Artificial Turf History: Early Beginnings of Synthetic Grass
The common belief that synthetic grass was developed specifically for the Houston Astrodome in 1965 is a misconception. To understand the full story, we need to look back further. Originally created to replace concrete and brick, synthetic grass was intended to bring green spaces to city schoolyards.
During the Korean War, the U.S. Army observed that urban recruits were less physically fit than their rural counterparts, and identified the lack of green areas as a potential cause. The Ford Foundation funded research by Monsanto to develop a synthetic grass replica in 1962, aiming for a wear-resistant, cost-efficient, cushioned, and traction-tested surface. Two years later, employees from the Chemstrand Company, a subsidiary of Monsanto, fulfilled this ambition by introducing “ChemGrass.”
This innovative synthetic surface was first installed at the Moses Brown School in Providence, Rhode Island. While the new product met all the original criteria outlined by the Ford Foundation, it was expensive to produce, making it unsuitable for inner-city playgrounds. However, this setback led to a new beginning for the product and a fresh name.

1960s – 1970s: First-Generation Turf a.k.a. Astroturf
In 1965, the Houston Astrodome made history as the first domed stadium with a glass-covered roof, allowing real grass to grow inside. However, the glass caused a glare that made it difficult for athletes to track the ball. Attempts to paint the glass resulted in the grass dying.
In 1966, Houston introduced ChemGrass, later known as AstroTurf®, as a solution. The initial iteration, was far from the lush, realistic surfaces we see today. Astroturf was made from coarse nylon fibers, offering durability but lacking the natural look and feel of real grass.
The drive behind the development of early artificial turf was the need for a low-maintenance, all-weather playing surface for sports. It was a response to the limitations of natural grass, which required extensive care, suffered from wear and tear, and became unusable in inclement weather. Astroturf, although not perfect, provided a significant improvement in these areas. However, its abrasive texture led to concerns about athlete injuries.
This artificial turf revolutionized sports and became popular in stadiums worldwide. Despite its initial drawbacks, AstroTurf® has provided a durable and consistent playing surface for athletes, hosting numerous iconic sporting events, such as:
- 12 World Series
- 11 Super Bowls
- 10 Olympics
- 8 Major League All-Star Games
- 32 NFL Pro Bowls
It has become the preferred surface for stadiums worldwide. However, the first generation of artificial turf posed challenges such as joint problems, player injuries, and material deterioration. Over the years, advancements have been made to improve artificial turf for better performance and player safety.
Astroturf marked the birth of synthetic grass and served as the foundation for future developments. Its introduction brought about a significant shift in sports facility management, allowing for year-round play. However, it had its drawbacks, including a hard and abrasive texture that led to increased injuries among athletes.
Over time, the desire for a more natural look and feel, as well as enhanced safety, drove further innovations in the world of artificial turf. The influence of athlete feedback, coupled with advances in materials and manufacturing technology, played a crucial role in shaping artificial turf history and the ongoing evolution of synthetic grass.
1980s – 1990s: Second-Generation Turf
The second-generation synthetic turf was first invented in 1976 by Frederick T. Haas. The 1980s and 1990s were a time of significant technological progress in the artificial turf industry. With increasing demands for better performance and player safety, manufacturers began creating more advanced turf systems. These surfaces included a shock-absorbing pad beneath a carpet with much longer fibers compared to the first-generation systems.
One important development during this period was the introduction of infill systems. Instead of relying solely on the turf itself for cushioning and support, an infill material was added. The carpet pile was filled with silica sand, which filled the spaces between the turf fibers, allowing them to stand upright. This innovation greatly improved shock absorption, reducing the risk of player injuries, particularly in high-impact sports like football.
Additionally, the materials used in artificial turf underwent significant enhancements. Second-generation turf systems featured longer and softer fibers, making the playing surface even more similar to natural grass.
While this second-generation artificial turf worked well for sports like field hockey, it did not replicate the behavior of natural grass for football, baseball, and lacrosse. Not only did the ball not behave “right,” but it also caused painful abrasion injuries from the sand. In the early 1990s, many sports stadiums switched back to natural grass playing fields. However, issues persisted with natural fields, such as challenging maintenance and the need for abundant sunlight.
2000s – Present: Third-Generation Turf
Third-generation turf surfaces involve filling the space between vertical pile fibers with a granular material, creating an infilled system. These systems use infill materials such as crumb rubber or a combination of crumb rubber and silica sand, unlike the pure sand used in second-generation systems. The initial third-generation system was created by FieldTurf and was first installed in 1997 at a Pennsylvania high school. Subsequently, multiple companies have produced similar products.
The most recent iteration of sports turfs provides an exceptional playing surface that exceeds all previous versions. Thanks to revolutionary advancements in materials, artificial grass blades have become softer and less abrasive. Combined with high-performance backing materials, these modern sports turfs are specifically engineered to meet the unique requirements of every major sport.
Third-generation artificial turf fields now provide improved safety, playability, appearance, and durability, with lower operating costs and reduced annual maintenance needs. These fields are used more frequently than natural grass fields due to their lower maintenance requirements, making them suitable for use even in unfavorable weather conditions.
Maintaining synthetic grass is easy, which is why many universities and professional teams are opting to install it once again. The new, 3rd generation sports turf brings significant enhancements. The grass blades are taller and spaced farther apart, allowing players to dig their cleats deeper into the turf. This reduces strain on joints and gives athletes better traction and performance.
Furthermore, the use of polyethylene instead of polypropylene has resulted in softer and less abrasive blades. Tackles can now be executed comfortably, without the concern of skin abrasion. With the introduction of these advanced sports turfs, athletes can now play at higher speeds with reduced risk of injury.
