SDI continues to be a leader and innovator in the field of manufacturing products from post-consumer recycled tire rubber. We use 10 mesh minus crumb rubber or buffings according to the requirements of the product. Our environmentally conscious products will meet your traffic and safety needs,

will not crumble, flatten or break, and are resistant to the elements.
