Leave a comment

The Hong Kong International airport HKG is home to the world’s busiest cargo gateway airport. In 2015, HKG moved over 4.38 million metric tonnes of air cargo.  It is also one of the world’s business passenger airports accommodating over 68 million passengers that same year.

Operations at the world’s busiest cargo airport run 24/7/365 without stopping. Maintenance crews need a crack and joint repair material that can be applied in a wide range of conditions and be ready for service in minutes. Roadware Flexible Cement II  is a tough polyurethane crack repair material that can be applied at any ambient temperature. It bonds very well to distressed concrete and forms a tough semi-elastic polymer that will withstand heavy airline traffic in about 15 minutes. Crews at HKG airport have relied on Roadware Flexible Cement II to make repairs whenever and wherever needed for over 5 years.

Dear Roadware,
“I am writing this letter in regards to Roadware Incorporated, in particular their 10 minute mender concrete repair product. I have been involved in the concrete industry for 28 years. I am a former Certified American Concrete Institute field testing technician and have been an ACI Concrete Flatwork Finisher and Technician for more than 10 years. For the past 15 years, I have been working to perfect the art of concrete rehabilitation on structural concrete and Architectural concrete. Other repair textures include masonry, slate. granite, clay artworks and architectural stone works.At the 2011 World of Concrete Convention, I met with The Roadware sales staff. I was quite intrigued and impressed with their 10 minute concrete mender product line. I was given some test samples which ultimately persuaded me into using Roadware product.
Our first project using Roadware products was a complicated repair contract with a bus transit authority and I had to include a two-year warranty. There would be limited time access during the repair and I needed a product that would withstand heavy bus traffic within hours of application. I submitted my bid using the specifications and MSDS for the 10 minute mender product line and believe this may have been the reason I was awarded the job. End result 10 minute mender works! Fractured concrete, spalled concrete, cracked concrete. Concrete deficiencies e.g. all surface and deep restoration repairs. Microdoweling works period! 

While I was confident in the product, it is always reassuring to experience it first hand. I am quite familiar with what it takes to provide world class service to demanding customers. Roadware Employees deliver excellent customer service and unmatched product support.”

Sincerely,

William F. Neal
