Now, some places are better to source sand than others.

Our preferred sources of sand include:

  • Quarries – where they actually manufacture sand.
  • Retail outlets – that access their sand from quarries.
  • Cement or Cinder block makers

You may even be able to obtain sand through commercial greenhouse operators in your area.

Regardless of the source, we recommend that you test the sand for suitability for use in iAVs……before you buy and transport it.

The places that we don’t recommend include beaches – because the sand almost always contains calcium carbonate.

The other places that we don’t like are river banks – where the sand is frequently full of pollutants – including pharmaceuticals, chemicals, heavy metals, sewage, and even nuclear waste.
