Don’t let unstable ground protection slow you down – choose Grassform’s heavy duty access mats and move forward with confidence!
Ultra-strength with versatile applications across industries
Our premium heavy-duty composite mats are designed to handle the most challenging loads, supporting up to 252 tonnes of force. This exceptional strength and durability make Grassfrom HD Overlap ideal for a variety of industries, including construction, transmission, portable accommodation, events and sports, and many more.
Whether you’re managing a construction site or creating stable surfaces for pedestrians, Grassform composite mats excel in the most demanding of environments and weather conditions, while ensuring your operations proceed smoothly and safely.
Innovative dual-sided design
What sets our heavy-duty composite mats apart is their versatile dual-sided design. One side features a robust traction surface, perfect for vehicular traffic. The other side is pedestrian-friendly, ensuring safe foot traffic. This dual functionality allows for a wide range of applications, from creating secure access routes to providing safe walkways in high-activity work zones.
Secure and seamless connections
Grassform HD Overlap ground protection boards feature an advanced overlapping flange and integrated locking system, creating a seamless, trip-free surface even in challenging conditions. This secure connection system prevents mat shifting under heavy loads, enhances overall site safety, and reduces the risk of damage to both the mats and the underlying grass or ground surfaces.
Environmentally responsible choice
In addition to their impressive strength and weather resistance, Grassform HD Overlap mats are also chemically inert and 100% recyclable. These qualities make them ideal for use on sensitive grounds and eco-sensitive areas, such as Sites of Special Scientific Interest (SSSI). By choosing Grassform HD Overlap, you’re not only investing in quality but also reducing your environmental impact.
