- Formation Integrity: A unique and strong grass grid snap-lap the whole pavement together into a flat overall, to avoid local depression, suitable for exercise, entertainment and leisure
- High Strength and Durability: Grass grid using patented technology, the maximum compression capacity is 200 tons per square meter, greater than regulatory requirements of the saving fire plane 32 tons per square meter. Its stable performance, anti-UV, anti acid corrosion, and anti-wear pressure make the fire exits, fire climb surface into a green surface.
- Permeability: Load-bearing layer of gravel to provide a good permeability function, the excess water into the ground and increase underground water storage to prevent subsidence. It's not only could oxygen permeability also can purify the air.
- Water Conservation: Grass has water conservation functions, which can reduce urban inland inundation.
- Good Weather Resistance: Grass grids can be used for snow riding channel for -40~90℃.
- Protection of Grass: Load-bearing layer of gravel to provide a certain amount of water features, enabling the growth of grass, grass can grow to the gravel layer.

- First, the soil layer need to be compacted and the density should be at least 85%.
- The thickness of the compacted gravel layer should be about 350mm. Spread the layer out and make it flat, laminate until it become densely.
- Pave 70mm thickness small gravel (20% soil, 20% sand mixed with 60% small gravel) as leveling layer.
- Pave Grass Grids, cut the grass grid into suitable shape by saw if need, please leave a little millimeter between the grids.
- After paving grass grids, if need, use the fixed nails to further strengthen the grass grids
- If plant with grass seed, load grass grids with planting soil, leave one centimeter, sow grass seeds and then sprinkle a thin layer of soil.
- If paving with turf, first full-filled the grass grid with planting soil, use scraping straightedge to make the surface flat, when paving the turf, leaving about 2cm gap to stagger the pavement. Watering until floating slurry, and then suppress turf into grass grid repeatedly with a small roller or plate vibration machine.
- Parking spaces can use the marble strips or other sectors to mark parking space, eye-catching hat tag is also can be use to embedded in the celluar grid as separator for parking.
- The lawn needs to mow 4 to 6 times a year. Please pay attention to timely removal of weed and fertilization. In the hot dry season, the lawn should be watering regularly or install automatic watering equipment to make the necessary conservation and management.
