Safely Gain Access to Your Work Site Over Wet Ground Conditions with Swamp Mats

Signature Systems’ composite swamp mats create safe, stable surfaces for personnel and heavy equipment over mud, marshes, swamp land, and environmentally sensitive areas.

Construction mats for wetlands

Temporary Roadways for Heavy Equipment

Wet, soggy, muddy or marshy ground conditions increase the risk of expensive machinery and equipment getting stuck or damaged. MegaDeck® HD+ swamp mats safely support loads of up to 600 PSI over challenging ground conditions.

Environmentally Friendly Accessways

Signature’s access mats are made from non-toxic HDPE, which protects vegetation and environmentally sensitive areas from damage and controls soil compaction, preventing time consuming and expensive remediation efforts.

Reliable Swamp Mats for Heavy Equipment

Swamp matting provides non-shifting portable roadways that reduce the risk of accidents over challenging ground conditions. With reliable work surfaces, jobs stay on schedule, helping reduce project costs.

Signature’s construction mats for wetlands eliminate cross-contamination between worksites and the possible transmission of parasites, chemicals, oils, mold and insects. Mats will not rot or degrade, which allows for long-term installations with minimal environmental impact. After each use, swamp mats can be cleaned and reused on the next job site.

Benefits of Composite Swamp Mats

  • Lock-and-go, secure connection system provides safety, stability and quicker installations
  • Saves time and money on shipping with more mats per truckload than 3-plywood mats
  • Protects your equipment and minimizes wear and tear
  • Composite matting is available in a range of sizes and weight capacities
  • Composite mats are a sustainable solution that lasts up to 10 years, providing a significant ROI

30,000 sq. ft. Work Platform in the Backwaters of the Chesapeake Bay

MegaDeck HD+ swamp mats for heavy equipment were used underneath and on top of crane mats to create a work platform that supported a 400,000 lb. crane with 300 ft. reach, along with other heavy machinery during a transmission tower replacement project.

Heavy-duty Portable Roadways

MegaDeck HD+ construction mats for wetlands have overlapping flanges and an interlocking design that prevents differential movement between panels, ensuring a strong stable surface for over-sized equipment and vehicles.

Reusable Heavy Haul Mats

MegaDeck HD+ environmentally friendly composite swamp mats will not absorb or retain harmful chemicals or invasive species and can be used on multiple job sites for up to 10 years, providing a significant ROI.

Environmentally Safe Accessways

MegaDeck HD+ wetland mats created miles heavy-duty temporary roadway through otherwise impassible rain forest terrain. Located in an environmentally protected area, the project required the highest environmental and safety standards.
