The grass lattice is made of modified high molecular weight HDPE, which is environmental and 100% recyclable; it is perfect in combination of turf and car parking, which is pressure resistant, wear resistant, impact resistant, ageing resistant and corrosion resistant. It improves level of landscape and saves the cost of construction. It’s unique flat lap joint saves labor and time, and the expansion joints can be adjusted.
In Many residential quarters, there are green belt on both sides of the road, and the lawn generally stretches to the roadside. The soil of this green belt is seriously knotted due to negligence in the management. Grass planting grid has exactly solved this problem. It is also widely used in fire escapes and car parks. It solves the problem of increasing Greenland and improves ecological environment and safety. As follows, there is an analysis about the construction and maintenance experience of the grass grid
Main options for Grass-Grids structure as follows:
1. plain soil ramming + melon slice + gravel + melon slice + grass planting grid + mixed nutrient soil
2. compacted plain soil + gravel + concrete base + melon slice + grass planting grid + mixed nutrient soil
3. compacted soil + crushed stone + concrete foundation + melon slice + non-woven blanket + grass lattice + mixed nutrient soil
From the analysis of the construction cases, we came to the following conclusions: for the first option, the advantage is smooth drainage, but after a long time, due to the ground is weight bearing, it is easy to collapse;
For the second option, it is easy to cause the loss of nutrient soil after a long time of collecting rainwater and the decline of nutrient soil in the grass planting grid;
For the third option, adding a non-woven blanket compartment, which can prevent the loss of nutrient soil and can also play a role in water retention
Therefore, after technicians discuss and combine the experience of doing vertical greening, we advise the third option.
