“Upon your completion of the 100,000 square yards of pavement grooving at the Buffalo Niagara International Airport and Niagara Falls Airport, I could not help but notice what a tremendously professional operation your firm provided. After some thirty-eight years of working in the construction business, I have yet to see a subcontractor perform as yours has. Your firm works at a speed second to none. A pleasure to see production and quality can still be achieved.”

“We were very pleased with your crew and the job they did for us. Their cooperation and experience helped bring in the job on time with just a minimum of punch list items. International Grooving’s portion of the project was run smoothly and brought in on schedule. If ever we are successful on another airport job, we will certainly contact you. Our highest recommendation goes with this letter.”

As you know, this was an emergency runway repair operation that consisted of timely scheduling and meticulous construction restraints. Everyone from the airport authority to the engineering firm commented on the outstanding job Cardinal Grooving performed. I look forward to future projects with you and I am happy to know there are still other companies out there who, like us, possess the “Pride in Work” philosophy.”
