Isotrack mats can be shown to strongly support project sustainability objectives, and also result in project cost savings. Compared to traditional methods like gravel or steel roads, our mats are made of recycled plastic, are durable with long life, require less transport, require no or minimal ground preparation, are quickly and easily installed with minimal habitat impact, provide a safe working surface, and are fully recyclable at end of life. They are easily cleaned for reuse across multiple projects, supporting a circular economy. We will also present case studies where Isotrack mats were selected over traditional temporary access options to deliver more sustainable projects.
