Beynon Sports is the world leader in manufacturing polyurethane running track surfaces. Their resume of world class installations is unparalleled. Beynon Sports is also on the forefront of manufacturing environmentally safe products including their waterborne spray coatings. Their pore sealer for impervious sandwich systems is a thixotropic two component polyurethane. Some other manufacturers still use dated technology that requires covering the surface with rubber dust to fill the pores. As these surfaces wear the dust dissipates causing the surface to become permeable. The resurfacing cost of a track built with the dusting method will typically cost the owner an additional $40,000.00 to $80,000.00 in order to re-seal the surface. Typically, the Beynon sandwich style track systems have a thicker wearing surface than the competition. In some cases, the wearing course is 40% thicker resulting in a longer life.
