CORE GRASS 40 is an 800 × 800 mm recycled-HDPE grid that is filled with a compatible growing medium to reinforce planted parking or access surfaces. Grass performance still depends on soil, drainage, establishment, irrigation and maintenance.

Where it can be considered.
- Domestic grass parking
- Shared parking
- Light commercial access
- Overflow parking
Limitations
Where judgment is required.
The grid reinforces a planted system; it cannot compensate for unsuitable soil, drainage or maintenance.
Turning, braking, frequency and seasonal ground conditions must be assessed.
Protect the installed surface until the grass is adequately established.
Do not treat a published traffic description as a project-specific load certification.
Installation overview
Sequence the interfaces.
- 01
Prepare the formation and project-designed sub-base; install any specified geosynthetic layer.
- 02
Install continuous edge restraint and a uniform bedding layer.
- 03
Clip grids together, cut around interfaces and keep panels fully supported.
- 04
Fill with the specified growing medium, water and seed or turf as directed.
- 05
Protect from traffic during establishment; current published guidance indicates approximately 4–6 weeks, subject to growing conditions.

Straight answers
CORE GRASS 40 questions.
What is the difference between CORE GRASS 40 and the other depth?
CORE GRASS 40 is positioned for domestic, shared and lighter commercial traffic; CORE GRASS 50 is the deeper route for more demanding commercial uses.
How long before traffic?
The current published guidance indicates approximately 4–6 weeks for establishment, but actual readiness depends on season, grass growth, soil, irrigation and site conditions.
Does the grid guarantee healthy grass?
No. Growing medium, drainage, species, establishment and maintenance determine the planted finish.
