Contractors encounter a wide range of ground conditions on active job sites, and the type of mat they select can directly impact crew safety, equipment stability, and overall workflow. Heavy equipment access mats are essential for preventing rutting, protecting turf, and maintaining stability on soft or finished surfaces. But not all mats are designed to withstand the same weight. Understanding load ratings and how they relate to mat thickness, material, and intended use, is key to choosing the right solution.
Wright Environmental offers two types of access mats, each with distinct performance levels: ground protection mats and heavy-duty mats. Each product supports various types of machinery and ground conditions, and knowing the difference can help contractors avoid equipment damage, safety hazards, and costly downtime.
How Load Ratings Affect Safety and Equipment Performance
Load ratings determine how much weight an access mat can safely support without bending, cracking, or losing stability. These ratings matter because modern equipment, including compact loaders, skid-steers, tracked excavators, utility trucks, and bucket trucks, puts tremendous force on the ground beneath them.
Why Load Ratings Matter on Active Job Sites
- Preventing mat failure: Using a mat with a lower load rating than required increases the risk of breakage under pressure.
- Protecting machinery: An unstable surface can cause machines to tilt, shift, or sink, leading to mechanical stress or unsafe operating conditions.
- Increasing traction: Mats designed for heavy loads maintain a flatter profile, improving control for both wheeled and tracked equipment.
- Reducing crew hazards: Stable mats lower the risk of slips, falls, and equipment tipping, especially in wet or uneven terrain.
Comparing Ground Protection Mats vs. Heavy-Duty Access Mats
Wright Environmental provides two categories of mats with different performance characteristics. Understanding the differences helps contractors select the right option for each job.
Ground Protection Mats (Lighter-Duty Use)
Wright Environmental’s ground protection mats are designed to support compact and mid-size equipment while protecting turf, finished surfaces, and sensitive ground.
4×8 Ground Protection Mat
- Weight: ~80 lbs
- Load Rating: Up to 90 tons
- Best For: Equipment over 10,000 lbs, mid-size skid-steers, utility vehicles, and work trucks
- Advantages: Higher capacity with lightweight handling
3×8 Ground Protection Mat
- Weight: ~60 lbs
- Load Rating: Up to 50 tons
- Best For: Equipment under 10,000 lbs, landscaping equipment, small skid-steers, ATVs
- Advantages: Easy handling for tight or narrow jobsite access
4×8 Lite Ground Protection Mat
- Weight: ~60 lbs
- Load Rating: Up to 50 tons
- Best For: Equipment under 10,000 lbs, pedestrian walkways, turf protection, event flooring
- Advantages: Lighter alternative with strong performance on soft or finished surfaces
Heavy-Duty Mats (High-Capacity Applications)
Wright Environmental’s heavy duty mats are engineered for the most demanding load conditions and are built to support the extreme ground pressure created by cranes, excavators, boom trucks, and directional drilling equipment.
Heavy Duty Mat (13.1’ × 6.5’)
- Weight: 793 lbs per mat
- Load Capability: Supports high-capacity tracked and wheeled equipment
- Best For: Excavators, bucket trucks, cranes, large utility vehicles, and drilling and lifting equipment
- Advantages: Maintains structural rigidity under extreme point loads, reducing flex and preventing mat failure
How to Select the Correct Mat Based on Equipment Weight
Choosing the right mat begins with accurately assessing the weight of your machinery, but not just the “operating weight” listed by equipment manufacturers. Ground pressure varies depending on how equipment is used, where it's placed, and what attachments or loads it carries.
Key Factors to Consider When Selecting a Mat
- Equipment weight with attachments: Buckets, augers, grapples, and other tools significantly add to the overall equipment weight.
- Load being carried or lifted: Material loads increase surface pressure dramatically.
- Ground conditions: Wet, muddy, sandy, or thawing ground requires more supportive mats.
- Point loading: Outriggers, jack pads, and track edges concentrate weight into smaller areas, resulting in a more concentrated load.
- Traffic frequency: Repeated passes over the same path require mats with higher structural strength.
Choose Ground Protection Mats When:
- Equipment weighs under 10,000–20,000 lbs
- The ground is soft but not deeply saturated
- Protecting turf or finished surfaces is the priority
- Lightweight mats improve installation speed
- Applications include landscaping, walkways, utility carts, or mid-size skid-steers
Choose Heavy-Duty Mats When:
- Operating cranes, excavators, boom trucks, or high-pressure tracked equipment
- Outriggers or stabilizers are used
- Soil is saturated, unstable, or deeply rutted
- The job requires months of repeated use
- You need mats engineered for extreme point loads and heavy industrial conditions
(Heavy-duty mats provide thick, rigid support designed for the highest-weight equipment.)
