CORE GRASS brings together grid, mesh and mat routes for reinforcing or protecting grassed areas. The correct product depends on whether the area carries pedestrians, occasional cars, regular vehicles or heavier operational traffic.

CORE GRASS
Reinforce planted surfaces for parking, access and pedestrian use.
- Material
- Recycled HDPE
- Panel size
- 800 × 800 mm
- Wall thickness
- 3.5 mm
The selected grid or protection layer spreads use across the surface while leaving openings for soil, roots and drainage. Establishment, soil profile and maintenance remain part of the system.
Choose the CORE GRASS route when the finished surface needs to remain planted. Use a gravel-stabilisation product instead where a controlled aggregate finish is required.

Selection
Choose it for the right reasons.
- Parking that must remain visually green
- Occasional or regular access across grass
- Overflow areas integrated into landscape
- Reducing rutting and surface damage under defined use
Limitations
Check the interfaces.
The CORE GRASS products are not interchangeable; each has a different traffic and installation scope.
Healthy establishment depends on soil, seed or turf, drainage, irrigation and maintenance.
Traffic intensity, turning and seasonal ground conditions must be considered before selection.
Installation overview
Build it in the right sequence.
- 01
Prepare the project-designed formation and sub-base and install any specified geosynthetic.
- 02
Install edge restraint and a level bedding layer.
- 03
Clip and support grids, cutting cleanly around fixed interfaces.
- 04
Fill with the specified growing medium, water and seed or turf.
- 05
Protect the area from traffic until sufficiently established, then maintain soil level and grass health.
Use the current exact product document, approved project detail and site inspection plan.

Straight answers
CORE GRASS questions.
Which CORE GRASS product should I use?
Start with the intended traffic, frequency, ground condition and whether the area is newly constructed or existing grass. CORE can then identify the appropriate grid, mesh or mat route.
Is CORE GRASS suitable for permanent parking?
Selected grid products can be used for permanent or overflow parking, but the full construction, traffic intensity, establishment and maintenance plan must suit the proposed use.
Does the grid alone keep the grass healthy?
No. The grid provides reinforcement, but the growing medium, drainage, grass specification, irrigation, establishment period and maintenance determine the planted finish.
