Heavy-duty Ground Grids: Q & A

Are Heavy-duty Ground Grids winter-resistant?

Heavy-duty Ground Grids are frost-resistant. If installed correctly, they also prevent pavement deformations caused by temperature-caused length variations that may reach up to +/- 1.5%.

Are Heavy-duty Ground Grids plow-tolerant?

Heavy-duty Ground Grids are plow-tolerant. The plastic grids are strong. For example, a public parking lot in Montreal in the picture below. It was snow plowed for seven years by now, and Heavy-Duty Ground Grids are not damaged.

If you grow plants in the holes rather than fill them with gravel, the plants may be damaged by snow plowing.

The good news is you don't need too much snow removal in the areas paved with Heavy-duty Ground Grids. They are designed to avoid excessive water flow during snow melting. The water will be absorbed into the soil and used by the plants.

What plants can I use to fill Heavy-duty Ground Grids' holes?

Low-growing perennial grasses work pretty well with Heavy-duty Ground grids, especially self-repairing varieties. You can use other perennials (like creeping thyme) that are either not too fragile or repair themselves quickly after the damage.

Before using the plants with HDGGs, always consider how heavy the traffic is in the paved area. For example, if it is used for emergency access or episodical guest parking only, there are many perennials you can use, especially in sunny places, for example, white clover, self-repairing perennial ryegrass, timothy, sturdy fescues or a mix of these plants.

If the traffic is too heavy, better consider filling the grids with gravel, at least in the places with the highest traffic load.
