GrassRoll Extra Grass Reinforcement Mat 2x5m up to 7.5t

Professional solution for demanding parking

The GrassRoll Extra 7.5t mat with dimensions of 2x5m is the most powerful option among our grass reinforcement variants. Its profile measures 14.5 mm and its surface weight reaches 2 kg/m², making it ideal for areas with regular traffic. It works excellently for permanent parking lots, access roads, and frequently used grassy areas where ordinary meshes would fail.

This system preserves the natural green color of the landscape while offering sufficient strength for both cars and trucks, without the need for extensive excavation work or concreting.

Why choose GrassRoll Extra?

GrassRoll Extra is not just an ordinary mesh, but an engineered system combining maximum durability with easy installation. Here are the reasons why it is the best choice for your parking area:

• Extreme load capacity up to 7.5 tons: Handles not only cars, but also heavier SUVs and vans (axle load).
• No excavation or digging: Save on earthworks – installs directly onto the existing lawn.
• Safe walking: The unique oscillating structure (3D profile) ensures better traction and prevents slipping, even when the grass is wet.
• Preserves greenery: Unlike concrete blocks, it doesn't overheat in summer or dry out the grass, keeping the area naturally green.
• Easy installation: Unroll the mat, let it "settle," and then apply it – fast and simple without effort.
• Eco-friendly and sustainable: Made from recycled polymers and fully permeable to water (SuDS compatible).
• Certification: One of the few mats certified for parking on grass without soil replacement.

Unique structure and durability

The Grassroll mat is made from chemically inert, recycled high-density polyethylene (HDPE). Its specific oscillating design is not just a visual element – it was created to improve traction and slip resistance.

The grid protects grass roots from direct contact with wheels, preventing soil compaction and rutting. The material is UV-stabilized, ensuring a long service life even when exposed to direct sunlight.

• High tensile strength (14 kN/m).
• Resistance to rot and biological influences.
• Environmentally friendly (100% recyclable).

Where can you use GrassRoll Extra?

Thanks to its extreme load capacity (up to 7.5 tons per axle on a firm base), GrassRoll Extra is designed for the most demanding applications among grass reinforcement mats. It is a great solution for places that need to withstand more than just occasional traffic.

In addition to parking lots, the mat is also suitable for reinforcing surfaces for events and festivals, or as an access road for maintenance vehicles in parks and gardens.

• Permanent and temporary parking lots.
• Driveways to houses and garages.
• Areas for caravans and campsites.
• Barrier-free access for wheelchairs.

Step 1: Terrain preparation is key

The key to long service life and functionality of the system is a quality base. The surface must be level, firm, and able to drain water. Before installation, we recommend mowing the existing lawn as short as possible, or locally reseeding grass seed.

Any bumps, holes, or depressions must be leveled by filling with sandy soil (a mixture of sand and clay) and compacted. If the base is waterlogged or unstable, it must first be reinforced (e.g., with a gravel bed), otherwise the mat will not function properly.

Step 2: Unrolling the Grassroll

Since GrassRoll is supplied in rolls, it tends to curl after unpacking. Before anchoring, it is necessary to unroll the mat to its final location and let it "rest" for at least 1 hour so that it regains its natural flatness.

The ambient temperature significantly affects the time needed for flattening – in cold weather, it may take longer. We recommend loosely securing the corners with pegs so that the mat does not shift while "acclimatizing." Only once the mat has flattened out should you proceed with final anchoring using staples.

Step 3: Anchoring technique for maximum stability

Secure anchoring is the most important part of the installation. For one roll (2m x 5m), it is recommended to use at least 30 steel U-pins, which are included in the package. From experience, it is advisable to use twice the number of steel staples.

Recommended anchoring pattern:

• Outer edges: Anchor every 300–350 mm.
• Center of the area: Create a "chevron" pattern in 3 rows, with a spacing of 500 mm across and a maximum of 750 mm along the length.
• Drive the staples parallel to the mesh cells so they do not stick out and damage the mower blades when mowing.

Step 4: Joining rolls and important details

When installing multiple rolls next to each other, never overlap them. Lay the mats tightly against each other. Secure the joint with a single row of staples that catches the edges of both adjacent mats at once.

Watch out for temperature: Plastic reacts to temperature changes. If you install the mat in cold weather, leave a gap of approximately 10-15 mm between individual rolls. This expansion gap allows the material to expand during hot summer days without the surface buckling.

Care and use after installation

After anchoring, you can lightly dust the surface with sandy soil to level out minor depressions, but the mat must not be completely covered. For the best results, we recommend not driving on the area during the growing season, approximately 6-8 weeks, until the grass has grown through the grid.

If immediate use is necessary, it is possible, but expect reduced traction when wet and slower grass growth. Mowing is carried out as standard, but for the first 3 to 4 mowings, set the mower blades to a higher level.
