  • There are 1000 litres in one cubic metre
  • 1 cubic metre of product covers 10 square metres to a depth of 100mm
  • 20 x 50 litre bags of product make 1 cubic metre
  • A roll of turf covers 1 square metre. (0.5m wide x 2m long)
  • 1m3 Mulches / Soils / Lawn Builder - Covers 25m2 @ 40mm OR 50m2 @ 20mm
  • 1T Sand / Aggregate / Pebbles – Covers Approx. 14m2 @ 50mm
  • Concrete Mix - .5m3 = Approx. 1t
