Would you want your high school your track team athletes to practice and compete on bare concrete? How about your football team, basketball team, baseball team, lacrosse team, soccer team. What athlete do you know that does this? Tennis players! The time for building safe play areas for our young tennis athletes has come.

I recently article on court surfaces in Tennis Industry magazine and was shocked that professionals in the sports and engineering field , experienced in specifying athletic fields and running tracks, with high end shock attenuation and force reduction qualities are promoting the virtues of bare post tension concrete when it comes to the sport of tennis. What about protecting tennis athletes and extending their time on the court.

Shoe companies shout the shock absorbing qualities of tennis shoes in cushioning the athlete....come on who really believes this is the really the effective answer? Are we loosing some of the better athletes in school because of unsafe facilities?

How many high school tennis athletes are damaged, careers in tennis shortened because of substandard facilities? What happens to athletes that regularly practice and play on concrete? Joints, backs, leg fatigue, diminished careers, knee trama, ankle swelling. The fast paced game played on these unforgiving surfaces jolt the body. Parents that scream for protection to their high school athletes in sports don’t consider tennis. The fast paced serve and volley game promoted throughout the US is not developing better tennis players but is injuring countless possible future players that could be bringing the game of tennis back in popularity.

Orthopedic Journal of Sports Medicine, 1/6/1018 commented “Overall, recurrent injuries resulted in greater time away from sport, a higher risk of sport discontinuation, and a higher likelihood of surgical intervention. In tennis, the repetitive nature of high-velocity arm movements causes overuse injuries in the upper extremity while the sprinting, stopping and pivoting, and pounding motions place repeated rotational shear and loading forces on each joint of the lower extremities which, in turn, places the athlete at increased risk for acute and overuse injury. "

The problem is not that we do not have the technology, we do. Tennis is the only sport played on everything from grass, clay, crushed rock, synthetic turf, asphalt, concrete, rubber, urethane cushion, plastic tiles, carpet. Hard courts speed the ball up, creating more force on the arm, and keep the bounce lower. A few coats of paint may be pretty but it does not make a surface safe for young athletes.

Our public and private schools are not considering child safety when choosing tennis court construction. Schools should consider what bare concrete does to a young athlete. This is not to say that post tension concrete is not a good base, it is but the tennis surface needs to be more than a coat of paint. These player unfriendly facilities put schools and children at risk.

Lets grow the game by taking aim at keeping our young athletes healthier, safer from injury and the long term potentially effects of joint trama so they can continue playing careers in both recreational and in competitive environments. Maybe the USTA can help in bring back tennis by emphasizing safer surfaces to keep the athletes safer. Perhaps the American Sports Builders Association should work on solutions in construction. Lets all of us address this for the betterment of the game and our future in tennis. Rick Burke, President NGI Sports

Birdbaths, depressions, or low areas on tennis courts are commonly defined as a low spot on the court that holds water. According to the ASBA (www.sportsbuilders.org), a birdbath is any area that water gathers and is held in a volume higher than 1/16” (2mm or the width of a nickel) for longer than an hour of drying in 70 degree Fahrenheit.

Depending on the severity of these areas, they could lead to delayed play and in the longer run mold or algae. The mold is a greater concern as it can either make play unsafe due to slick conditions, and even delaminate the acrylic on the surface. It is generally recommended to keep any court clean of such growth; power washing the courts is an effective action for mold removal.

These depressions could also be a result from improper construction or base preparation. Meaning that the courts could have been constructed using an improper slope, organic materials in the subsoil, improper compaction of the sub grade, or even bad drainage around the site. Over enough time most courts “settle” even with a perfect installation because of materials in the subgrade or site drainage issues.

There are 3 ready solutions for birdbaths, and they range in application and price. The cheapest option would be to apply multiple coats of an acrylic patch mix, once built up and flush with the surrounding areas and sanded smooth the courts could be painted. Next, you could tear out the court, or re-mill the asphalt giving a new surface. One of the most effective options would be to employ a modern day synthetic overlay system; they range in style, cost, and construction, but may also be the most cost effective. Depending on the court and its condition.

Continuing the discussion from last month on NGI’s 3D mapping for your job evaluations a way to start is:

1. Provide the layout of the courts by either sending an address for us to check on Google Earth, or send the image to us.
2. NGI will in turn send a court elevation sheet that matches that site along with any required instructions on where to start/stop the grid. This is especially critical if there are odd shaped court layouts or multiple batteries.
3. After the spreadsheets are returned we can create the 3D mapping data sheets and a report along with any recommendations etc.
4. We will gladly provide the report back to you under your logo. The cost to provide this service is $300.00/court. If the project is completed using one of NGI Sports surfaces we will deduct the costs from the materials invoice to you.

Please give us a call or email if you would like to discuss further.

Q. How long does it take to install an NGI systems tennis surface?

A. Installation time depends on the amount of preparation needed, weather, and system choice but usually between 5-7 days depending on site conditions.

Q. Are NGI Systems Tennis Surfaces glued down?

A. NGI systems tennis surfaces are free floating detached systems. The perimeter of the court is usually glued with an edge tape and in some cases a bead of glue to keep a clean edge transition for the surface and to prevent insects, dust, leaves etc from getting under the court.

Q. What kind of base do NGI Systems Tennis Surfaces need?

A. Most can be installed over a concrete, asphalt or any stable crushed stone or existing clay court base . This includes existing courts that are cracked and deteriorating. Each base must be inspected and prepared prior to installation of the surfacing system

Nagle spent last year and this winter visiting installation sites in process and completed projects before deciding to implement the TitanTrax Shield as part of their superior products line. David Burke met with the Nagle management and sales group to review details of the system. The 2020 selling season is in high gear with Nagle having sold 120,000 F2 of Shield with more to come.

Nagle Athletic Surfaces, is part of the Laykold team and exclusively uses Laykold color surfacing for their projects. As part of that team effort Nagle has pursued and gotten approval from the AstroTurf Cooperative Purchasing Program to approve the use of TitanTrax Shield surfaced with Laykold color surfacing for COOP purchasing. Any Laykold surfacing contractor can use the COOP to sell work to schools bypassing the public bid platform.

Nagle Athletic Surfaces employs in house crews and equipment for all of its projects. Ngi Sports is excited to be working with NAS based in Syracuse, NY, to further develop the New York, Pennsylvania and surrounding markets for TitanTrax Shield.

Since 1994, Sean Barry, owner and founder of Ace Tennis Surfaces LLC, has been working in the sport surfacing industry. He has done over 1000 commercial and residential courts and has worked with many different manufacturers on dozens of different types of surfaces. From asphalt or concrete, artificial grass or cushion, roof tops or basements, the quality and versatility of his work are unmatched. His expertise has not only taken him around New England but around the world.

Most recently, he was contracted to install a bank of 9 NGI Sports ProBounce Tennis Surfaces at Ripp Park in Waunakee, WI. This was a unique opportunity as the courts were installed over a crushed rock base. With the aging infrastructure at Ripp Park courts it was determined that grinding the existing asphalt on the courts and adding new base materials was the best solution for the rebuild. Ace has worked with NGI sports on similar projects in other parts of the country offering solutions for all weather courts with the “Overlay Renovation Technology” from NGI Sports.

When Sean is on site in different parts of the country he can be seen on his off time riding his Harley which travels with him. Often when his wife Jeanne joins him on the road they can be seen enjoying the countryside on his bike.

AllSport America Inc, has done business in N California and Nevada for the past 40 years. Part of their umbrella includes Sport Court Northern California and Boccee Builders of America. These operations focus on the residential backyard tile business for multisport applications and innovative bocce surfaces for both commercial and residential applications. Phil Park has been operating the business since 1979 and has successfully completed over 12,000 projects in his tenure.

Barrett Park, has worked at the business for most of his life from installing courts as a teenager to most recently managing sales. Recently the day to day operations of the business have been turned over to Barrett. Although Phil Park remains CEO of the company, working with Barrett as an advisor he has moved his focus to developing the bocce ball surfacing company named “Bocce Builders of America”. Barrett’s college sports experience and advanced business degree are now helping him to expand his core operations. He is expanding the operation to include a focus on NGI Sports “Overlay Renovation Technology”, building new and rehabilitating old tennis courts.

Expanding the focus of the core business to include the tennis court surfacing from NGI Sports, Barrett has hired, Lane Rutherford (from Oregon), to lead their NGI installation team. Lane has worked on projects across the USA installing the overlay systems and will allow AllSport to expand to install more successful projects. Presently, AllSport is working on 2 ProBounce tennis courts for a couple of high-end families, and has just secured a 2 court TitanTrax Air project for the City of Martinez, CA.

Barrett says ” Our team takes pride in our high-level of customer service and installation practices to ensure the client is taken care of from start to finish”. AllSport America is a Licensed General Engineering Company in both California and Nevada. Barrett Park is a Certified Tennis Court Builder, certified by the American Sports Builders Association.

Court Makers Inc. has been in the tennis industry since 1976. They have been steadily growing through word of mouth referrals as well as direct contracts with the South's most prestigious clients.

A family business, Marshall Dye along with his daughters Bridget Davis and Eileen Johnson and son in law Dwayne David, run the day to day operations. Marshall is an avid tennis player, golfer and hunter, but probably loves his family and 5 grand children more than anything.

Most Tennis players in the Atlanta area have probably played on a tennis court designed, constructed, lighted or resurfaced by Court Makers.

Marshall works closely with the ALTA community, swim & tennis clubs, private country clubs, schools, private home courts, apartment courts and public courts throughout Georgia. As a leader in tennis court design, construction, resurfacing, lighting and equipment supply, Court Makers top priority is getting the job completed on time and in a professional manner.

Marshall Dye and the Court Makers team strive to be innovators in the market. Marshall is a certified tennis court builder with American Sports Builders Organization.

10 Years ago Marshall heard about the new TitanTrax Shield crack renovation technology through NGI Sports being introduced into the tennis community. Marshall drove to Chattanooga to meet David Burke and see the product in person. In that one meeting Marshall requested to be the exclusive representative for TitanTrax Shield in the Atlanta Metropolitan area.

Court One was started in 1980 by two retired Navy officers in the Tidewater area of Virginia. They opened an office in Raleigh, NC to capitalize on the growth in the Triangle area of NC. In 1985, Gerry Wright purchased the NC operations with the idea of expanding Court One’s services of building and resurfacing hard tennis courts. Over the years Court One has expanded to two offices to better service our customers in NC, SC and VA.

Of course, a company’s success depends on the contribution of its management team and the competency of its crews. Vice Presidents Brian Wright (CTCB), Jon Wright (RA) and Branch Manager Rich Benson (past CTCB) guide the production crews and subcontractors. As a licensed General Contractor in NC, SC and VA, Court One oversees a variety of court and running track projects for both the public and private sector.

Not only has Court One expanded their office locations in North Carolina but also their services to include running tracks, clay courts, bocce, basketball, and pickleball. Court One was named “Builder / Contractor of the year by Tennis Industry Magazine for 2016.

Attracted by the challenge of constantly striving to provide a better product, Court One has embraced new technology and products that can provide customers more and better options for the repair of their courts. NGI continues to introduce innovative repair options. Now Court One not only does all weather tennis courts but has expanded their services featuring projects like NovaBocce courts at Carolina Arbors, cushion overlay systems like the new installation of 8 TitanTrax Xtreme tennis courts at the home of the 2016 mens state champion, Walter Hines Page HS in Geensborro, NC.

Court one Brian Wright also worked with the City of Charlotte and the Charlotte Hornets' Michael Jordon to provide TitanTrax Xtreme cushioned basketball courts for the inner city basketball program. “We are excited to bring the Hornets Experience to these three neighborhood courts in Charlotte,” said Hornets President & COO Fred Whitfield. “It is important to us to give back to the youth of our community, and we can think of no better way for them to show their love of both the Hornets and the game of basketball than by playing on Hornets-themed courts at their local parks. We also want to thank the NBA for demonstrating its continued commitment to Charlotte and Mecklenburg County by joining us in this effort.”

John E. Lineberry, established the Lineberry Tennis company in 1988, and turned Lineberry Tennis into a successful family-operated tennis company. Lineberry Tennis, based in Henniker NH, has been designing and installing tennis courts and recreational facilities throughout New England for over twenty-five years.

John’s background in tennis court construction goes back to summer work for NESCO, a tennis and sealcoating company located outside of Boston MA. John worked there while attending New England College on an athletic scholarship for ice hockey. John was Captain of the ice hockey team and graduated in 1973, as the 3rd all time scorer on the team. John, after graduating, continued to work full time at NESCO until 1977. John left NESC to join Pike Industries, one of the largest paving and construction companies in New Hampshire, as the company’s Tennis Division Manager. His background in tennis court construction includes full turnkey construction and surfacing of asphalt tennis courts and building clay courts as well as fencing and lighting amenities. John also managed the construction personnel and budgeting for the division.

This experience in design, installation, maintenance and consulting led to the opening of Lineberry Tennis in 1988. Lineberry Tennis traditionally works in New England and most of their maintenance and reconditioning contracts are in New Hampshire and Northern Massachusetts. In 2006, Lineberry Tennis acquired New England Recreational Services of New London, NH, thus expanding their client base and allowing for diversification of the company. Lineberry specializes in all-weather and clay tennis courts with an emphasis in specialty surfaces like NGI ProCourt and ProClay. They also install NGI putting greens, basketball hoops/key lines and NovaBocce courts.

John also was instrumental in the original testing and development of the patented ProClay surface with NGI. He assisted in the first clay court (a ProClay court) installed at the International Tennis Hall of Fame as well as the installation of ProClay at the Vestavia Country club in Birmingham AL with NGI and Welch tennis.

John’s son Johnny worked for Lineberry Tennis growing up and in the summers while attending Western New England College. Johnny also played ice hockey. He has traveled as well in winter months after graduation installing tennis courts in Hawaii. Johnny is an avid surfer going to Hawaii and Costa Rica honing his surfing skills on the world class waves. Hunting white tails and traveling are his other hobbies. Dirt biking around the Andes in Peru, staying in hostels and with locals are some of his travel likes.

In 2015 he acquired Lineberry Tennis from his father and is busy expanding the area of operation and product offerings. He installed the companies first TitanTrax Shield surface in 2019. John is also taking his company out of New England after the construction season closes there to do work on projects around the USA.

Let’s make sure we’re putting in court surfaces that keep our athletes healthy.

Would you want your high school track team athletes to practice and compete on bare concrete? How about your football team? Or basketball team, or soccer team?

Do you know which athletes do play on what is essentially bare concrete? Tennis players! The time has come to do something to change that, and to build safe play areas for our young tennis athletes.

I recently saw an article on court surfaces and was shocked that professionals in the sports and engineering field—experienced in specifying athletic fields and running tracks, with high-end shock attenuation and force reduction qualities—are promoting the virtues of essentially bare post-tensioned concrete when it comes to the sport of tennis. What about protecting tennis athletes and extending their time on the court? How many players, especially young players, is our sport losing to injuries caused by hard surfaces? How many high school tennis players have to quit, their careers shortened because of substandard or unsafe facilities?

Shoe companies constantly tout the shock-absorbing and cushioning qualities of tennis shoes. Sure, this may help lessen the impact with the court surface, but is this really the most effective answer to a playing surface that is essentially a concrete pad?

The fast-paced game played on these unforgiving surfaces jolts the body, wreaking havoc on joints, backs, legs and more. Parents of student athletes in all sports want their kids protected, but often, parents of tennis players don’t even consider the surface the youngsters are playing on regularly. An aggressive serve-and-volley game on hard courts may not so much be developing better tennis players than causing long-term injury to countless players, who may well have to stop playing altogether.

“Overall, recurrent injuries resulted in greater time away from sport, a higher risk of sport discontinuation, and a higher likelihood of surgical intervention,” according to the Jan. 6, 2018, edition of the Orthopedic Journal of Sports Medicine. “In tennis … the sprinting, stopping and pivoting, and pounding motions place repeated rotational shear and loading forces on each joint of the lower extremities which, in turn, places the athlete at increased risk for acute and overuse injury."

It’s not that this industry lacks the technology for softer court surfaces. Tennis is the only sport played on everything—grass, clay, crushed rock, synthetic turf, asphalt, concrete, rubber, urethane cushion, plastic tiles, carpet. Hard courts speed up the ball, creating more force on the arm, and keep the bounce lower. A few coats of paint may look pretty, but it does not make a surface safe for young athletes.

Often with court construction, our schools are not considering child safety and what bare concrete does to a young athlete. This is not to say that post-tensioned concrete is not a good base. It certainly is, but the tennis surface on top of the concrete needs to be more than what is essentially a coat of paint. These player-“unfriendly” facilities put children—and schools—at risk.

For the future of this sport, let’s all address this—court builders, facility managers, tennis coaches, teaching pros, the USTA, ASBA, TIA. We need to promote surfaces that keep our young athletes healthier and safe from injury, so they can continue playing tennis recreationally and competitively for their entire lives.

NGI Sports thoroughly recommends at this time of uncertainty that we all observe the recommendations of the government and health authorities to stay a safe distance from others and as much as possible stay home. Exceptions are shopping for food and other necessary supplies, work where unavoidable, but otherwise stay home, stay safe and see you all soon.

With all the challenges...

we are facing in the tennis construction industry managing time to get in and out of projects is more important than ever. Consider the TitanTrax Shield when beginning a crack repair project. Individual crack repair methods take 40% more time to complete than laying the shield over the entire surface if you have good weather. This means you get to the next job faster. TitanTrax Shield also has a five year warranty against cracking. The Shield protects the entire pavement from water, ice and sunlight oxidation making new cracks less likely to happen. Owners are never happy spending 12 to 15 thousand on a color and crack repair surfacing project only to have new cracks show up the next year. TitanTrax Shield is working smarter.

Did you know...

Bocce is closely related to British bowls and French pétanque, all having developed from games played in the Roman Empire. It was developed into its present form in Italy (where it is called bocce, the plural of the Italian word boccia which means 'bowl' in the sport sense), it is played around Europe and also in regions to which Italians have migrated. The popularity of the game spread first amongst descendants of Italian migrants but has slowly spread into the wider community.

Bocce is traditionally played on natural soil and asphalt courts. Bocce balls can be made of wood and various alternates and are spherical with no inbuilt bias. A game can be conducted between two players, or two teams of two, three, or four. A match is started by a randomly chosen side being given the opportunity to throw a smaller ball, the jack, and the Bocce ball is normally thrown using an underarm action. This is generally used to knock either the jack or another ball away to attain a more favorable position. Tactics can get quite complex when players have sufficient control over the ball to throw or roll it accurately. The United States Bocce Federation (USBF) says there are one million players in the USA and that Bocce is the third most popular game in the world after soccer and golf.

NGI Sports specializes in surfaces that provide optimum playability and cushioning properties. At NGI Sports material science is becoming one of the largest areas for innovation in tennis surface engineering and technology. Force reduction through cushioning and shock attenuation is not only an important property of a tennis court surface, it is also considered a key indicator of the performance, safety, comfort, and suitability of the surface for play.

A tennis player’s lower body is subject great stress and abuse through movements that create different forces on the lower extremities. Rapid stopping or foot planting creates some of the highest forces in tennis. There are frequent center of gravity adjustments where the body's center of gravity needs to be adjusted in any direction quickly and in a controlled manner, the direction of the forces placed on the foot and leg are forward, backwards, vertical as well as lateral. The body encounters more than just its own weight worth of forces from the energy returned from the tennis court. The surface therefore is important in reducing the impact of those forces to your lower leg and back.

As a designer and manufacturer of tennis court surfaces we use impact tests to measure and evaluate the effects surfacing design and surface design changes have on the impact forces generated on the body from the surface.

Testing results assist owners and players in making an informed, efficient, and empirical decision concerning a replacement tennis surface and for decisions regarding new surface selection. Puhulla et al (1999) defines hardness as “the ability of the surface to absorb shock imparted by the colliding object”. The most promising piece of equipment to measure surface hardness in the field is the Clegg Impact Hammer ®. This apparatus is an accelerometer device that relates to the deceleration of a falling weight on impact (Sifers and Beard, 1992; Neylan et al 1998).

We have conducted impact tests on numerous court surfaces. The impact forces simulated in the test method are intended to represent those produced by the lower extremities of a tennis player during play and impact on the tennis court. The Clegg machine fitted with electronic sensing instrumentation. Results are expressed in G Max values from 100 to 500. Benchmark figures for our use were based on concrete, asphalt and clay pavements.

In most cases clay (fast-dry) court play on courts two (2) to six (6) years old is thought to provide for a very comfortable and forgiving surface. Of course, the slide or foot release factor is not considered in this test. Results are based on an average of numerous sites tested with varying site conditions. Note that a larger numerical value reported represents less force reduction, a surface harder on the body.

These tests indicate a significant decrease in stress or advantage in force reduction for the NGI Surfaces. This appears true in all cases when compared to tennis courts built with hard pavement; thin cushioned finishes and as good as or better than clay courts in good condition.

We are continuing this study to build a database that compares the most prevalent courts in use today.
