Sketch your area and note all perimeter measurements. Determine how many square metres your area is- this will tell you how many cubic metres of cracker dust you may need, roughly how much sand will need to be removed, and how much infill sand to apply after the artificial grass is installed.
Determine what lengths of artificial grass you will need to cover your area, squaring off sections that are not at a right angle. Keep pieces running in the same direction and find out the available roll widths for your choice of artificial grass. Factor in additional width and length to allow for cutting in your artificial grass to fit your area.
