If you are not sure how much soil you need for the job, measure the length x width x depth = total Cubic Metres required
eg: 10m x 6m x 0.05m (50mm) = 3m3
1m3 @ 100mm Thick ≈ 10m2
1m3 @ 75mm Thick ≈ 13m2
1m3 @ 50mm Thick ≈ 20m2
6×4 Trailer Load = 2 Scoops ≈ 0.7 Cubic Metres
3 Scoops = 1.5 Trailer Loads ≈ 1 Cubic Metre
eg: 3 Trailer Loads ≈ 2 Cubic Metres
