Concrete Pumps are Used to Place Shotcrete

?????????????????????????

As part of our work on the 73 stories, 1,100 feet (335m) tall Wilshire Grand project in downtown Los Angeles, we will also be placing shotcrete for the vertical concrete in the subterranean levels.  Our crew will pump approximately 80,000 yards of concrete vertically, including lightweight concrete and 8,000 psi mixes using a Putzmeister Thom-Katt® TK 50 Trailer Pump.

An article from Shotcrete Winter 2014 Magazine, explains that the history of shotcrete dates back to the early 1900’s.  It was first developed as a technique used for taxidermy purposes by the founder of the Allentown Equipment Company, Carl Akeley.  He introduced a method of spraying plaster onto wire frames to create a thick coating that would not slump off, while at the same time, did not set until it was being placed.

It was not until 40 years later that the product we know as shotcrete was developed by Allentown Equipment who became well-known for their equipment and expertise in the industry.  The company was later acquired by Putzmeister in 2007, and in 2012, become known as Putzmeister Shotcrete Technology.

Over the years, the equipment and technology used to place shotcrete has continued to improve with the quality of pumps and selection of gunning machines available to do the job.  Some of the types of equipment used today include pre-dampeners, dosing pumps, combination mixer-pumps, mixers, chemical additive pumps and nozzle carriers to name just a few.

At The Conco Companies our fleet of modern, up-to-date trucks is complete with concrete pumps and all the necessary equipment needed to expertly tackle any shotcrete project.  Also all of our highly skilled, experienced nozzlemen are certified by the American Shotcrete Association (ASA).
