The Rooster Tail! Spray of black rubber.

It may look dramatic in slow motion replays, a spray of black rubber erupting behind a tackle or a hard hit ball. But the “rooster tail” is not something we want to see from a well designed turf system. When there is too much infill in the turf system, the material becomes highly mobile. That leads to: Inconsistencies across the field as infill migrates from one area to another Uneven playing…

Rethinking Ball Roll Testing in Soccer

Ball roll is one of the oldest tests we still use to evaluate playing surfaces. But do we ever stop to ask if it really reflects the game of soccer? The method dates back to the 1930s when it was developed for golf greens. Over the decades it has been adapted, and in many ways bastardised, into soccer testing. While the test has some merits, it should never be mistaken as…

The Limits of Pile Height as a Defining Property for Turf

The Limits of Pile Height as a Defining Property for Turf In many discussions, turf systems are still defined by pile height, or more accurately pile length. While length is an important parameter, it is far from the sole determinant of turf functionality and, in many cases, not even the most influential. A turf system’s suitability for a given application arises from a wide set of interrelated properties that together shape…

Surface Temperature ≠ Heat Stress

During summer, the importance of surface choice in managing heat stress is more apparent than ever. Well-maintained natural grass remains the gold standard for thermal comfort. Its ability to cool itself through evapotranspiration, combined with high surface reflectivity and low thermal mass, provides a naturally regulated environment for sport and outdoor leisure. However, not every field can be irrigated or maintained at this level. To understand heat stress, it is important…

Enhancing Urban Health Through Green Spaces

In densely populated urban environments access to play, sport and recreational spaces is not merely an aesthetic enhancement but a critical component of public health. Research consistently demonstrates that outdoor environments contribute to reduced stress levels, improved mood, and enhanced physical well-being. Turf surfaces in particular offer a sustainable and accessible solution to the scarcity of green spaces in urban areas. By providing safe, inviting, and functional outdoor environments, turf surfaces…

From Mud to Mastery: The Transformation of Natural Grass Pitches

Over the past 30 years, natural grass football fields have undergone one of the most remarkable transformations in modern sport. In the 1980s and 1990s, even top-level stadiums regularly featured surfaces that were muddy, inconsistent, and unpredictable. Matches were often shaped as much by divots and ruts as by tactics and skill. It was common to see standing water in goalmouths, bare patches across midfield, and players sliding through thick mud.…

When the Fields Are Closed, Everyone Loses

Fields provide one of the most valuable and accessible opportunities for people to play, move, and connect. But too often, they are closed when people need them most. Whether it is due to poor conditions, lack of maintenance, or limited water availability, natural fields are frequently taken out of service. When a field closes, the lost time cannot be recovered. Missed games, cancelled practices, and unused play hours mean fewer opportunities…

Critical Fall Height & HIC: The Test that protects us

A child drops from the top rung of a climbing frame. A footballer is driven hard into the turf or grass in a last-ditch tackle. In both moments safety, injury, and risk are decided by the surface below. We engineer those surfaces and extensively test our products so the story ends with a quick smile, not lasting harm. 📊 The Science Critical Fall Height (CFH) – The highest point a person…
