Las Vegas general contractor leads the fight against Covid-19 with world’s first Opti-clean Cube


Las Vegas-based SR Construction, a full-service design build general contractor, is leading the fight against COVID-19 with the world’s first deployment of the Xtreme Opti-Clean Cube.

Produced by Xtreme Cubes Corporation, a manufacturer of modular buildings based in Henderson, Nevada, the Xtreme Opti-Clean Cube (XOCC) is a modular walk-through station designed to combat the spread of COVID-19, bacterias and other viruses.

Partnering with Proguardeum Corporation™, an environmental technology company, and Maddox Defense, providing human decontamination solutions, Xtreme Cubes has built the first mobile walk-through structure produced in the U.S. with an unobtrusive dry mist system of the Proguardeum™ solution that is safe on skin, clothing and requires no protective equipment to be worn.

Designed to be used at the entrances and exits to project sites, SR Construction ordered three Xtreme Opti-Clean Cubes when the concept was previewed to them in May 2020. The first unit was delivered to SR Construction on July 13, and has been deployed immediately at the entrance to a construction site at the 262-bed Centennial Hills Hospital Medical Center in Las Vegas, Nevada where they are building a new five-story patient tower. SR Construction employees, trade partners and site visitors will walk through the XOCC as they enter and exit the jobsite, helping to minimize the risk of infection on the project.

Bret Loughridge, president, SR Construction said, “The health and safety of our employees, sub-contractors and community is the top priority at SR Construction. We have served the Las Vegas valley since 1991, and we are proud to be working with other Las Vegas businesses to lead the way in combatting COVID-19 and other viruses and bacteria. We are the first company in the world to deploy the Xtreme Opti-Clean Cube solution, and look forward to introducing the cubes onto our jobsites, as well as leading the construction sector in utilizing this technology to keep our industry safe.”

Using proprietary and patented technologies to safely deliver an EPA and FDA approved hypochlorous solution (HOCL), the Proguardeum™ solution is produced at its highest purity in the form of hypochlorous (HOCL) without any contaminants, offering superior efficacy to inactivate 99.999%, a 5 log reduction, of known pathogens including COVID-19, and a long-standing stability for storage.  Proguardeum™ contains no additives, buffers or preservatives, and is pH neutral and is non-toxic and non-hazardous to people and surfaces. This eco-friendly solution helps to eliminate the spread of infectious surface and airbourne pathogens.

Equipped with motion sensors, the Proguardeum™ solution is applied as a person walks through the Xtreme Opti-Clean Cube. Measuring 8 ft. (2.43m) wide by 12 ft. (3.6m) long, each XOCC is equipped with forklift pockets meaning they can be relocatable or a permanent addition to existing buildings and facilities. The customizable structure includes options such as a thermal vision camera system. 

Part of the Ahern Family of Companies, owned by Don Ahern, Xtreme Cubes Corporation designs and manufactures custom modular buildings for a wide range of applications, including multi-family residential, office, retail, hospitality, military, industrial and agricultural.  

Brandon Main, CEO, Xtreme Cubes Corp., is proud that they have been able to work with other like-minded Las Vegas businesses during the COVID-19 pandemic. “We have been able to leverage our existing relationship with the Proguardeum team™ to create a perfect partnership, right here in the Las Vegas valley, to help develop a revolutionary solution that will not only benefit our local community but communities all across the world. The combination of Proguardeum’s expertise in disinfecting and our ability to rapidly design and engineer custom structures has been a winning formula, and I am delighted to deliver the first Xtreme Opti-Clean Cube to SR Construction, a longstanding and highly regarded Las Vegas general contractor.”

The XOCC is ideal for use at healthcare facilities, public buildings and events, such as casinos, retail stores, shopping malls, stadiums, entertainment and sporting venues, construction jobsites, offices, manufacturing facilities, and more. It was unveiled at the Xtreme Cubes corporate headquarters in Henderson, Nevada on June 3, and is now in full production.To learn more about the Xtreme Opti-Clean Cube, please visit or e-mail
