Commentary Player Safety & Post Tension Concrete in Tennis Court Construction

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

Ask The Expert


Do you have any questions about any of NGI’s products, processes or anything industry related? Please email for answers or visit our website.Q. Will Sand Infill Be Moved Around During Play On The NGI Systems Synthetic Grass Courts?


A. No, the synthetic turf fibers form a matrix which keeps sand from migrating or becoming washed out of the surface.

Q.Will the Infill Wash Out When It Rains?
With the proper design slope, the majority of the rain will drain across the surface with any residual water draining horizontally through the surface. On our artificial grass systems, some moisture will percolate vertically down to the base.

Q. Will the Color Fade In the Hot Sun?
The special Thiolon yarn is produced with a very high resistance UV inhibitor to preventand/or minimize fading.

Q. What Are The Maintenance Requirements For The Courts?
A. Once our NGI Systems Tennis Courts are installed, they require a check-up and periodic cleaning as well as grooming, depending upon the type of court and amount of play it receives.

Q. Is The Expected Life Of The Surfaces?

A. The expected life on any of our surfaces, with proper maintenance, is up to 20 years. This gives a reasonable surface-life that equates to an excellent sports investment.

Client of the Month: General Acrylics, Inc.


General Acrylics, Inc. was incorporated in 1958 in the State of Arizona under the name of W-H Construction, Inc. By the early 1960’s the company responded to the growing demand for tennis court construction and all-weather track surfacing. By 1972 the tennis court and track construction division had grown to the point that it was split off and named General Acrylics, Inc. In 1987 the current owner, Jonnie Deremo, purchased 100% of this division of the company and its stock.

General Acrylics, Inc. is currently headquartered at 22222 N. 22nd Avenue, in Phoenix, Arizona with an office and warehouse of approximately 11,000 square feet in size. They install both latex and polyurethane track surfaces and in 1998 began installing synthetic turf.

Since 1987, General Acrylics, Inc. has become the leading tennis court, track and synthetic turf contractor in Arizona and the entire Southwest region. Their motto “See the Difference” signifies their commitment to providing reliable products and quality installations. Jonnie Deremo has always ensured that General Acrylics is a leader in the sports construction industry by continuing to develop innovative products, applications and construction methods.

Jonnie grew up in a small farming town in Southwestern Colorado. He was raised working on the family farm alongside his father from a young age–an experience that laid the foundation of his relentless work ethic and entrepreneurial spirit.

When he was 8 his parents made the decision to move to Arizona part time so that that he could attend school in the valley, where he graduated from Moon Valley High School, he then attended Glendale Community College and completed classes in estimating as well as blue print reading and drafting. During school he realized his passion lay in owning and running a business of his own.

In 1982 Jonnie left the farm to race motocross professionally around the country. In 1984 he started a service business which he later sold looking to get into the construction industry. His search led him to General Acrylics. With his athletic background, sports construction struck a chord and in October of 1987 he purchased the business from it’s founder, Dick Hoover. From that point on Jonnie worked tirelessly to grow General Acrylics into one of the premier sports facility construction companies in the U.S.

General Acrylics has been a long-time member of the American Sports Builders Association and Jonnie is an ASBA certified tennis court and running track builder.

When not in the office Jonnie spends most of his time outdoors riding dirt bikes, mountain biking, fishing and spending quality time with his family. He still spends a large amount of time in his former home state of Colorado.

NGI Sports patent pending TitanTrax PK pickleball court surface is the only surface specifically designed for pickleball to achieve the perfect ball response for all players.

3D Mapping for Contractors

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.
