The United States Sports Surfacing Laboratory (USSL) provides professional testing services to both the U.S. and international marketplaces.
It was founded by Hans J. Kolitzus in 1989, to serve the growing demand for sport surface testing in the Americas.
Along with it's sister labs, Thomas Testing Inc., IST Leipzig GmbH in Germany, and Institut für Sportbodentechnik in Switzerland (ist-kolitzus.com), the USSL provides an expansive list of testing, developmental, failure analysis and expert services.
By design, we are not a mega-store, but a small Corporation dedicated to the needs of our clients and can work with you on a one-on-one basis.
