The Benefits of Reusable Construction Entrance Mats Versus Rock

Written by Signature Systems | April 14, 2025 at 3:29 PM

Construction is a tough industry with very specific requirements. Clean site access is critical to maintaining safety, efficiency, and environmental compliance. The standard method for clearing dirt and debris from vehicle tires as they leave the site has been to use rock trackout pads, which are essentially rock-filled construction zone exits. However, more recent options offer better results at lower costs and an added advantage of environmental care.

What are the top 3 advantages of reusable construction exit mats compared to traditional rock trackout systems?

Unlike traditional rock pads, reusable composite mats have a long lifespan of up to ten years, require no replacement, and require very little maintenance, which lowers long-term costs significantly.

The three primary advantages are:

  1. Affordability
  2. Durability
  3. Ease of Maintenance

They also guarantee better compliance with environmental standards and offer superior sediment removal, avoiding potentially expensive fines.

 

The Challenge of Traditional Rock Trackout Systems

Rock trackout pads have been the default choice for decades. So, what are rock trackout pads exactly? They consist of large, angular rocks laid on top of a geotextile fabric to stabilize the exit point of a construction site. 

When vehicles pass over the rock pad, mud, dirt, and other debris are expected to fall off the tires and remain on-site. Unfortunately, the effectiveness of this method depends on several factors that are often out of workers’ control, such as: 

  • rock depth
  • vehicle size
  • the number of vehicles passing through

Traditional rock trackout systems can cause several issues. Some of the primary problems associated with their use are:

  • High Maintenance Costs

Over time, the rocks in these trackout pads compact, and dirt builds up on the surface. These types of trackouts need constant turnover of the rocks to maintain their effectiveness, as well as frequent replacements, which is not the greatest when it comes to efficiency. 

  • Environmental Impact

Rock trackout pads frequently fail to keep all debris from exiting the site, which allows soil and other pollutants to reach neighboring public roads and waterways, causing harm to the environment and possibly incurring fines.

  • Labor-Intensive Cleanup

Once a project is complete, removing the rocks used for this method and cleaning up the site requires significant labor and time. Using rocks is costly in terms of manpower and potential delays in project timelines.

  • Inefficiencies

Despite these efforts, rock trackouts still leave construction sites susceptible to fines and penalties due to environmental violations, especially under the Storm Water Pollution Prevention Plan (SWPPP).

Looking at Reusable Construction Exit Mats

DiamondTrack reusable construction exit mats offer a cutting-edge solution to the problems posed by traditional rock systems. These portable composite mats have a special diamond-shaped surface intended to effectively and efficiently remove dirt, mud, and other debris from vehicle tires. Here are 5 reasons why they are the better option:

  • Durability and Strength: 

High-density polyethylene (HDPE), the material used to make DiamondTrack reusable construction exit mats, offers exceptional strength and durability. Compared to other trackout mats, the diamond-shaped features on each mat provide 30% more surface area for tire contact, with an ultimate crush strength of 45,000 lbs per diamond feature rating of 800 psi – depending on subsurface conditions. This design ensures that various truck tires can deform elastically, forcing sediment off and keeping public roads clean.

  • Cost-Effectiveness: 

DiamondTrack mats don't need to be replenished like rock pads. They are virtually maintenance-free from the initial installation and can be left in place for the duration of the project, which considerably lowers long-term expenses.

  • Reusability

One of the key features of composite mats for construction is their reusability. They can be cleaned and reused on multiple job sites for up to 10 years, providing a substantial return on investment. To give you an idea, in contrast, rock trackout pads must be discarded after each project, resulting in higher and repeated costs.

  • Ease of Installation and Removal

Without the need for large machinery, DiamondTrack mats can be quickly installed across various surfaces, including unexcavated soil, concrete, asphalt, and pavement. This flexibility streamlines both the installation and removal process, saving time and reducing labor costs at the end of the project.

  • Compliance with Environmental Regulations

DiamondTrack helps contractors meet SWPPP requirements for Stabilized Construction Exits (SCE) and other Best Management Practices (BMP). By preventing sediment from leaving the site, these mats eliminate the risk of non-compliance fines and reduce the environmental impact of construction activities.

Reusable Mats Versus Traditional Rock 

Let’s take into consideration the importance of not only the upfront costs but also the long-term savings. Rock trackout pads may seem cheaper initially due to the availability of materials, but the ongoing expenses can add up quickly. When you add up the additional expenses of:

  • Replenishment costs
  • Cleanup costs
  • Compliance penalties

They can quickly exceed the initial investment in choosing a long-lasting, high-quality composite mat solution. The clear winner is DiamondTrack reusable construction exit mats, designed to last up to 10 years and provide a quick return on investment after just a few uses.

 

Environmental Benefits

The fact that reusable construction exit mats are good for the environment is another major benefit. Composite mats reduce the amount of waste that reaches public roads and rivers by preventing trackouts more effectively than rock pads. Not only assisting contractors in meeting environmental criteria but also helping to shield ecosystems from damaging chemicals. Composite mats have multiple sustainable benefits

  • They last over 10 years, significantly reducing waste compared to traditional mats that may only last a few months to a few years.
  • At the end of their life, composite mats are recyclable and can be downcycled for other uses, minimizing environmental impact and supporting a circular economy.
  • Composite mats do not absorb chemicals or invasive species, helping prevent cross-contamination and avoiding regulatory issues related to wood mat restrictions.
  • Fewer trucks are required to transport composite mats compared to traditional materials, reducing fuel consumption and lowering the carbon footprint.

Key Takeaways:

  • Reusable construction mats last up to 10 years, reducing long-term costs and waste.
  • Rock trackout pads require frequent replenishment and maintenance, leading to higher long-term costs and inefficiencies.
  • DiamondTrack™ mats are more durable and effective at sediment removal than rock trackout systems.
  • Virtually maintenance-free, reusable composite mats minimize labor and transportation costs.
  • Compliance with SWPPP and environmental regulations is easier with reusable mats.
  • Composite mats offer substantial ROI, reducing replenishment and cleanup expenses. Plus, they are recyclable and sustainable.
