Pile repair spacers awarded U.S. patent


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.

InfinitPipe gets USDA boost for its sustainability, agriculture potential

( -- 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.

Arizona DOT uses QuakeWrap to strengthen, upgrade bridge status

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.”
