Common questions
Why does wet sand weigh more?
Water fills the voids between grains, adding mass without much volume — wet sand can be 20% heavier per m³ than dry sand.
How much sand for a paver base?
A typical 2.5–5 cm sand bedding layer under pavers uses roughly 40–80 kg per m². Use this calculator with your exact depth.
