Chambers of the deployed grids need to filled in with garden soil to a certain height in such a way that after a while (due to the process of spontaneous consolidation, assisted by uniform sprinkling) its surface would be 5 mm below the upper surface of the grid.
Grass should be planted in quantities meeting the official instructions of the plant producer. Provided that light soil is used, seeds can be mixed with soil and then used to fill in the chambers.
During the period of intensive grass growth, soil should be maintained moist and avoid prolonged parking of vehicles. When the grids are completely filled in with grass, the resulting surface can be treated as a regular lawn. All nurturing works i.e. fertilization, watering and mowing, should be done the same way as in the case of extensively exploited lawns.
