Concrete Grinding & Grooving

Removing imperfections and enhancing the safety and ride of roadways and runways, that’s what our diamond grinding and grooving services are all about. Penhall can provide every concrete solution you need to complete your project on time, on scope, on budget, and most importantly, safely.

DIAMOND GRINDING

Concrete diamond grinding removes roadway imperfections caused by construction and/or heavy usage. The immediate result is an improvement in pavement smoothness, surface texture, skid resistance, safety, and noise reduction. This service can also be applied to asphalt pavement.

Advantages of diamond grinding over other rehabilitation techniques:

  • Costs are reduced versus other rehabilitation techniques.
  • Work is usually conducted during off-peak hours, which shortens lane closure times and minimizes encroachment into adjacent lanes.
  • Fewer lane closures, as diamond grinding in one lane does not require grinding of adjacent lanes which may have acceptable surface characteristics.
  • Smoother ride for all vehicles, better skid resistance when braking, and increased fuel economy due to less rolling resistance.

    Next Generation Concrete Surface (NGCS)

Penhall also provides Next Generation Concrete Surface (NGCS), which is a newer concrete texture designed to provide a substantially quieter and safer driving surface. The process starts by conventionally grinding the existing surface and then removing the corduroy texture left by conventional grinding. Lastly, the concrete surface is grooved longitudinally to provide the negative texture that has been proven to be the quietest concrete pavement surface in use today.

At a post-project completion open house, at which Penhall displayed a PC-6000 diamond grinder, local mayors raved about the reduction in the amount of noise coming from the adjacent freeway.

One mayor described how he could, for the first time, have a game of catch with his son in his backyard without yelling to be heard.

A TxDOT report on the project claimed the noise reduction after the NGCS application was equal to a 72% reduction in traffic.

    Corrective / Profile Grinding

Penhall’s corrective and profile grinding services reliably correct pavement that has been found to be out of spec, or which has experienced a failed ride test. For clients that need surface testing or re-testing, Penhall owns and operates profile testing equipment that uses the latest in pavement surface testing laser technology. After the testing-for-ride is performed, our highly trained and experienced team can also help clients evaluate the results.

Concrete diamond grinding is also often performed alongside other concrete pavement preservation and restoration (CPP / CPR) techniques, such as:

  • Full- and partial-depth repair and spall repair
  • Cross stitching
  • Dowel bar retrofit
  • Slab stabilization
  • Joint / crack resealing

DIAMOND GROOVING

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 or longitudinally into the surface.

Concrete grooving provides 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 configuration and specification requirements for newly constructed or rebuilt bridge decks.

  • Improved drainage
  • Faster pavement drying time
  • Increased friction

AIRPORT RUNWAY GROOVING

We can service multiple runways in a large airport simultaneously, so they can return to operation quickly and our clients can conserve costs.

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.

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

TESTIMONIALS

Often when Thompson has used Penhall it has been in an outage situation where safety, timing, and production are paramount. Penhall has always successfully completed the work on time and within the agreed upon budget.  They have a meticulous attention for detail, a great regard for safety, and are readily available and willing to answer any questions. With their numerous years of experience, they were more than capable of thoroughly handling any problems that arose. 

 

In my opinion, Penhall would be an excellent choice to be considered as a critical team member of any industrial construction project.

Penhall Company has always been on the leading edge of technology, this (digital x-ray) is just one more example.

I contacted [Penhall] for 2 floor scans on [a] 5th floor room. [They were] able to come and complete the work needed by [the] afternoon. We thank Penhall for always being accommodating for our project success

The scan done of our existing slab saved both the owner and myself money and headaches. The scanned lines were undocumented power lines for future expansion. If we would have hit those lines it would have been a mess and would have not only cost our project money, but also the project in the future that is planned for those lines. Thank you for what your team did.

The work performance of Josh, Henry, and other crew members has been exceptional.   The crew arrives on time and prepared to work.  The Penhall crews have met or exceeded expectations during their time on the project.  I was fortunate enough to witness several operations, including the rebar scanning, which turned out to be a new learning experience for me.  Karina took the time to teach me how the rebar scanning device worked.  In addition, Penhall crews assisted with resolving any unknown issues that presented a challenge.  For example, Henry played an active role in resolving issue of avoiding rebar during the coring operations and minimized any potential impacts.   

 

 The communication efforts between BZJV staff and Penhall demonstrated true partnering between contractor and sub-contractor and to the success of all.  I personally enjoyed working with Penhall and look forward to continuing the working relationship in the future.

Just wanted to drop you and your team a line of appreciation on the great service Penhall provided on the bridge deck grinding needed for our project.It truly was a pleasure working with Penhall glad the company keeps the people that help them be successful from state to state. Thanks again for your service.
