How much topsoil do I need for a garden bed or new lawn?+
For a new lawn, allow 100-150mm of topsoil or 80/20 turf underlay (so 0.1-0.15m³ per square metre — about 10-15 cubic metres for a 100m² lawn). For a new garden bed, 200-300mm depth is typical. The supplier will confirm quantity for your dimensions when you enquire.
What's VENM and ENM fill?+
VENM (Virgin Excavated Natural Material) is certified clean fill that has never been used or contaminated — straight from excavation. ENM (Excavated Natural Material) is similar but allows slight inclusions. Both come with documentation required for council-spec projects and contaminated-site work. Use the certified grade when council inspectors will check.
What's the difference between topsoil, vegie garden mix and potting mix?+
Topsoil is screened natural soil — used as a base layer under turf or for general gardening. Vegie garden mix is a premium organic blend designed specifically for raised beds and vegetable patches (higher organic matter, better nutrition). Potting mix (AS 3743) is engineered for containers — drains freely, doesn't compact, contains controlled fertiliser.
