Polymeric running tracks are constantly bombarded with biological contamination from airborne sources, such as trees, grass, birds and also from footfall from sporting participants. This build up can cause the surface to lose its grip factor and become slippery. Spraying with a chemical to kill off the moss and algae spores will go some way to alleviate the problem, but the long term solution is to deep clean the running track and remove all the contamination. This process requires some specialist equipment such as the KBR system from Horger, http://www.sweepfast.com/index.php?webpage=deep_clean_polymeric.html and demands a large volume of clean water. However the end results are most spectacular and can transform the most unappealing surface into one which is a pleasure to look at and perform on with safety. To clean a full size running track will take a team about about 3 days to complete, and will most likely require chemical treatment 10 days prior to that. The image below clearly demonstrates the effectiveness of the KBRs ability to remove the contamination and restore an athletics track to its former glory.
