Innovative Engineering Design for Superior Performance and Durability
MegaDeck HD construction mats are manufactured in the United States using a proprietary blend of High Density Polyethylene (HDPE) and special impact modifiers to accommodate thermal expansion, UV resistance, anti-static properties, and tremendous strength. A unique process ensures all plastic is completely melted then molded, preventing micro-fissures and inconsistencies. A hollow ribbed interior provides superior performance over soft ground with a low California Bearing Ratio (CBR).
The world’s strongest construction mats are fully modular and can be interconnected in multiple directions to form large work areas, passing lanes, turns, and a variety of other platform and roadway configurations. These rugged composite mats will not rot, degrade, or warp, which allows for long-term installations and many years of reuse.

- Quick lock-and-go connections
- Save time and money on shipping with more mats per truckload than 3-ply wood mats
- Protect your equipment and minimize wear and tear
Overlapping Flanges Make Installation Fast and Easy
MegaDeck HD’s dual-sided design allows for ease of installation and versatility. Mats are laid together seamlessly due to their 12 inch flanges, which guide the mat into place. Once in place, mats are locked together to form a solid non-shifting surface.
This heavy-duty overlapping flange system allows adjacent mats’ flanges to nest for additional strength and rigidity. MegaDeck HD is strongest at its connection points, and the small space between mat surfaces helps to direct rainwater runoff.

Safer Working Environment with Optimized Traction Pattern
MegaDeck HD access mats feature an optimized anti-slip traction pattern, molded into the top surface, that allows personnel, vehicles, and tracked equipment to work safely in any environment or terrain.
MegaDeck HD Works Where You Work
MegaDeck HD composite rig mats are designed to be used with no ground preparation over grass, gravel, soil, concrete, asphalt, mud and sandy soil conditions. However, it is recommended that terrain be filled and smoothed as much as possible and that a geotextile barrier be used in wet and/or hazardous situations.
Protect the Environment and Prevent Cross Contamination
MegaDeck HD is an environmentally-friendly composite mat that will not absorb or retain harmful chemicals or invasive species, and thus will not transfer contaminants to other jobsites or storage facilities. The MegaDeck HD non-toxic material protects vegetation and will control soil compaction, saving costly reconstruction efforts afterward.
