What is a dead-spot on a basketball court?
By: Paul W Elliott, PhD, PE Before discussing dead-spots, I want to briefly address field performance. If an architect, or owner, is concerned about the performance of individual installations, the specification must clearly state the performance levels that will be delivered and considered acceptable. Current North American specifications are vague and never state that the […]
Deterioration of an 8 year old Competitive NCAA Div-1 Track
ASET Services recently evaluated an 8 year old competition track at a Division I NCAA University. The title of this post includes the word ‘deterioration,’ and in some ways the track had deteriorated during 8 years. However visually the track was still flat it did not show excessive signs of wear, and the surface was […]
Turf Flatness and Sub-Base Problems
In many ways the most important part of a synthetic turf field is the sub-base. They control drainage and help maintain a flat playing surface. Owners and architects often take for granted that their installation will have a properly installed sub-base system. However, poorly installed sub-bases are more common than many realize and they lead […]
Performance Changes at a 10 year old Hardwood Practice Facility
Traditionally, architects and owners have assumed that hardwood courts maintain the safety, comfort and uniformity that was present at the installation for the life of the court. This is a summary from a study requested by the owner to determine if the high level of use had caused the performance of the floor to deteriorate […]
Head Impact Studies
I have been researching head injuries as they relate to Gmax and HIC testing over the past week or so. I was working on a paper for a client and needed to explain how HIC is related to head injuries and how the AIS injury scale can help predict the probability of different severity classes […]
A Tale of Two Reports
This article highlights differences between what we reported to a school with an aging turf field and the report from a firm that provided testing and inspections as well as provides maintenance and remediation services. ASET Services in a 3rd party test lab. What does that mean? It means we’re independent and we don’t manufacture, […]
Indoor Sport Surfaces: Area Deflection Requirements of Key Standards
This is the 3rd in a series of posts focusing with the requirements of key standards for indoor sports flooring. Globally Area Deflection is the most controversial property of sport surfaces. That is the very reason why the EU decided not to include it in their indoor multi-use sport standard (EN 14904). Area deflection does […]
Indoor Sport Surfaces: Vertical Deformation Requirements of Key Standards
Vertical deformation is one of the common properties used to specify the performance of indoor sport surfaces. Currently there are several standards that reference this property to define the comfort and performance features of indoor sports surfaces. ASET developed this document to help owners and architects compare the requirements of one standard to another. The […]
Indoor Sport Surfaces: Force Reduction Requirements of Key Standards
Currently there are several standards used to specify the comfort and performance features of indoor sports surfaces. ASET developed this document to help owners and architects compare the requirements of one standard to another. The information within this post may become dated in the future, however as of October, 2018 the data is still accurate. […]
Introduction to Synthetic Turf Fields
Several nearby schools have expressed interest in synthetic turf fields. Some of them reached out to ASET Services for more information. Over the past 6 months, ASET has developed an educational document that serves as an introduction to synthetic fields. It provides some general information about the lifespan, costs and benefits of a synthetic turf […]
