inc. (Tucson, Ariz., U.S.) and Centennial Professor Emeritus of Civil Engineering at the University of Arizona.

QuakeWrap Wins Federal Research Grant to Explore Gas and Oil Pipeline Repair 2020-06-12
Tucson-based QuakeWrap Inc. is the recipient of a federal research grant from the U.S. DOT to explore a greener, less intrusive repair method using fiber reinforced polymer (FRP) for larger gas and oil pipelines.
"No-Dig Point Repair Technology for Steel O&G Pipelines," recieved a U.S. DOT SBIR Phase 1 grant in the research category of “Internal Repair of Steel Transmission Pipelines (20-PH2).” This is the first SBIR award from the U.S. Department of Transportation for QuakeWrap. Previous small business research awards won by QuakeWrap were from NSF, U.S. EPA and the USDA.
The technology has the potential to repair large pipelines that transport oil and gas from the inside using FRP to reduce, and in many cases eliminate, required excavation to repair pipes conveying hazardous fluids.

An infrastructure innovation coming out of the research labs of Arizona-based QuakeWrap, Inc., and promising to help solve a major problem in city drinking water systems, has received federal funding from the research arm of the U.S. Environmental Protection Agency (US EPA).
The proposal, “Trenchless Water Main Point Repairs with SuperLaminate,” will explore the use of specialized fiber reinforced polymer (FRP) laminates for repair of water main leaks that cost cities and counties millions of dollars a year in drinking water loss.
The new repair method, if successful, will stop identified leaks in city main water pipes without the need for expensive excavation.

(InfinitPipe.com) -- The very first green and sustainable pipe has been awarded a $100,000 federal research grant to explore its potential as a sustainable yet durable resource for agriculture.
“InfinitPipe: An Economical Sustainable Pipe for Agricultural Use,” a proposal submitted by QuakeWrap, Inc. describing this new game-changing pipe technology, is the winner of a support grant from the U.S. Department of Agriculture's (USDA) National Institute of Food and Agriculture (NIFA). QuakeWrap is the only company from Arizona to win the grant.
“The relatively simple construction technique of InfinitPipe will allow farmers to purchase the raw materials and lease the equipment to build the pipes they need,” said Dr. Mo Ehsani, principal investigator of the proposal and a pioneer in the introduction of fiber reinforced polymer (FRP) products for repair and strengthening of structures since the late 1980s. FRP is the major component used in the construction of InfinitPipe, and the USDA-supported research focuses on the unique construction and feasibility as an impermeable pipe which can be made readily available for agricultural applications.

FRP Construction LLC, a specialty contractor that regularly finds itself in utility tunnels, under bridges and piers, under freeways, inside roadside culverts and much more, has achieved a significant and rare safety milestone: 4,000 days with no time lost from accidents.
A lost time accident is a U.S. Occupational Safety and Health Administration (OSHA) recordable incident in which an employee is not able to return to work or is assigned restricted work on the day or shift following the incident.
“Safety is a fundamental principle of our operations, and the methods we use to ensure safe work are addressed on each one of our unique installation projects,” says Adam Sedgeman, PE, MS, and Vice President of FRP Construction.
Founded in 2006, FRP Construction, LLC, specializes in repair and restoration of structures using Fiber Reinforced Polymer (FRP) products. These FRP products are supplied by a variety of manufacturers, including QuakeWrap, Inc.
Recent FRP Construction repair jobs include utility tunnels under the University of Arizona, freeway underpasses on I-17 for ADOT in Phoenix, cooling tower maintenance at the Palo Verde Nuclear Generating Station for APS, and steel bridge column repairs for the Indiana DOT.

The Arizona Department of Transportation (ADOT) recently announced it used carbon fiber strips that are “coated and strengthened with a reinforcing polymer” to fix girders on two state highway bridges in Phoenix. According to ADOT, one of those bridges is no longer listed as structurally deficient as a result.
QuakeWrap strengthening was applied to two bridges: The overpass at I-17 and Jefferson Street -- not considered structurally deficient – and the 19th Avenue overpass, which earlier had been labeled the most-traveled structurally deficient bridge in the state by the American Road & Transportation Builders Association. The bridge’s status has since been upgraded.
“Our ADOT Bridge Group focuses on using new and innovative bridge-repair technologies that enhance safety while saving time and taxpayer dollars,” ADOT Senior Bridge Engineer William Downes told Composites Manufacturing magazine. "We’re likely to use it again if and when repairs are needed.”

QuakeWrap, Inc. was proud to take part in a Joint Capability Technology Demonstration (JCTD) with the U.S. Transportation Command and U.S. Pacific Command (USPACOM). The demonstrations, in Pearl Harbor, Hawaii, involved U.S. Army and Navy divers implementing the U.S. Army Corp of Engineers PIER program. PIER allows for repair of a damaged structure within days instead of months, or even years, which in turn supports a variety of missions. Pier pilings were repaired with QuakeWrap's PileMedic product to demonstrate the equipment’s use in the field.
“This is a culminating demonstration of a two-week assessment of novel pier repair capabilities,” said Kawakahi Amina, an Operational Manager with PACOM Logistics, Plans and Exercises, in a public PACOM news release.
