The M5 mat is a series of holes surrounded by fully vulcanized latex, or latex/Nitrile mix. It is flexible, hardwearing and long lasting. The holey mats (Or ring mats, honeycomb grass protection mats) come in two sizes and two grades. The honeycomb mats are ideal for allowing new grass growth on poached areas, reducing mud in heavily used gateways, creating slip free pathways, grass protection, or for containing gravel. Because the honeycomb grass protection mats (Ring mats) are flexible, they can be laid straight onto existing grass, or hard standing with no pre-preparation. They are totally non slip in any weather making them ideal for use as muddy gateway mats.
