The purpose of concrete grooving is to improve vehicle traction and reduce roadway accidents. By cutting patterned groves into the concrete deck, water is displaced, thus reducing the risk of hydroplaning and improving vehicle control and overall safety. Penhall’s grooving machines use diamond-tipped saw blades to cut grooves transversely into the surface. The blades are constantly cooled by water pumped from a tanker and are equipped with highly-efficient vacuums
Concrete grooving provide a variety of enhancements to roadways and highways, including:
- Improved drainage
- Faster pavement drying time
- Increased friction
Bridge Deck Grooving
While hydroplaning on a roadway is dangerous in and of itself, hydroplaning on a bridge greatly magnifies that danger. Bridge deck grooving is an effective method for reducing weather-related bridge hazards. Our team of professionals can also assist you in meeting your state’s particular configuration and specification requirements for newly constructed or re-built bridge decks.
Airport Runway Grooving
Penhall can provide every concrete solution you need for your next airfield job and our reliable airport runway grooving services meet the Federal Aviation Administration’s (FAA) recommended specifications for transverse-grooved cut dimensions.
We use state-of-the-art tools and processes to achieve unmatched consistency and quality of work. Diamond-tipped saw blades are mounted side-by-side on our high-production machines to deliver perfectly consistent runway grooving that maximizes aircraft traction. Proper grooving also helps to eliminate the risk of hydroplaning and other deceleration complications caused by severe weather conditions, resulting in shorter braking distance of aircraft on wet pavement.
Penhall’s skilled and experienced team has the capabilities to service multiple runways in a large airport simultaneously so runways can return to operation quickly and our clients can conserve costs. Never gamble with passenger safety by neglecting maintenance, or choosing a sub-standard contractor to complete your work.
The FAA has observed that transverse-grooved surfaces offer many positive outcomes:
- Drastically reduces all types of skids on wet or flooded runways
- Provides positive nose-wheel steering during landing roll-out
- Prevents the onset of drift and weathervaning
- Improves overall ground handling and stopping characteristics of aircraft
- Prevent the onset of drift at touchdown in flooded areas due to high cornering forces
Rumble strips are among the most cost-effective road safety features available and Penhall is proud to have the knowledge and capabilities to expertly install them. Rumble strips alert drivers that they have strayed off the travel lane and assist in determining lane limits when inclement weather conditions reduce driver visibility.
The Penhall team employs state-of-the-art equipment to quickly and efficiently cut continuous shoulder rumble strips (CSRS), centerline rumble strips (CRS), and transverse rumble strips (TRS) into both concrete and asphalt. Our machines also use water to control dust, a powerful blower to disperse ground-up concrete or asphalt into grass, and a special cutter head configuration that can be modified to meet specified strip widths.
