Air Traffic Control

As air traffic increases year after year, airports find resources stretched to the limit as they try to maintain on time performance and most importantly, passenger safety.  In the realm of aircraft safety, nothing increases the coefficient of friction and reduces the likelihood of hydroplaning on both asphalt and concrete runways as effectively and inexpensively as grooving.  And nobody grooves as many runways as quickly and efficiently as Cardinal/International Grooving and Grinding of Conshohocken, Pennsylvania.

With over fifty patents in the grooving and related fields, Cardinal is the recognized leader the world over in airport grooving quality and production.  Designed in house, our SAFE-T-GROOVERSŪ all have 600 horsepower or more and some are capable of cutting 9-3/8 feet in a single pass.  Even our smallest piece of equipment, at eight feet, is two to three times as large and three to four times as powerful as standard industry equipment.  Our equipment is capable of grooving up to 2500 square yards per hour (depending on the type of pavement and aggregate) and we routinely groove 2,000 to 3,000 lineal feet of runway in a single day, in both asphalt and concrete!  In the last four years alone, Cardinal has grooved over 10,000,000 square yards of airport runways, more than any other company in the world.
