Gravel Grid Gradient Calculator

Nidagravel® gravel stabilisation grids effectively prevent gravel from sliding down a slope over time. The large honeycomb panels or sheets are manufactured from plastic (a percentage of which is recycled) and backed with a membrane. Nidagravel® grids are simply laid over the prepared sub-base and cut to fit the required area, then filled with gravel. The honeycomb structure of the gravel stabilisation grids holds the gravel in place permanently within the hexagonal cells. This prevents gravel migrating down the slope, prevents loss of gravel and prevents ruts and potholes from developing. In addition to solving the problem of using gravel on a slope - Nidagravel® honeycomb grids provide a much more stable gravel surface that is firm underfoot, making the gravel slope easier to walk across. Nidagravel® creates a gravel surface that is wheelchair friendly, easy to walk on and push a pram or bike over as well drive and park on.
