How To Protect and Strengthen Grass with Grass Reinforcement Mats

How To Protect and Strengthen Grass with Grass Reinforcement Mats

Grass reinforcement mats, also known as grass protection mats or turf reinforcement mats, are products designed to help strengthen and protect natural grass surfaces. They are commonly used in various applications where maintaining healthy grass cover is important while also accommodating occasional or even frequent vehicular or pedestrian traffic.

Construction and Composition

Grass reinforcement mats are typically made from materials such as high-density polyethylene (HDPE), rubber, or other durable synthetic materials. They are usually designed with an open, grid-like structure or a pattern of perforations to allow grass to grow through them.


  • Vehicle Access: Grass reinforcement mats are often used to create
    temporary or semi-permanent pathways, parking areas, or access roads over grassy areas, allowing vehicles to pass without causing significant damage to the underlying turf.
  • Erosion Control: They can be used on slopes and embankments to prevent soil erosion, especially in areas prone to heavy rainfall or runoff.
  • Event Grounds: Grass reinforcement mats are also used in event venues like sports fields or festival sites to protect the grass from damage during events.


  • Protects Grass: The mats distribute the weight of vehicles or foot traffic, reducing the compaction of soil and minimising damage to the grass.
  • Promotes Drainage: They often improve surface drainage, allowing rainwater to infiltrate the soil more effectively, which can help maintain a healthy grass cover.
  • Easy Installation: Grass reinforcement mats are relatively easy to install, and they can be rolled out over the grass surface or installed in grids.
  • Grass Growth: The open design of these mats enables grass to grow through them, so over time, they become less visible as the grass cover develops.


  • There are various types of grass reinforcement mats, including roll-out mats, interlocking panels, and cellular confinement systems. The choice of mat type depends on the specific application and load-bearing requirements.

Environmental Considerations

  • Grass reinforcement mats are generally designed to be environmentally friendly, as they support grass growth and help with erosion control.


  • Periodic maintenance may be required to ensure that the grass continues to grow through and around the mats, and to remove any debris or organic material that might accumulate on the surface.
  • Grass reinforcement mats provide a practical solution for preserving natural grass surfaces in areas where they might be subjected to heavy use or potential damage. They are commonly used in landscaping, construction sites, parks, sports fields, and other similar settings.

How to use, lay and cut grass reinforcement mats

Using, laying, and cutting grass reinforcement mats involves a series of steps to ensure proper installation. 

Always follow the manufacturer's guidelines and recommendations for the specific type of grass reinforcement mats you are using, as they may have specific requirements and best practices for installation and maintenance.

Using Grass Reinforcement Mats

Site Preparation: Before installing grass reinforcement mats, assess the site and prepare the ground. Ensure that the soil is level, free from weeds, and well-drained. Remove any debris or rocks from the area.

Layout Plan: Plan the layout of the mats according to your specific requirements. Consider the intended use, traffic patterns, and any curves or turns in the pathway or area you're protecting.


    • Roll Out Mats: If you have roll-out mats, simply unroll them over the prepared surface. Ensure that the mats are properly aligned and snugly fitted together.
    • Interlocking Panels: If using interlocking panels, assemble them according to the manufacturer's instructions. They should form a stable, interconnected surface.
    • Grass Mats can be installed with plastic or biodegradable reinforcement pegs. See here for a suitable range of pegs.

Grass Growth: Over time, grass will grow through the openings in the mats. Maintain regular watering and provide proper care to promote grass growth. Consider using grass seed or sod to accelerate the process.

Cutting Grass Reinforcement Mats

Measuring Determine the specific dimensions or shape you need for your grass reinforcement mats. Measure the area and mark the mats accordingly with chalk or a marker.

Safety Gear: Wear appropriate safety gear, such as gloves and safety goggles, to protect yourself while cutting the mats.

Cutting Tools: You can cut grass reinforcement mats with various tools, including a utility knife, a circular saw with a fine-toothed blade, or even heavy-duty scissors. The choice of tool depends on the thickness and material of the mats.

Cutting Technique:

    • For straight cuts, use a straightedge or ruler as a guide to ensure a clean, straight cut.
    • For curves or rounded cuts, use a utility knife or scissors for more precise results. Take your time and follow the marked lines carefully.

Quality Control: After cutting, ensure that the edges are smooth and free from jagged or rough edges. This will help prevent tripping hazards and ensure a neat appearance.


      • If you've cut the mats to fit a specific area, lay them according to your initial installation instructions, making sure they align properly with adjacent mats.
      • Proper installation and cutting of grass reinforcement mats are essential to ensure they function effectively and provide a stable, grass-covered surface.

Mowing and Maintenance

Mowing grass with grass reinforcement mats in place is a straightforward process, but it requires some considerations to ensure that the mats are not damaged, and the grass is mowed effectively. Additionally, cleaning the mats periodically can help maintain their appearance and functionality.

Mowing Grass with Grass Reinforcement Mats

Choose the Right Equipment: Use a lawn mower suitable for the specific type of grass you have and the height at which you want to maintain it. Depending on the height of the grass and the type of mats, a standard push mower, a ride-on mower, or a trimmer may be appropriate.

Check the Grass Height: Ensure that the grass height is appropriate for mowing. The grass should be neither too short nor too long. Most grasses should be maintained at a height of about 2.5 to 4 inches (6.35 to 10.16 cm).

Mowing Technique: When mowing over grass reinforcement mats, follow these guidelines:

  • Avoid sudden turns or abrupt movements that can cause damage to the mats.
  • Mow in a straight, back-and-forth pattern rather than in circles or sharp angles.
  • Take your time and mow at a steady pace to ensure an even cut.
  • Adjust Mower Height: Some grass reinforcement mats may sit slightly above the surrounding grass level. Adjust your mower's cutting height to accommodate this and ensure a consistent cut across the entire area.

Maintenance: After mowing, inspect the mats for any damage or signs of wear. Repair or replace damaged mats as needed to maintain their integrity.

Cleaning Grass Reinforcement Mats:

Cleaning grass reinforcement mats is essential to maintain their appearance and prevent the build-up of debris that can impede grass growth.

Regular Debris Removal: Periodically remove leaves, grass clippings, and other debris that accumulate on the surface of the mats. Use a broom, leaf blower, or rake to clear the mats.

Pressure Washing: For more thorough cleaning, you can use a pressure washer to remove dirt, mud, and other stubborn stains from the mats. Use a wide-angle nozzle and low pressure to avoid damaging the mats. Ensure that the pressure washer is at a safe distance from the mats.

Gentle Cleaning Solutions: For stubborn stains or discoloration, you can use a mild detergent or a mixture of water and vinegar. Apply the solution to the mats, scrub gently with a soft brush, and then rinse thoroughly.

Avoid Harsh Chemicals: Avoid using harsh chemicals or abrasive cleaners, as they can damage the mats and negatively affect grass growth.

Inspect for Damage: While cleaning, inspect the mats for any signs of damage, such as cracks or warping. Address any issues promptly to ensure the continued functionality of the mats.

By following these guidelines for mowing and cleaning grass reinforcement mats, you can help maintain a healthy grass cover while keeping the mats in good condition for an extended period. Regular maintenance and care are key to ensuring the longevity and effectiveness of these mats.
