The Trekr Design Erosion Control Mat © is made from discarded tires. The tires are cut in half along their circumference as one cuts a bagel in half. These are then joined in groups of seven by the use of stainless steel staples or hog-rings. The grouping in sevens creates a hexagon shape that can be joined to others as in a honeycomb pattern. This product solves two problems at the same time. It provides an excellent erosion control mat that will provide years of service at the same time as it reduces the number of discarded tires that are clogging our landfills.
